How Sonar Works
Sonar technology is based on sound waves. The Fishing System uses sonar to
locate and define structure, bottom contour and composition, as well as depth
directly below the transducer.
Your Fishing System sends a sound wave signal and determines distance by
measuring the time between the transmission of the sound wave and when the
sound wave is reflected off of an object; it then uses the reflected signal to
interpret location, size, and composition of an object.
Sonar is very fast. A sound wave can travel from the surface to a depth of 240
ft (70 m) and back again in less than 1/4 of a second. It is unlikely that
your boat can “outrun” this sonar signal.
1
SONAR is an acronym for SOund and NAvigation Ranging. Sonar utilizes precision
sound pulses or “pings” which are emitted into the water in a teardrop-shaped
beam. The sound pulses “echo” back from objects in the water such as the
bottom, fish and other submerged objects. The returned echoes are displayed on
the LCD screen. Each time a new echo is received, the old echoes are moved
across the LCD, creating a scrolling effect.
When all the echoes are viewed side by side, an easy to interpret “graph” of
the bottom, fish and structure appears.
Introduction
Introduction
The sound pulses are transmitted at various frequencies depending on the
application. Very high frequencies (455 kHz) are used for greatest definition,
but the operating depth is limited. High frequencies (200 kHz) are commonly
used on consumer sonar and provide a good balance between depth performance
and resolution. Low frequencies (83 kHz) are typically used to achieve greater
depth capability.
The power output is the amount of energy generated by the sonar transmitter.
It is commonly measured using two methods:
· Root Mean Square (RMS) measures power output over the entire transmit cycle.
· Peak to Peak measures power output at the highest points.
The benefits of increased power output are the ability to detect smaller
targets at greater distances, ability to overcome noise, better high speed
performance and enhanced depth capability.

High Definition Side Imaging® Sonar
(898c SI and 998c SI only)
The 898c SI Combo and 998c SI Combo use Side Imaging® sonar to provide a wide
yet precise survey of a large area of water, including detailed bottom
topography and fish-attracting structure orientation. The Side Imaging®
transducer returns are processed into an image similar to an aerial
photograph.
Typically, the Side Imaging® sonar can search an area that is 480 feet wide
(240 to each side), with a typical depth performance of 150 feet when the Side
Imaging® Sonar frequency is set for 455kHz. The side beams can be operated at
one of two frequencies: 455 kHz or 800 kHz. Selecting 800 kHz produces the
sharpest image, but the search area to each side and the depth capability are
limited as compared to the 455 kHz frequency. See What’s on the Side Imaging®
Display and Understanding Side Imaging® for more information.
DualBeam PLUSTM Sonar
(858c, 898c SI, 958c, 998c SI)
The Fishing System uses a 200/83 kHz DualBeam PLUSTM sonar system with a wide
(60°) area of coverage. DualBeam PLUSTM sonar has a narrowly focused 20°
center beam, surrounded by a second beam of 60°, expanding your coverage to an
area equal to your depth. In 20 feet of water, the wider beam covers an area
20 feet wide.
DualBeam PLUSTM sonar returns can be blended together, viewed separately, or
compared side-by-side. DualBeam PLUSTM is ideal for a wide range of conditions
– from shallow to very deep water in both fresh and salt water. Depth
capability is affected by such factors as boat speed, wave action, bottom
hardness, water conditions, and transducer installation.

QuadraBeam PLUSTM Sonar
(optional-purchase QuadraBeam PLUSTM
transducer only)
Your Fishing System supports the optional-purchase QuadraBeam PLUSTM
transducer. QuadraBeam PLUSTM sonar provides a wide (90°) area of coverage.
QuadraBeam PLUSTM starts with two fan-shaped 35° 455 kHz Side Structure
locating sonar beams to spot fish, bait, and structure to the left and right
of the boat over an area of the bottom that’s always equal to twice your
depth.
For a detailed view below the boat, QuadraBeam PLUSTM uses DualBeam PLUSTM technology, with precision 20° and wide 60° beams. QuadraBeam PLUSTM finds more fish faster, and can even tell you where to put your bait by showing if fish are to the left, right, or directly beneath your boat.

Introduction
Universal Sonar 2
Your Fishing System supports Universal Sonar 2, a state-of-the-art, integrated
and protected transducer that is built into the lower unit of Minnkota
trolling motors. With Universal Sonar 2, all wiring is concealed inside the
indestructible composite shaft–out of sight and out of harm’s way, with no
clamps, ties, or exposed wires. Universal Sonar 2 features new temperature
sensing and the performance of DualBeam PLUSTM technology. An expanded view
and greater bottom detail gives you a totally new perspective of the water

Your Fishing System also supports GPS (Global Positioning System) and
chartplotting. It uses GPS and sonar to determine your position, display it on
a grid, and provide detailed underwater information.
GPS uses a constellation of satellites that continually send radio signals to
the earth. The GPS receiver on your boat receives signals from satellites that
are visible to it. Based on time differences between each received signal, the
GPS receiver determines its distance to each satellite. With distances known,
the GPS receiver mathematically triangulates its own position. With once per
second updates, the GPS receiver then calculates its velocity and bearing.
GPS was originally intended for military use; however, civilians may also take
advantage of its highly accurate position capabilities, typically within +/-
4.5 meters, depending on conditions. This means that 95% of the time, the GPS
receiver will read a location within 4.5 meters of your actual position. Your
GPS Receiver also uses information from WAAS (the Wide Area Augmentation
System), EGNOS (the European Geostationary Navigation Overlay Service), and
MSAS (the MTSAT Satellite Augmentation System) satellites if they are
available in your area.
The following GPS functionality is currently supported by the Fishing System
when it is connected to the included GPS receiver:
· View current position
· View current track (breadcrumb trail)
· View precision speed and heading from your GPS receiver
· Save tracks, waypoints, and routes
· Travel a route and navigate from one waypoint to the next.

Installation Overview
Inside the boat there is often a channel or conduit used for other wiring,
this can be used to route cables. Be sure to route the cable as far as
practical from the antenna cable of VHF radios or tachometer cables to reduce
the possibility of interference. The transducer and GPS receiver cables should
not be cut, and care should be used not to damage the cable insulation. Basic
installation tasks that you must perform include:
· Installing the control head (choose gimbal or in-dash mounting, where in-
dash mounting requires a separate purchase)
· Installing the transducer (choose the installation method that matches your
transducer)
· Installing the GPS Receiver (if included) · Testing the complete
installation and locking the transducer position
NOTE: Accessories may require a separate purchase. You can visit our web site
at humminbird.com to order these accessories online or contact our Customer
Resource Center at 1-800-633-1468.

