INTRODUCTION
Congratulations on purchasing the MarCum Digital Sonar—the most advanced ice
sonar system available. When MarCum was founded over a decade ago, we all knew
that our original flashers were just the beginning. Every step of the way, we
have been designing, improving, building momentum. This momentum keeps us in
nearly perpetual motion, on the Vanguard of innovation, with our competition
forever in our rear-view mirror. We’re glad you’ve joined us in the front
seat. While our existing product lines have always beat the competition in
every category, up until now there has always been room for lively discussion
as to the merits of various systems. These discussions will now come to a stop
as we usher in a new era in ice fishing electronics: The MarCum Digital Sonar.
These units are the most advanced ice fishing sonars ever designed, and now
that you own one you’re about to see why.
With a customizable dashboard display, superior target separation, 12-level
interference rejection, dual-beam transducer, adjustable zoom, and much more,
the MarCum Digital Sonar is the perfect combination of macro features and
micro precision.

GETTING STARTED
Ice System Set-Up
Your Digital Sonar comes virtually ready to fish. Open the top cover of the
soft pack, loosen the knobs and the monitor can now be positioned how you want
it. Once the monitor is positioned, tighten the knobs again to hold the
monitor in place.
Look behind the monitor and hook up the Digital Sonar’s power cord to the
battery. While you are at it, remove the entire unit from the soft pack so you
can see exactly how everything connects—this makes it easier down the road if
you ever need to change a battery or transducer.
Your Digital Sonar is delivered with a 9-amp battery that is charged, so you
can take it fishing right away. Even though the battery comes with a charge on
it, due to storage time or other factors it may not be fully charged when you
get it, so if you are not going fishing immediately you should hook up the
charger to make sure the battery has a full charge.
To charge the battery, see below. The MarCum Digital Sonar will operate for 10
hours or more on a fully charged battery. If you are going to be in a
situation where you will want to use your system for more than one day without
recharging, having a second, fully charged battery with you is cheap insurance
that will allow you to get full use out of your system for the duration of
your trip. Inside the MarCum Digital Sonar’s soft case is an electronics
shuttle that has compartments for the battery and the dual beam transducer, as
well as a transducer arm. The adjustable transducer arm allows for maximum
flexibility in positioning the Digital Sonar around the ice hole, and can even
be moved to the other side of the shuttle.
Using the MarCum Digital Sonar can be as simple as turning it on—the factory
settings will come on automatically and allow you to use the Digital Sonar in
the most popular configuration. Be sure to explore all the options available
to customize your Dashboard Display. With five different sonar portals, four
color palettes, two cone angles, and a myriad of other settings, there are
many possibilities. Changing your settings is easily done on the fly, but
experimenting while using the simulator at home will help you learn the “flow”
of the menu and settings.
Battery Charging
Your MarCum system comes with a 3-stage battery charger. This style of charger
has proven to be the most effective and easiest to use of all charging systems
available. Because this is a 3-stage charger, there is no danger of
overcharging your battery. When properly cared for, a sealed lead acid battery
will last for at least a couple of years. Batteries are made to be used, and
they need to be used to make the most of them. The most important thing you
can do is to promptly recharge your battery after each use. Not charging your
battery immediately after use is the number one thing that leads to battery
failure.
For safety reasons, it is recommended that you place your system on a flat,
hard surface like cement or tile when charging it, away from any flammable
materials. Be sure to disconnect the charger from the wall when not in use,
and avoid leaving your battery hooked up to the charger for extended periods
of time.
When you get home from a trip, put your battery on charge right away and leave
it there overnight, or for around 8-12 hours. Likewise, on the night before an
ice fishing trip, put it on the charger again to ensure a charge. Again, there
is no danger of overcharging your battery. We often talk to people who
hesitate to charge their battery after each use for fear that the battery will
develop a “memory” and this will lead to a shortened run time—THIS IS FALSE!!!
ALWAYS CHARGE YOUR BATTERY AFTER EVERY USE!!! Be sure, to use the charger that
came with your system, or a similar one that is between .5 amp. and 1 amp.
Using a larger charger, like you would use on a car, truck, RV, or boat is
likely to cause damage to the battery. There is really no danger of
overcharging your battery with a low amp charger, and most chargers
automatically go into “maintenance mode” once a full charge has been achieved.