Control Head Installation
You have two choices for mounting your control head, Gimbal mounting, where
you use a surface on the boat, such as the dash, to mount the control head so
that it can be tilted up or down, or In-dash mounting, which requires a
separate purchase.
Installation Introduction

Gimbal Mounting the Control Head
If you are gimbal mounting the Humminbird®, you can pre-assemble the unit in
order to plan the best mounting location.
1 2
3
1 Washer 2 Gimbal Knob 3 Gimbal Bracket
In addition to the hardware supplied with your control head, you will need a
powered hand drill and various drill bits, various hand tools, including a
Phillips head screwdriver, a socket wrench and a flat head screwdriver, a
marker or pencil, safety glasses and dust mask, and marine-grade silicone
sealant.
1. Place the control head into the gimbal bracket. Make sure that the
straight side of the gimbal arm is against the back side of the control head.
2. Place a 1″ (25 mm) diameter black washer on the gimbal knob and then
thread the knob and washer into the housing. Tighten the gimbal knob to secure
the control head to the mount. Repeat step 2 for the other side.
You can now place the control head in various locations to decide which is
best for mounting. Rotating the mounting bracket to the top of the control
head will allow for overhead mounting. The chosen mounting area should allow
for sufficient room so the control head can pivot through the full tilt range
and allow for easy removal and installation.
NOTE: You can drill the cable pass hole underneath the gimbal bracket,
allowing you to thread the cables through the knock-out holes in the mount;
however, if you cannot drill the hole directly under the mounting bracket,
then you will need to drill the cable pass hole behind the bracket, and will
need to mount the hole cover there instead.
NOTE: When drilling holes in fiberglass hulls, it is best to start with a
smaller bit and use progressively larger drill bits to reduce the chance of
chipping or flaking the outer coating. Fill all holes with marine grade
silicone sealant.
NOTE: You must have underside access to the mounting location to pass the
cables through to the surface. Also, make sure that the mounting surface is
adequately supported to protect the control head from excessive wave shock and
vibration and provide visibility while in operation.
3. After the mounting location has been determined, loosen the gimbal knobs
and remove the control head from the gimbal bracket.
7
Installation – Gimbal Mount
NOTE: Alternate hole patterns are available on the gimbal mounting bracket, and may match existing holes on the boat. You may choose to use one of these alternate hole patterns.
4. Place the gimbal bracket in the chosen position on the mounting surface and mark the four mounting screw locations using a pencil or center punch.
NOTE: Go to the installation instructions applicable to your transducer, GPS
Receiver and accessories. Make the required installations and then run the
cables to your control head mounting location. Do not cut any cabling (except the
1
power cable). If your cables are too short, extensions are available from your local
dealer or online from humminbird.com.

5. Set the gimbal bracket aside and drill the four mounting screw holes using a 5/32″ (4.0 mm) drill bit.
6a. If the cables must pass through a hole directly beneath the mounting bracket, mark and drill an additional 1″ (25 mm) hole centered between the four mounting holes. Route the cables through the 1″ hole. Place the hole cover over the mounting surface hole, then use it to mark the position of the two mounting screws.
8
Remove the hole cover, drill the two mounting holes using a 9/64″ bit. Do not
install the hole cover at this time.
6b. If the cables cannot be routed directly beneath the mounting bracket, mark
and drill a 1″ (25 mm) hole that will allow you to run the cables close to the
bracket. Pass the cables through the 1″ (25 mm) hole, routing the cables
through the grommet and pressing the grommet into place. Place the hole cover
over the mounting surface hole, then use it to mark the position of the two
mounting screws. Remove the hole cover, drill the two mounting holes using a
9/64″ (3.5 mm) bit, fill them with marine-grade silicone, then replace the
hole cover and insert the #8 Phillips countersink wood screws. Hand-tighten
only.
7. Place the mounting bracket on the mounting surface aligned with the
drilled holes and fill the mounting holes with marine grade silicone. Insert
the four #10 Slotted-Hex wood screws into the mounting holes. Hand-tighten
only.
8. If the cable pass through-hole is beneath the mounting bracket, you will
need to install the hole cover. Place the hole cover over the mounting bracket
cable pass through-hole and align with holes drilled in step 6a. Insert the #8
Phillips countersink wood screws. Hand tighten only.
NOTE: Be sure that the cables pass through the slots on the hole cover and
that there is enough cable slack to allow for the control head to pivot
through its full tilt range. Extra cable slack will also help when
connecting/disconnecting the cables.

NOTE: The tab on the Cable Collector insert goes into the slot on the cover.
Connecting the Control Head Power Cable to the Boat
A 6′ (2 m) long power cable is included to supply power to the control head.
You may shorten or lengthen the cable using 18 gauge multi-stranded copper
wire.
CAUTION: Some boats have 24 or 36 Volt electric systems, but the control head
MUST be connected to a 12 VDC power supply.
The control head power cable can be connected to the electrical system of the
boat at one of two places: a fuse panel usually located near the console, or
directly to the battery.
11. Attach the cable collector insert to the cable collector cover using the 2 Phillips screws provided.
PO ISITIIVVEE
12. Place the control head back onto the mounting bracket. Plug in the cable
collector assembly to the back of the control head. Cable connectors and cable
sockets are keyed to prevent reverse installation, so be careful not to force
the connectors into the wrong sockets. Once the cable collector and all cables
are plugged into the back of the control head, lock the assembly into place by
threading the knurled screw into the threaded insert on the back of the
housing. Adjust the control head to the desired viewing angle and secure by
tightening the gimbal knobs.
NOTE: You may wish to dress the cabling with nylon wire ties in order to hold
the cables together and create a cleaner assembly.

NOTE: Make sure that the power cable is disconnected from the control head at
the beginning of this procedure. NOTE: Humminbird® is not responsible for
over-voltage or over-current failures. The control head must have adequate
protection through the proper selection and installation of a 3 amp fuse.
The Humminbird® control head is now ready for operation.

Installation – Power
1a. If a fuse terminal is available, use crimp-on type electrical connectors
(not included) that match the terminal on the fuse panel. Attach the black
wire to ground (-), and the red wire to positive (+) 12 VDC power. Install a 3
amp fuse (not included) for protection of the unit. Humminbird® is not
responsible for overvoltage of over-current failures.

858c & 958c Transom Mount Transducer Installation
DualBeam PLUSTM Transducer, XNT 9 20 T (858c and 958c only)
The DualBeam PLUSTM transducer uses a Two Piece Kick-up transducer mounting
bracket.
NOTE: Due to the wide variety of hulls, only general instructions are
presented in this installation guide. Each boat hull represents a unique set
of requirements that should be evaluated prior to installation. It is
important to read the instructions completely and understand the mounting
guidelines before beginning installation.
NOTE: Your transducer may not look exactly like the transducer shown in the
illustrations, but it will mount in exactly the same way.
Overview
If you will be installing a DualBeam PLUSTM transom mounted transducer, use
the procedures in this section. There are several procedures you will have to
perform in order to install a transom-mounted transducer. They are as follows:
· Locate the transducer mounting location · Prepare the mounting location ·
Assemble the transducer and perform initial mounting · Route the transducer
cable · Connect the transducer cable · Perform a final test of the transom
transducer installation. In addition to the hardware supplied with your
transducer, you will need a powered hand drill and various drill bits, various
hand tools, including a ruler or straightedge, a level, a 12″ plumb line
(weighted string or monofilament line), marker or pencil, safety glasses and
dust mask, and marine-grade silicone sealant.
NOTE: When drilling holes in fiberglass hulls, it is best to start with a
smaller bit and use progressively larger drill bits to reduce the chance of
chipping or flaking the outer coating.
13
Transom Mount – DualBeam PLUSTM
1. Locating the transducer mounting location
NOTE: If transom mounting is not possible because of a stepped hull or
cavitation noise, and you have a single layer fiberglass hull, In-hull
installation is an option. See Inside the Hull Transducer Installation for
more information.
Turbulence: You must first determine the best location on the transom to install the transducer. It is very important to locate the transducer in an area that is relatively free of turbulent water. Consider the following to find the best location with the least amount of turbulence:
· As the boat moves through the water, turbulence is generated by the weight of the boat and the thrust of the propeller(s) – either clockwise or counter- clockwise. This turbulent water is normally confined to areas immediately aft of ribs, strakes or rows of rivets on the bottom of the boat, and in the immediate area of the propeller(s). Clockwise propellers create more turbulence on the port side. On outboard or inboard/outboard boats, it is best to locate the transducer at least 15″ to the side of the propeller(s).
Areas of Possible Turbulence
Stepped Hull
· The best way to locate turbulence-free water is to view the transom while
the boat is moving. This method is recommended if maximum high-speed operation
is a high priority. If this is not possible, select a location on the transom
where the hull forward of this location is smooth, flat and free of
protrusions or ribs.

Deadrise Angle
· On boats with stepped hulls, it may be possible to mount the
transducer on the step. Do not mount the transducer on the transom
behind a step to avoid popping the transducer out of the water at
higher speeds; the transducer must remain in the water for the
Rib
control head to maintain the sonar signal.
14
· If the transom is behind the propeller(s), it may be impossible to find an
area clear from turbulence, and a different mounting technique or transducer
type should be considered, such as an Inside the Hull Transducer (see Inside
the Hull Transducer Installation).
· If you plan to trailer your boat, do not mount the transducer too close to
trailer bunks or rollers to avoid moving or damaging the transducer during
loading and unloading of the boat.
· If high speed operation is critical, you may want to consider using an In-
Hull transducer instead of this Transom Mount transducer.
NOTE: The hydrodynamic shape of your transducer allows it to point straight
down without deadrise adjustment.
NOTE: If you cannot find a transom mount location that will work for your
highspeed application, find an In-Hull Transducer by contacting our Customer
Resource Center at either
1-800-633-1468 or by visiting our web
site at humminbird.com.

2. Preparing the Mounting Location
In this procedure, you will determine the mounting location and drill two
mounting holes, using the transducer mounting bracket as a guide.
1. Make sure that the boat is level on the trailer, both from port to
starboard and from bow to stern, by placing your level on the deck of the
boat, first in one direction, then in the other.
2. Hold the mounting bracket against the transom of the boat in the location
you have selected. Align the bracket horizontally, using the level; make sure
that the lower corner of the bracket does not
NOTE: If you have a flat-bottomed aluminum boat, some additional adjustment
may be needed to accommodate the rivets on the bottom of the boat (i.e. the
gap may need to be a little smaller than 1/8″). This will help you to avoid
excessive turbulence at high speeds.
NOTE: If your propeller moves clockwise (in forward, as you’re facing the
stern of the boat from behind), mount the transducer on the starboard side,
and align the bottom right corner of the mounting bracket with the bottom of
the boat. If your propeller moves counter-clockwise (in forward, as you’re
facing the stern of the boat from behind), mount the transducer on the port
side, and align the bottom left corner of the mounting bracket with the bottom
of the boat.

3. Assembling the Transducer and Initial Mounting
In this procedure, you will assemble the transducer using the hardware
provided, then mount it and make adjustments to its position without locking
it in place.
NOTE: You will initially assemble the transducer and the pivot arm by matching
the two ratchets to a numbered position on the transducer knuckle. Further
adjustments may be necessary.
Mark Initial Drill Holes
Third Hole
3. Continue to hold the bracket on the transom of the boat, and use a pencil or marker to mark where to drill the two mounting holes. Mark the drill holes near the top of each slot, making sure that your mark is centered in the slot.
NOTE: The third hole should not be drilled until the angle and height of the transducer is finalized, which you will not do until a later procedure.
4. Make sure that the drill bit is perpendicular to the actual surface of the
transom, NOT parallel to the ground, before you drill. Using a 5/32″ bit,
drill the two holes only to a depth of approximately 1″.
NOTE: On fiberglass hulls, it is best to use progressively larger drill bits
to reduce the chance of chipping or flaking the outer coating.
1a. If you already know your transom angle, refer to the chart below for the initial position to use to set the ratchets. If your transom is angled at 14 degrees (a common transom angle for many boats) use position 1 for the ratchets. In either case, go to step 2.

3. Put the pivot bolt through the assembly to hold it in position and loosely
install the nut, but do NOT tighten the nut at this time. Insert the pivot arm
assembly into the mounting bracket. Do NOT snap the assembly closed, as you
will need to access the mounting bracket in the next step.
NOTE: If the pivot assembly is snapped closed over the mounting bracket, use a
flat head screwdriver or similar tool to gently pry the assembly away from the
mounting bracket.
4. Align the mounting bracket transducer assembly with the drilled holes in the transom. With a 5/16″ socket driver, mount the assembly to the transom using the two #10 – 1″ long screws provided.

8. Continue to adjust until the bracket is also level from port to starboard
(horizontally level as you look at the transducer from behind the boat).
9. Mark the correct position on the transom by tracing the silhouette of the
transducer mounting bracket with a pencil or marker.
10. Tighten the pivot bolt, using the pivot screw and nut to lock the
assembly. Hand tighten only!
11. Snap open the assembly and hand-tighten the two mounting screws, then
snap the assembly closed.
NOTE: You will drill the third mounting hole and finalize the installation
after you route the cable and test and finish the installation in the
following procedures.