TO CHARGE YOUR BATTERY:
Your battery has a wiring harness attached to it that has “piggyback”
terminals on it, enabling you to keep the power cord from the unit attached to
the battery always, as well as having the wiring harness with receptacle for
your charger attached always. To charge, simply couple the end of the charger
with the end of the wiring harness. It is normal for a green light to appear
on the charger now if the charger is plugged into the battery only. It is also
normal for the light on the charger to be green if it is just plugged into the
wall. When it is plugged into the wall and battery, you will see a red LED
light appear on the charger. If the light is red, the battery is being
charged. When your battery is fully charged, this red light should change to
green. If it is time to go fishing and the light has not turned green, go fish
and try to allow a longer charging period next time.
Batteries are an expendable item, and must be replaced periodically. The
batteries that we use are the “Sealed Lead Acid” variety, they are 12 volts,
and range from 7 to 9 amps. The more amps the battery has, the longer it will
run on a full charge. Your Marcum can be powered off any battery that is 12
volts, even a large automotive or deep cycle battery. If you are having
difficulty with the charging process, please see the Charger Troubleshooting
section at end of the manual.
If you need to remove the battery, slide the power cord leads from the
battery. Remove the strap that is holding the battery in place and lift the
battery out.
To replace the battery, place a new battery of similar specifications into the
battery compartment and secure it with the Velcro strap and re-connect the
positive and negative terminals.
SETTING THE TRANSDUCER FOR ICE FISHING
When used in conjunction with the retractable pivoting transducer arm and
rubber stopper, the Digital Sonar’s transducer will automatically level itself
in your ice hole. To begin operation, take the transducer out of the recessed
holder, and rotate the adjustable ice arm out from inside the shuttle. Extend
the transducer arm, (the cable should already be threaded through it with
stopper in place) and deploy the transducer into the water. We recommend
setting your stopper to have the transducer down the least amount possible.
The MarCum Digital Sonar puts out enough power that in most cases it is not
necessary to have your transducer down more than a few inches below the water
line to get a good reading. When the ice thickness is over two feet, it may be
necessary to have your transducer set somewhat farther down.
Remember–the less transducer cable you have out, the easier it is to pull it
out of the water when bringing in a fish, or to move to a new location. Under
no circumstances should you ever have the ducer below the ice—this can lead to
the ducer becoming damaged.
It is also important that you keep the cable near the center of the ice hole.
We frequently hear from anglers who allowed their cable to freeze into the
side of the ice hole. If this should happen to you, make sure the unit is
turned off before attempting to chisel it out. If you accidentally cut the
ducer cable, do not try to use that ducer again.
MOVING THE DUCER TO A NEW LOCATION
Being mobile is one of the keys to being successful on the ice. Whenever you move from one spot to another, it is tempting to leave your transducer hanging on the transducer arm. This is likely to lead to failure of the transducer arm, and can cause damage to the transducer itself. Always stow the transducer inside the pack when you are moving. Keeping the amount of transducer cord you have out at a minimum will make transporting your Digital Sonar easier. Similarly, you may need to quickly remove your transducer from the hole when about to land a fish. We have seen anglers in a panic grab the shuttle itself and toss the entire unit to the side. This is no way to treat any piece of electronics; a much better approach is to simply lift the transducer out of your way by the cord, and the shuttle itself can be gently pushed aside. Whenever you are moving via sled or vehicle, always fold up your transducer arm, stow the transducer inside, and close the protective soft pack.
READING THROUGH ICE
The MarCum Digital Sonar will provide accurate information reading through ice providing the ice is reasonably clear. Wet the ice with at least a cup of water to improve the coupling of the transducer to the ice. Place the face of the transducer firmly on the wetted ice, and you will now be able to see the depth displayed digitally, and a signal showing the bottom (and fish) on whichever sonar windows you have open. Drilling into the ice 1-2” before taking a reading may be necessary if the surface of the ice is very rough, or if the ice is filled with air bubbles.
OPERATION
The MarCum Digital Sonar has many functions and settings that are selected or
changed by buttons on the Control Panel. Learning what each of the buttons
(POWER, SENS, RANGE,
ZOOM, IR, CONEANGLE, TARGET ADJUST, MENU/ENTER, UP, DOWN) does will enable you
to get the most out of your Digital Sonar. Note that you can experiment with
different settings and dashboard arrangements in SIMULATOR mode. Many of the
selections will activate just by highlighting your desired setting.
CONTROL PANEL
The following is an explanation of each button on the control panel and what
it does. Some of the button functions can also be accessed in the main menu.
Pressing any of the Control Panel buttons will cause a window to open,
enabling the user to make the desired adjustments. All button function windows
will time out after about 6 seconds. Any changes made to the settings will
activate when the MENU button is pressed, or after a few seconds without
activity.