4. Routing the Cable
The transducer cable has a low profile connector, which must be routed to the
point where the control head is mounted. There are several ways to route the
transducer cable to the area where the control head is installed. The most
common procedure routes the cable through the transom into the boat.
NOTE: Your boat may have a pre-existing wiring channel or conduit that you can
use for the transducer cable.
1. Unplug the other end of the transducer cable from the control head. Make
sure that the cable is long enough to accommodate the planned route by running
the cable over the transom.
CAUTION! Do not cut or shorten the transducer cable, and try not to damage the
cable insulation. Route the cable as far as possible from any VHF radio
antenna cables or tachometer cables to reduce the possibility of interference.
If the cable is too short, extension cables are available to extend the
transducer cable up to a total of 50′. For assistance, contact the Customer
Resource Center at humminbird.com or call
1-800-633-1468 for more information.
NOTE: The transducer can pivot up to 90 degrees in the bracket. Allow enough
slack in the cable for this movement. It is best to route the cable to the
side of the transducer so the transducer will not damage the cable during
movement.
2a. If you are routing the cable over the transom of the boat, secure the
cable by attaching the cable clamp to the transom, drilling 9/64″ diameter
holes for #8 x 5/8″ wood screws, then skip directly to procedure 5, Connecting
the Cable.
or…
Routing the Cable
2b. If you will be routing the cable through a hole in the transom, drill a 5/8″ diameter hole above the waterline. Route the cable through this hole, then fill the hole with marine-grade silicone sealant and proceed to the next step immediately.
3. Place the escutcheon plate over the cable hole and use it as a guide to mark the two escutcheon plate mounting holes. Remove the plate, drill two 9/64″ diameter x 5/8″ deep holes, and then fill both holes with marine-grade silicone sealant. Place the escutcheon plate over the cable hole and attach with two #8 x 5/8″ wood screws.
4. Route and secure the cable by attaching the cable clamp to the transom; drill one 9/64″ diameter x 5/8″ deep hole, then fill the hole with marine- grade silicone sealant, then attach the cable clamp using a #8 x 5/8″ screw.
5. Plug the other end of the transducer cable back into the control head connection holder.
Transom Mount – DualBeam PLUSTM
20
Storing Excess Cable
NOTE: If there is excess cable that needs to be gathered at one location (as shown in the illustration), dress the cable routed from both directions so that a single loop is left extending from the storage location. Doubling the cable up from this point, form the cable into a coil. Storing excess cable using this method can reduce electronic interference.
5. Connecting the Cable
Insert the transducer cable into the appropriate terminal slot. The cable
connectors are labeled, and there are corresponding labels on the cable holder
on the rear of the control head. The slots are keyed to prevent reversed
installation, so be careful not to force the connector into the holder. Refer
to your manual and/or control head installation guide for the correct
procedure for installing the cable connectors to the control head.
1. Plug the other end of the transducer cable back into the control head
connection holder.
Your control head is now ready for operation.
6. Test and Finish the Installation
Once you have installed both the control head and the transom transducer, and
have routed all the cables, you must perform a final test before locking the
transducer in place. Testing should be performed with the boat in the water,
although you can initially confirm basic operation with the boat out of the
water.
21
1. Press POWER once to turn the control head on. If the unit does not power
up, make sure that the connector holder is fully seated in the receptacle and
that power is available.
2. If all connections are correct and power is available, the Humminbird®
control head will enter Normal operation.
3. If the bottom is visible on-screen with a digital depth readout, the unit
is working properly. Make sure that the boat is in water greater than 2′ but
less than the depth capability of the unit, and that the transducer is fully
submerged, since the sonar signal cannot pass through air.
NOTE: The transducer must be submerged in water for reliable transducer
detection.
4. If the unit is working properly, gradually increase the boat speed to test
high-speed performance. If the unit functions well at low speeds, but begins
to skip or miss the bottom at higher speeds, the transducer requires
adjustment.
5. If you have the correct angle set on the transducer, yet lose a bottom
reading at high speed, adjust the height and the running angle in small
increments to give you the ideal transducer position for your boat. First,
adjust the height in small increment.
Transom Mount – DualBeam PLUSTM
NOTE: The deeper the transducer is in the water, the more likely that a
rooster tail of spray will be generated at high speeds, so make sure that the
transducer is as high as it can be and still be submerged in the water.
If you are still not getting good high speed readings, you may need to
disassemble the transducer mounting assembly and re-position the ratchets.
If you do change the transducer position, re-trace the position of the
mounting bracket before proceeding.
NOTE: It is often necessary to make several incremental transducer adjustments
before optimum high speed performance is achieved. Due to the wide variety of
boat hulls, however, it is not always possible to obtain high speed depth
readings.
6. Once you have reached a consistently good sonar signal at the desired
speeds, you are ready to lock down the transducer settings. Force the pivot to
the Up position to gain access to the mounting screws, then re-align the
mounting bracket against the transom of the boat to match the traced
silhouette. Check the bracket position with the level again to make sure it is
still level, then mark the third mounting hole using a pencil or marker.
Unscrew and remove the mounting screws and the transducer assembly and set
aside.
7. Drill the third mounting hole, using a 5/32″ drill bit. Use a marinegrade
silicone sealant to fill all three drilled mounting holes, especially if the
holes penetrated the transom wall.
NOTE: On fiberglass hulls, it is best to use progressively larger drill bits to reduce the chance of chipping or flaking the outer coating.
Fully Tighten All Three Mounting Screws
8. Re-position the transducer assembly against the transom of the boat, then hand-install all three screws. Make sure that the transducer location and the pivot angle have not changed, then fully tighten all three mounting screws. Snap the pivot back down. If you have performed the preceding procedures correctly, the transducer should be level and at the right height for optimal operation.

Locking Down the Transducer (Optional)
NOTE: You have the option to lock down the Two Piece Kick Up bracket if you do
not want the transducer to kick up. Please be aware, however, that the
transducer can be damaged if it is locked down and it strikes debris in the
water.