POWER – Press and hold this button for 2 seconds to turn your unit on or off.
SENS – The SENS (sensitivity) button controls the amount of sensitivity
required by the unit to pick up objects like bottom, weeds, fish, or lures and
jigs. The lower the number, the less sensitivity, conversely higher numbers
mean more sensitivity. To adjust your sensitivity, first press the SENS button
and a bar will appear at the bottom of your display. Pressing the UP/ DOWN
will adjust your sensitivity, and the sensitivity setting will now be
digitally displayed on the SENS gauge. The best SENS setting is achieved by
turning up your sensitivity until you receive a clear and steady bottom
reading. To see your lure or bait, turn up the SENS some more until you just
begin to display your bait without it fading or flickering on the screen. The
sensitivity will go up to 25, but you are likely to have it set considerably
lower.
RANGE – The MarCum Digital Sonar has nine different fixed ranges, as well as
the ability to create custom ranges using the Dynamic Depth feature. Pressing
the RANGE button on your Digital Sonar will open a sub-menu with four
different range options.
AUTO RANGE – Selecting AUTO will put the Digital Sonar into a sort of “search
mode” where it will detect the bottom and automatically lock into one of the
nine ranges [10, 20, 40, 60, 80, 120, 180, 240, and 300]. This is a feature
that allows you to simply turn on the unit and begin fishing.
To enter Auto Range, press RANGE, and use the UP button to highlight “Auto”,
and the Digital Sonar will automatically lock into the appropriate depth
range. For instance, in 32 feet of water, the Digital Sonar will lock into the
40-foot range. In 45 feet of water the Digital Sonar will automatically lock
into the 60-foot range.
MANUAL RANGE – Selecting MANUAL will allow the user to decide which fixed
range they would like to have displayed. Highlight MANUAL, and arrow up or
down to the desired depth range.
DYNAMIC – This MarCum exclusive feature functions similarly to the “Auto
Range”, but fine tunes your range setting even farther. The Dynamic Depth will
maximize the space on your display by utilizing a variable range that will
always be just slightly deeper than the actual depth. For example, if you were
fishing in 23 feet of water, the Dynamic Depth feature will automatically
create a custom range of 0 – 25 feet. Similarly, if you were in 29 feet of
water, the Dynamic Depth range will be 32 feet. The Dynamic Depth range will
not go shallower than 10 feet.
MANUAL DYNAMIC – This functions similarly to the DYNAMIC DEPTH, but allows the
user to select the depth range. For instance, say you start out in AUTO range
and you quickly learn that the water is 21 feet deep. The AUTO range will have
selected the 0-40 foot range. To fine tune your display, press the RANGE
button, and highlight MANUAL DYNAMIC. Now start pressing the UP/DOWN buttons
to get to the desired DYNAMIC DEPTH range. If the water is 21 feet deep, you
would select 22 feet. Now the DYNAMIC DEPTH has created a 0 – 22 foot range,
utilizing virtually 100% of your display.
We offer the manual range functions because in some circumstances the AUTO
range functions can behave erratically. In situations where there is heavy
weed growth, uneven bottom contours, or very shallow water, it is suggested
that the user manually selects a fixed depth range.
ZOOM – The ZOOM button allows you to select the upper range of the portion of
the water column you would like to zoom in on. The actual size of the Zoom
window can be adjusted in the Main Menu.The Zoom feature allows you to focus
the display on a specific depth within the water column, and can be a great
benefit in a variety of fishing situations. See the separate ZOOM section
below for more info on the ZOOM. Whenever you are utilizing the ZOOM menu,
keep in mind that it “times-out” after 6 seconds.
IR (INTERFERENCE REJECTION) – The Interference Rejection system is designed to
suppress competing return signals from other sonar units being used within
proximity. When other sonar units are causing interference to the display of
the Digital Sonar, activate the IR feature by depressing the IR button located
on the control panel of the Digital Sonar. Interference is indicated by
unusual signals flashing or scrolling across your display.
There are 12 levels, or channels, of interference rejection. Press the IR
button once to open the IR window, now use the UP/DOWN buttons to select the
desired level of IR. The correct level of IR will be achieved when the display
is clear of display clutter. In some extreme cases, clutter will be greatly
reduced but not eliminated. Anytime two or more sonars are being operated in
proximity to each other, there is the potential for interference. Deep water
and hard bottom will increase the likelihood that one or more of the competing
sonars will experience interference. Besides experimenting with different
levels of IR, the anglers experiencing interference can also try having their
transducers set at different levels, going to narrow cone angles, and reducing
gain or sensitivity settings.