1. To lock down the transducer, trace the position of the mounting bracket. Force the pivot to the Up position to gain access to the mounting screws, then re-align the mounting bracket against the transom of the boat to match the traced silhouette. Check the bracket position with the level again to make sure it is still level, then mark the fourth mounting hole using a pencil or marker. Unscrew and remove the mounting screws and the transducer assembly and set aside.
2. Drill the fourth mounting hole, using a 9/64″ drill bit. Use a marine grade silicone sealant to fill all four drilled mounting holes, especially if the holes penetrate the transom wall.
Fully Tighten All Three Mounting Screws
3. Re-position the transducer assembly against the transom of the boat, then hand install the first three screws (two on the outside edges and one in the 3rd mounting hole). Make sure that the transducer location and the pivot angle have not changed, then fully tighten all three mounting screws. Hand tighten only!
4. Snap the pivot back down. Install #8 x 1″ wood screw into the 4th hole to lock down the pivot arm. Handtighten only!

Transom Mount – DualBeam PLUSTM
858c & 958c Inside the Hull Transducer Installation
DualBeam PLUSTM Transducer, XNT 9 20 T (858c and 958c only)
NOTE: Do NOT install the Side Imaging® transducer inside the hull, as the side
looking beams cannot penetrate the hull. Only the DualBeam PLUSTM transducer
can be mounted inside the hull.
If you choose to mount your transducer inside the hull of your boat, perform
the procedures in this section. In-hull mounting generally produces good
results in single thickness fiberglass-hulled boats. Humminbird® cannot
guarantee depth performance when transmitting and receiving through the hull
of the boat, since some signal loss occurs. The amount of loss depends on hull
construction and thickness, as well as the installation position and process.
This installation requires slow-cure two-part epoxy. Do not use silicone or
any other soft adhesive to install the transducer, as this material reduces
the sensitivity of the unit. Do not use five-minute epoxy, as it has a
tendency to cure before all the air bubbles can be purged, thus reducing
signal strength.
NOTE: In-hull mounting requires an installed and operational control head.
NOTE: Your transducer may not look exactly like the transducer shown in the
illustrations, but it will mount in exactly the same way.
There are several procedures you will have to perform in order to install a
transducer inside the hull. They are as follows:
· Locate transducer mounting location · Perform a trial installation · Route
the transducer cable · Permanently mount the transducer
1. Locating the transducer mounting location
Decide where to install the transducer on the inside of the hull. Consider the
following to find the best location:
· Observe the outside of the boat hull to find the areas that are mostly free
from turbulent water. Avoid ribs, strakes and other protrusions, as these
create turbulence.
· As a general rule, the faster the boat can travel, the further aft and
closer to the centerline of the hull the transducer has to be located in order
to remain in contact with the water at high speeds.
NOTE: The integral temperature probe will not work with in-hull mounting, so you may either want to consider purchasing a Temperature/Speed accessory, a Temp. Sensor, or obtaining a different transducer. Humminbird® offers a transducer exchange program to swap the NEW and UNASSEMBLED transducer, accompanied by mounting hardware, for one without an integral temperature probe. Call the Humminbird® Customer Resource Center at 1-800-633-1468 for details, or visit humminbird.com for more information.

2. Trial installation
You will not be able to adjust the mounting after an inside the hull
transducer is installed. It is best, therefore, to perform a trial
installation first that includes running the boat at various speeds, in order
to determine the best mounting area before permanently mounting the
transducer.
1. Plug the transducer into the control head, then power up the control head.
When the control head detects a functioning transducer, it will automatically
enter Normal operating mode.
2. View the sonar signal at its best by holding the transducer over the side,
immersed in the water, so that it is pointing straight down over a known flat
bottom. Use the display to benchmark against the sonar signal that will be
detected once the transducer is placed in the hull.
4. Fill the hull with enough water to submerge the transducer body. Use a
sand-filled bag or other heavy object to hold the transducer in position. The
transducer cannot transmit through air, and the water purges any air from
between the transducer and the hull, and fills any voids in the coarse
fiberglass surface.
5. View the sonar signal on the display and compare against what you observed
in Step 2, making sure that the boat is in the same location as it was during
your observations in Step 2. If the results are comparable, move on to Step 6.
Otherwise, locate a new position in the hull and repeat Steps 3 through 5.
25
Inside the Hull Mount – DualBeam PLUSTM
6. Run the boat at various speeds and water depths while observing the screen
on the control head. If depth performance is required, test the transducer in
water at the desired depth. If the performance is acceptable, move on to Step
7. If the performance is not acceptable, repeat Steps 3 through 6.
7. Once you have determined the best mounting location using the above steps,
mark the position of the transducer.
3. Routing the cable
1. Once the mounting location is determined and you have marked the position
of the transducer, route the cable from the transducer to the control head.
5. Coat the face of the transducer and the inside of the hull with epoxy.
4. Permanently mounting the transducer
1. Make sure the position of the transducer is marked.
2. You may have to disconnect the cable to the control head and reconnect it
at the end of this procedure.
3. Remove the water from inside the hull and thoroughly dry the mounting
surface. If the surface is excessively rough, it may be necessary to sand the
area to create a smooth mounting surface.
4. Slowly and thoroughly mix an ample quantity of two-part slow cure epoxy.
Avoid trapping air bubbles.
6. Press the transducer into place with a slight twisting motion to purge any
trapped air from underneath, keeping the end of the transducer that has the
mounting knuckle pointed forward, towards the bow of the boat.
NOTE: Proper operation requires the end of the transducer that has the
mounting knuckle to face towards the bow of the boat.
7. Weight the transducer so that it will not move while the epoxy is curing.
NOTE: When the epoxy cures, no water is necessary inside the hull.
8. If you unplugged the transducer cable at the beginning of this procedure,
plug it back into the control head.
NOTE: Neither water, spilled gasoline, nor oil will affect the performance of the transducer.

Side Imaging® Transducer, XHS 9 HDSI 180T (898c SI or 998c SI only)
In addition to the hardware supplied with your transducer, you will need a
powered hand drill and various drill bits, various hand tools, including a
ruler or straightedge, a marker or pencil, safety glasses and dust mask, and
marine-grade silicone sealant.
The Side Imaging® transducer has some special requirements because of its side
viewing capabilities:
· The Side Imaging® transducer must NOT have anything obstructing the `view’
of the side looking beams, i.e. nothing can be in the line of sight of these
beams (not a hull, motor, or other transducer, etc).
NOTE: You may need to tilt the motor up and out of the way when using the side
looking beams.
· In order for the side beams to be displayed accurately, the transducer must
be mounted so that it is looking straight down in the water when the boat is
in the water.
Transducer Mount Position
Unobstructed View: The jack plate gives the transducer safe distance from the motor and turbulence. The Side Imaging® has a clear view side-to-side.
Obstructed View: The transducer is too close to motor turbulence, and the Side Imaging® view is blocked by the motor. The view cannot extend from side-to- side.
NOTE: Due to the wide variety of hulls, only general instructions are presented in this installation guide. Each boat hull represents a unique set of requirements that should be evaluated prior to installation. It is important to read the instructions completely and understand the mounting guidelines before beginning installation.
NOTE: If the included transducer will not work for your application, you may
exchange it, NEW and UNASSEMBLED, with mounting hardware included, for a
transducer appropriate for your application – often at very little or no
charge depending on the transducer. Call the Humminbird® Customer Resource
Center at 1-800-633-1468 for details
and pricing, or visit humminbird.com.
NOTE: When drilling holes in fiberglass hulls, it is best to start with a
smaller bit and use progressively larger drill bits to reduce the chance of
chipping or flaking the outer coating.