CONE ANGLE – All transducers send down a signal that is shaped somewhat like a
cone. Your Digital Sonar easily switches from a 20-degree cone angle (good for
general use) to a narrow 8-degree cone angle (good for water over 40’, or any
time you need a more precise view of what is below you). See the special
section on Cone Angles below for more info. A feature unique to the Marcum
Digital Sonar is the “Sonar Footprint” that displays the actual extent of
coverage by your transducer while you are fishing. This data is displayed
below the cone angle icon, and represents the diameter of the base of the
transducer cone. This will keep you constantly updated how much area is being
covered by your Digital Sonar, and will help you decide which transducer angle
best suits the conditions.
When the MarCum Digital Sonar is first turned on, it will be transmitting
utilizing the 20-degree setting. To switch from 20 degree to 8 degree, simply
press the CONE ANGLE button once and use the UP/DOWN buttons to highlight the
desired selection. The cone angle changes as soon as you highlight a selection
and the Sonar Footprint will change with it.
TARGET ADJUST – This feature allows the angler to change the size of the
signals being displayed without increasing the sensitivity. The TARGET ADJUST
feature will give you the smallest, signal size at “0”, and the signals
displayed will get thicker as you increase the TARGET ADJUST. This feature
should be used in conjunction with the SENS to fine-tune your display. Those
who have a hard time seeing, as well as those who fish from a standing
position will really appreciate the “TARGET ADJUST” feature.
BATTERY METER — This gauge indicates the voltage currently being produced by
your battery. The Marcum Digital Sonar needs at least 11 volts and preferably
over 12 volts to properly operate. If the voltage drops below 11 volts, you
may see a decrease in performance. Recharging your battery after each use will
maximize the life of your battery, and will ensure that your Digital Sonar
will run strong all day.
MENU/ENTER— This button enables you to access other functions of the Digital
Sonar. Some of these functions are also accessible using the other buttons on
the Control Panel. When you press the MENU button, three sub-menus will be
revealed—SONAR SETTINGS, DISPLAY OPTIONS, and SYSTEM SETTINGS.
Use the arrow buttons to highlight the desired sub-menu, and press MENU again
to access to the sub-menu
SONAR SETTINGS is the first sub-menu, and it has the following features that may be adjusted:
SENSITIVITY| This adjusts the sensitivity. This is described in the
Control Panel section above
---|---
RANGE| Select range in the same manner as described above
ZOOM DEPTH| Here is where you set the upper range of the zoom window.
This can also be done by using the ZOOM button as described above. The actual
size of the zoom window is adjusted in the “Zoom Window” field.
ZOOM WINDOW| Here is where you determine the size of the ZoomWindow. Go
to the “Zoom” section of the manual for more specific information.
IR| Interference Rejection can be adjusted here, as well as by using the
Control Panel button. See above for more info.
TARGET ADJUST| Target Adjust can be adjusted here, as well as by using
the Control Panel button. See above for more info.
CONE ANGLE| Cone Angle [and Sonar Footprint] can be adjusted here, as
well as by using the Control Panel button. See above for more info.
SONAR MODE| Choose between “Gain 1” and “Gain2” mode here. NOTE— when
ice fishing in shallow water [10′ or less], you may have better performance if
you select “Gain 2”
MAX PING RATE| Adjusting this setting will increase the response time of
signals from your transducer to the screen. If fishing shallow water (less
than 20 feet) use the lower settings. Likewise, you will see better
performance with the higher settings in deeper water.
TRANSDUCER OFFSET| This will allow you to have true a depth measurement,
no matter how far below the water line you have your transducer. If you have
your transducer 8 inches below the water line, but want a true depth reading,
select “Transducer Offset”, and use the DOWN button to highlight 8 inches. You
will notice your sonar signals will shift to reflect this offset. This
function is particularly useful if using your Digital Sonar on a boat, where
you will have your ducer [open water “Universal Ducer” sold separately]
mounted well below the waterline somewhere on your boat.
DISPLAY OPTIONS is the second sub-menu, and it has the following features that may be adjusted
FLASHER DISPLAY | The Flasher Display can be turned on or off here |
---|---|
VERTICAL DISPLAY | The Vertical Display can be turned on or off here |
VERTICAL ZOOM DISPLAY | The Vertical Zoom Display can be turned on or off |
here
CHART DISPLAY| The Chart, or Scrolling graph, can be turned on or off
here
CHART ZOOM| This enables you to use the scrolling graph in zoom mode
GAUGE DISPLAY| Your 5 gauges, as well as your Sonar footprint may be
turned on or off here
TEMPERATURE| Your water temperature display may be turned on or off
here. You may also select between Fahrenheit and Celsius here. This feature
will only work if you are using your unit with the optional “Universal Sonar”,
designed for open water use.