Transom Mount – Side Imaging®
Overview
If you will be installing a Side Imaging® transom mounted transducer, use the
procedures in this section. There are two pieces to the transducer mount
assembly: the pivot, and the bracket. Your transducer comes with a two-piece
metal and plastic bracket assembly. There are several procedures you will have
to perform in order to install a transom-mounted transducer. They are:
· Determine transducer mounting location · Mount the bracket to the boat ·
Attach the pivot to the transducer · Mount the transducer pivot assembly to
the bracket · Adjust the running position of the transducer · Route the
transducer cable · Perform a final test of the transom transducer installation
Areas of Possible Turbulence
Stepped Hull
1. Locating the transducer mounting location
NOTE: If transom mounting is not possible because of a stepped hull or
cavitation noise, trolling motor installation may be an option. See Trolling
Motor Transducer Installation for more information.
1. First, determine the best location on the transom to install the
transducer. Consider the following to find the best location:
· It is very important to locate the transducer in an area which is relatively
free of turbulent water. As a boat moves through the water, turbulence is
generated by the weight of the boat, and the thrust of the propeller(s) –
either clockwise or counter-clockwise. This turbulent water is normally
confined to areas immediately aft of ribs, strakes or rows of rivets on the
bottom of the boat, and in the immediate area of the propeller(s). Clockwise
propellers create more turbulence on the port side. On outboard or
inboard/outboard boats, it is best to locate the transducer at least 15″ (380
mm) to the side of the propeller(s).

Transom Mount – Side Imaging®
Deadrise Angle
· The best way to locate turbulence-free water is to view the transom
while the boat is moving. This method is recommended if maximum
high-speed operation is a high priority. If this is not possible, select a
Rib
location on the transom where the hull forward of this location is
smooth, flat and free of protrusions or ribs.
28
· The hydrodynamic shape of your transducer allows it to point straight down
without deadrise adjustment.
· On boats with stepped hulls, it may be possible to mount the transducer on
the step. Do not mount the transducer on the transom behind a step to avoid
popping the transducer out of the water at higher speeds; the transducer must
remain in the water for the control head to maintain the sonar signal.
· If the transom is behind the propeller(s), it may be impossible to find an
area clear from turbulence, and a different mounting technique or transducer
type should be considered (see Trolling Motor Transducer Installation).
· The Side Imaging® transducer must NOT have anything obstructing the `view’
of the side looking beams, i.e. nothing can be in the line of sight of these
beams (not a hull, motor, or other transducer, etc).
Mounting the transducer bracket to the boat
1. Remove the transducer mounting template from this manual. See Appendix A
for the Transducer Mounting Template.
2. Hold the template on the transom of the boat in the location where the
transducer will be installed. Align the template vertically, matching the
lower edge of the transom with the bottom corner of the template. If your
propeller moves clockwise as the boat moves forward, mount the transducer on
the starboard side, and use the bottom left corner of the template. If your
propeller moves counterclockwise as the boat moves forward, mount the
transducer on the port side, and use the bottom right corner of the template.
3. Using a pencil or punch, mark the three mounting holes on the transom. Do
not mark or drill any other holes at this time.
4. Using a 5/32″ (4.0 mm) bit, drill the three holes to a depth of
approximately 1″ (25 mm). On fiberglass hulls, it is best to use progressively
larger drill bits to reduce the chance of chipping or flaking the outer
coating. Use a marine-grade silicone sealant to fill the drilled holes.

5. Align the metal mounting bracket with the mounting holes. The center slot should be above the two outer slots. (This bracket and all other hardware supplied is top quality stainless steel for maximum strength and corrosion protection.) Insert the three #10 – 1″ long screws into the drilled holes, but do not completely tighten.
Attaching the pivot to the transducer
1. Attach the pivot to the transducer body, using the two 1/4″-20 x 5/8″ (16
mm) machine screws, toothed washers, and square nuts. The toothed washers must
fit on the inside of the transducer ears, between the pivot and the ears. The
square nuts will be prevented from rotating by the pocket in the back of the
pivot. An Allen wrench is provided which fits all the 1/4″-20 screws, but do
not fully tighten the screws at this time.

Mounting the transducer pivot assembly to the bracket
1. Slide the assembled transducer into the metal bracket from the bottom,
aligning the large hole at the top of the bracket with the hole in the pivot.
2. Insert the headed pin through the pivot holes in the bracket and pivot.
The headed pin can be inserted from either side of the bracket.
3. Place the nylon washer over the opposite end of the headed pin. Place the
stainless washer over the 1/4″-20 x 5/8″ (16 mm) screw threads, then insert
into the opposite end of the headed pin and finger tighten only. The screw has
a thread locking compound on the threads to prevent loosening, and should not
be fully tightened until all adjustments are made.
NOTE: The running position of the transducer is now completely adjustable.
Subsequent adjustment may be necessary to tweak the installation after high
speed testing.

Adjusting the running position of the transducer
The transducer mounting bracket allows height and tilt adjustment, while the
pivot bolt allows angular adjustment. These adjustments will help reduce
cavitation. Initially, adjust the transducer as described in the following
paragraphs. Further adjustment may be necessary to refine the installation
after high-speed testing.
Normal Cavitation
Cavitation that will cause erratic sonar readings
1. First, adjust the pivot angle of the transducer body, so it is parallel
with the length of the hull of the boat.
2. Fully tighten the two pivot screws, using the supplied Allen wrench.
Access to the pivot screws is provided by the lower holes in the side of the
mounting bracket. It may be necessary to re-tighten the pivot bolt after
initial use as the plastic may still be conforming to the pressure from the
lock washers.
3. Adjust the height of the assembly so the face of the transducer is 1/8″ (3 mm) to 1/4″ (6 mm) beneath the bottom of the transom, and fully tighten the three mounting screws.
Tighten the Mounting Screws
4. In order to gain access to the mounting screws, the transducer assembly must be pivoted up in the bracket as shown. Be careful not to alter the running angle as some force is necessary to pivot the assembly.
5. If access to the top mounting hole is not possible due to the selected height of the transducer, fully tighten the two lower screws, then simply remove the headed pivot pin and the transducer assembly, and tighten the top screw, then reassemble.
6. Confirm that the pivot angle has not changed and that all mounting screws are fully tightened.
31
Transom Mount – Side Imaging®
Routing the cable
The transducer cable has a low profile connector that must be routed to the
point where the control head is mounted. There are several ways to route the
transducer cable to the area where the control head will be installed. The
most common procedure routes the cable through the transom into the boat.
NOTE: Your boat may have a pre-existing wiring channel or conduit that you can
use for the transducer cable.
1. Unplug the other end of the transducer cable from the control head. Make
sure that the cable is long enough to accommodate the planned route by running
the cable over the transom.
CAUTION! Do not cut or shorten the transducer cable, and try not to damage the
cable insulation. Route the cable as far as possible from any VHF radio
antenna cables or tachometer cables to reduce the possibility of interference.
If the cable is too short, extension cables are available to extend the
transducer cable up to a total of 50′ (15 m). For assistance, contact the
Customer Resource Center at humminbird.com or call
1-800-633-1468 for more information.
NOTE: Since the transducer may need to pivot up to 90° in the bracket if it
strikes an object, make sure there is sufficient cable slack to accommodate
this motion. It is best to route the cable to the side of the transducer so
the cable will not be damaged by the rotation of the transducer.
2. If you will be routing the cable through a hole in the transom, drill a
5/8″ diameter (16 mm) hole above the waterline. Route the cable through this
hole, then fill the hole with marine-grade silicone sealant and proceed to the
next step immediately.
Routing the Cable 5/8″ Hole
Escutcheon Plate
Cable Clamp
3. Place the escutcheon plate over the cable hole and use it as a guide to
mark the two escutcheon plate mounting holes. Remove the plate, drill two
9/64″ (3.5 mm) holes, then fill both holes with marinegrade silicone sealant.
Place the escutcheon plate over the cable hole and attach with two #8 x 5/8″
(16 mm) wood screws.
4. Route and secure the cable by attaching the cable clamp to the transom;
drill one 9/64″ dia. (3.5 mm) x 5/8″ deep (16 mm) hole, then fill hole with
marine-grade silicone sealant, then attach the cable clamp using a #8 x 5/8″
(16 mm) screw.
5. Plug the other end of the transducer cable back into the control head
connection holder.
Testing the installation
After transom transducer installation, please perform the final testing and
then finalize the installation (see Test and Finish the Transducer
Installation).
Transom Mount – Side Imaging®

Trolling Motor Transducer Installation
Several styles of the transducer are compatible with trolling motor mounting.
If you have a trolling motor bracket, refer to the separate installation
instructions that are included with the bracket.
NOTE: After trolling motor transducer installation, please perform the final
testing and then finalize the installation (see Test and Finish the Transducer
Installation).
Trolling Motor Transducer Options
If you don’t have a trolling motor transducer, there are several options:
· You may purchase a Trolling Motor Adapter kit that will allow you to mount
the transducer on the trolling motor.
· You may also exchange your NEW and UNASSEMBLED transducer (with mounting
hardware included) for a trolling motor transducer.
There are also several transducer switches available that support the
following configurations:
· Two control heads with one transducer · Two transducers with one control
head.
NOTE: Call the Humminbird® Customer Resource Center
1-800-633-1468 for details and pricing,
or visit humminbird.com for more information.
Test and Finish the Transducer Installation
When you have installed both the control head, the transducer, and
accessories, and have routed all the cables, you must perform a final test
before locking the transducer in place. Testing should be performed with the
boat in the water, although you can initially confirm basic operation with the
boat out of the water.
1. Press the POWER/LIGHT key once to turn the control head on. There will be
an audible chirp when the key is pressed correctly. If the unit does not
power-up, make sure that the connector holder is fully seated and that power
is available.
2. If all connections are correct and power is available, the control head
will enter Normal operation. If no transducer is detected (or one is not
connected), the unit will go into Simulator mode and will indicate this by
displaying the word Simulator on the control head display.
NOTE: The transducer must be submerged in water for reliable transducer
detection.
3. If the bottom is visible on-screen with a digital depth readout, the unit
is working properly. Make sure that the boat is in water greater than 2 ft (.6
m) but less than the depth capability of the unit, and that the transducer is
fully submerged, since the sonar signal cannot pass through air.
33
Test & Finish Transducer Installation
4. If the unit is working properly, gradually increase the boat speed to test
high-speed performance. If the unit functions well at low speeds but begins to
skip or miss the bottom at higher speeds, the transducer requires adjustment.
Angling the rear of the transducer downward and/or lowering the transducer
farther into the water will help achieve depth readings at high speeds. If the
left side of the fish arch is longer than the right side, then the back of the
transducer is angled too far downward. If the right side of the fish arch is
longer than the left side, then the back of the transducer is angled too far
upwards.
NOTE: It may not always be possible to get symmetrical fish arches and high
speed depth readings at the same time. Due to the wide variety of boat hulls,
however, it is not always possible to obtain high speed depth readings.
NOTE: It is often necessary to make several incremental transducer adjustments
before optimum high speed performance is achieved.
Once you have reached a consistently good sonar signal at the desired speeds,
you are ready to lock down the transducer settings.
5. Mark the transducer bracket location on the transom with a pencil, then
pop up the bracket to reveal the mounting screws. Tighten the stainless steel
mounting bracket screws to secure in place. Hand-tighten only!

Follow these steps to stem mount the GPS receiver:
NOTE: If you have an existing stem for mounting the GPS receiver, proceed
directly to step 2 of the following procedure.
1. Determine the best location to mount your GPS receiver. Preplan and test
the cable routing to your control head before any drilling or cutting of your
boat surfaces. If you have purchased hardware to stem mount your GPS receiver,
follow the instructions included with that hardware to mount the stem (antenna
pole).
3. Use electrical tape to secure the NMEA pigtail to the cable as shown.
NOTE: Leave the NMEA pigtail secured to the cable unless needed. This will
make removing the receiver easier.
4. Route the GPS receiver cable through the stem and continue with the
planned route you chose in step 1.
5. Attach the GPS receiver to its base using the included #6 – 7/8″ screws.
NOTE: AS-EC10 10′ extension cables are available from Humminbird® if your
planned routing exceeds 20′, (6 m). Maximum cable length, including

Testing the System Installation
After you have completed the installation of the control head, transducer, and
any other accessories such as the GPS receiver, and have made all the cabling
connections required, you must test the installation before using the system.
Thorough testing should be performed with the boat in the water; however, you
can confirm basic operation initially with the boat out of the water as well.
To test the installation:

2 Timer – Elapsed time with Speed accessory or GPS Receiver. 3 Distance –
Distance traveled with Speed accessory or GPS Receiver. 4 Average Speed –
Average speed reading with Speed accessory or GPS Receiver.
10 Bait Ball
11 RTSTM (Real Time Sonar) Window
12 Second Sonar Return – When the sonar
signal bounces between the bottom and the
surface of the water and back again. Use
11
the appearance of the second return to determine bottom hardness. Hard bottoms
will show a strong second return, while soft
bottoms will show a very weak one or none
at all.
5 Barometric Pressure – Requires optional-purchase WeatherSense®

What’s on the Sonar Display
Triplog
Understanding the Sonar Display
It is important to understand the significance of the display. The display
does NOT show a literal 3-dimensional representation of what is under the
water. Each vertical band of data received by the control head and plotted on
the display represents something that was detected by a sonar return at a
particular time. As both the boat and the targets (fish) may be moving, the
returns are only showing a particular segment of time when objects were
detected, not exactly where those objects are in relation to other objects
shown on the display.
The returned sonar echoes are displayed on the screen. As a new echo is
received, the historical data scrolls left across the display.
Real Time Sonar (RTSTM) Window
A Real Time Sonar (RTSTM) Window appears on the right side of the display in
the Sonar View only. The RTSTM Window always updates at the fastest rate
possible for depth conditions and shows only the returns from the bottom,
structure and fish that are within the transducer beam. The RTSTM Window plots
the depth and intensity of a sonar return. (See Sonar Menu Tab: Real Time
Sonar (RTSTM) Window).
The Narrow RTSTM Window indicates the sonar intensity through the use of colors. Red indicates a strong return and blue indicates a weak return. The depth of the sonar return is indicated by the vertical placement of the return on the display depth scale.
The Wide RTSTM Window indicates the sonar intensity through the use of a bar graph. The length of the plotted return provides an indication of whether the return is weak or strong. The depth of the sonar return is indicated by the vertical placement of the return on the display depth scale.
SwitchFireTM
SwitchFireTM controls how the sonar returns are displayed in the Sonar Views.
SwitchFireTM settings are available in the Sonar Menu Tab.
To see the maximum sonar information available within the transducer beam so more fish arches and better jig tracking are shown, choose Max Mode.
To see less clutter and more fish size accuracy interpreted from the transducer beam, choose Clear Mode. See Sonar Menu Tab: SwitchFireTM for more information.
What’s on the Sonar Display
46
Freeze Frame and Active Cursor
Freeze Frame & Active Cursor – Press any arrow on the 4-WAY Cursor Control
key, and the screen will freeze and a cursor will be displayed. Use the 4-WAY
Cursor Control key to move the cursor over a sonar return, and the depth of
the sonar return will be displayed at the top of the screen in the cursor
dialog box.
The RTS WindowTM continues to update in Freeze Frame. To return to a scrolling
display and exit Freeze Frame, press the EXIT key. Freeze Frame is available
in the Sonar, Split Sonar, and Sonar Zoom Views.
The sonar returns from the bottom, structure, and fish can be represented as
Structure ID® or WhiteLineTM. See Sonar Menu: Bottom View to set the Bottom
View.
Structure ID® represents weak returns in blue and strong returns in red.
Instant Image Update
Instant Image Update – You can change a variety of sonar menu settings (such
as Sensitivity or Upper Range), and the adjustments will be shown instantly on
the screen.
Sonar Bottom Presentation
As the boat moves, the unit charts the changes in depth on the display to
create a profile of the Bottom Contour. The type of bottom can be determined
from the return charted on the display. A Hard Bottom such as compacted
sediment or flat rock appears as a thinner line across the display. A Soft
Bottom such as mud or sand appears as a thicker line across the display. Rocky
Bottoms have a broken, random appearance.
NOTE: A sloping bottom will be represented as a thicker line across the
display. Harder bottoms typically will be displayed with red and softer
bottoms typically will be displayed with blue.
WhiteLineTM highlights the strongest sonar returns in white, resulting in a distinctive outline. This has the benefit of clearly defining the bottom on the display.
47
What’s on the Sonar Display
What’s on the Side Imaging® Display (898c SI and 998c SI only)
Side Imaging® displays a number of easily recognizable features that allow for accurate interpretation of bottom contour and structure. For Side Imaging®, the bottom composition determines the intensity of the sonar return. For example, rock and gravel provide a clearer sonar return than mud and sand because of their relative density. Upward slopes that face the transducer reflect sonar better than downward slopes that face away from the transducer. You can find a number of easily recognizable features on the Side Imaging® display that allow for accurate interpretation of bottom contour and structure, including the following items:
Triplog

5 6
8 Water column – Shows the relative depth of the water under
the boat at a given time. Variations in the width of the water
column show variations in the distance to the bottom as the
13
12
boat passes over.
9 Shadows – Result from a lack of reflected sonar from a particular area and
can be more valuable for interpretation than the sonar
reflected by the object itself. Use shadows to help you see the
10
image in 3 dimensions, oriented in space. You can gain insight into the actual shape of an object, or the depth to which it has
9
sunk into the bottom, through shadows on the display. Objects
standing on the bottom cast a sonar shadow. The longer the
11
shadow, the taller the object. Fish also cast shadows. You can
use the shadow to interpret how close the fish is to the bottom.
15

keep a triplog of nautical or statute miles traveled.
12 Side Imaging® Range – Images shown on the right side of the screen are
located on the right side of your boat, and images shown on the left side of
the screen are located on the left side of your boat. In this illustration,
the sonar is pinging 148 feet on each side.
13 Top of the Display – Information from the side beams are displayed at the
top of the screen. As new information is received, the historical data scrolls
down the screen. For the most current information, watch the top of the
screen.
14 Freeze Frame & Zoom – Use the 4-WAY Cursor Control key to move the cursor
to an area on the screen, and press the ZOOM+ key to see the sonar returns in
greater detail.
15 Clouded Area – May indicate a bait ball and White Streaks may indicate
fish.

What’s on the Side Imaging® Display
48
Understanding the Side Imaging® Display
It is important to understand how Side Imaging® technology produces the
display. The images you see on the display are produced using sonar
technology. The special transducer projects three distinct beams one beam
facing down and two beams pointing out to the side.
Down Beam is aimed directly below the boat and provides conical coverage.
Side Beams are aimed at right angles to the path of the boat. The side beam
coverage is very thin from front to back, yet very wide top to bottom. The
narrow aspect (front to back) of the beam illuminates a small strip of the
bottom perpendicular to the direction of t