BACKLIGHT| You can adjust the overall brightness level of the display
here.
When using outside during bright conditions, you will want to have it set
fairly high, at 50 or more. In low light or when using inside an ice shack, a
setting of 50 or less is desirable.
COLOR PALETTE| There are four different color palettes; you choose which
one you prefer here. See the section below on Color Palettes below for more
info.
BACKGROUND| There are three different backgrounds; you choose which one
you prefer here. The “Night” option is great for low light periods or when in
a darkened shack.
SYSTEMS SETTINGS is the third sub-menu, and it has the following features that may be adjusted
LANGUAGE | Choose between English or French |
---|---|
UNITS | Choose between feet or meters |
SIMULATOR | The Digital Sonar has a simulator mode that will portray a |
variety of different depths and signal returns. Activating this feature
enables the user to experiment with the various settings without actually
being on the water. This simulator represents an open water or ice fishing
experience, so the depths and signals will change as it goes through the
simulation.
RESTORE FACTORY| This is where you can restore factory settings. The
factory settings are the most popular configuration, and if at any time of
changing your selections you want to revert back to this screen, you may
easily do so here.
RESTORE SAVED| If you find a screen configuration that you like, you can
easily return to that saved screen by highlighting this selection
COLOR PALETTES — The default setting is the 6-color palette. This setting
has RED representing the strongest signal, often signifying a hard bottom or a
larger fish that is in the center of the transmit signal (cone). As signal
strengths diminish, the colors will fade accordingly.
Again, red represents the strongest signal, followed by orange, yellow, light
green, green, and blue. When using the other color palettes, the colors
displayed and the signal strengths represented will change accordingly. It is
impossible to always associate a particular type of signal from a target with
a particular color, as water depth, sensitivity setting, and the target’s
proximity to your location can all affect how the signals show on your
display.
SIMULATOR — The MarCum Digital Sonar has a simulator mode that will
portray a variety of different depths and signal returns. Activating this
feature enables the user to experiment with the various settings without being
on the water. This simulator represents an open water or ice fishing
experience, so the depths and signals will change as it goes through the
simulation.
When using your Digital Sonar in open water [in a moving boat] it is typical
to mark fish as a “hook” or “arch” shape. When stationary, as in ice fishing,
your signals of both your jig and the fish will show as lines of varying
thicknesses.
You may also experiment with settings by getting your Digital Sonar to get a
bottom reading off the floor in your house or garage. It must be a bare tile
or cement floor. Position your Digital Sonar with the transducer hanging
motionless about 2 feet above the tile or cement floor and then turn the
sensitivity up to the maximum [25] setting. If the ducer is 2 feet above the
floor, you should get a bottom reading at about 8.5 feet [the unit is
calibrated to be accurate in water, not air!]. If you now raise and lower the
ducer, the bottom signal should move in a corresponding manner. You may find
it is easier to learn the zoom and other functions while experimenting in this
way with the “manual simulator”.
GAUGES — A feature unique to the MarCum Digital Sonar is the ability to
be able to constantly see where your most critical settings are at. At a
glance, you will be able to see what your sensitivity level is, what level of
IR you are operating at, how high your Target Adjust is, your range, and
battery status displayed in volts. The gauges can be turned on or off by
pressing MENU, highlighting “Gauge Display”, and making your selection. Where
the gauges display will depend on which screen configuration you have
selected.
ZOOM INFO
One of the best features to have in an ice fishing Sonar is a “Zoom”, and
there is none better than that of the Marcum Digital Sonar. A Zoom feature
enables you to have a magnified view of a selected portion of the water
column. Note that when the ZOOM window is open, you can still view the entire
water column on one of the other windows. Imagine that you are fishing for
walleyes in 30 feet of water, and you are zoomed in on the bottom 5 feet. If a
school of crappies comes through at 20 feet, you will be able to easily see
them on one of the other windows, and quickly raise your bait to their level.
The position of the ZOOM window is adjustable in one-foot increments, and can
be moved to focus on the bottom (for detecting bottom-hugging fish), or at any
level above bottom for suspended fish.
The MarCum Digital Sonar also offers Auto Bottom Lock Zoom that automatically
zooms and locks onto the bottom, even when you change locations. This is
especially useful for if you are hole-hopping for bottom hugging fish like
walleyes and perch. To access the Auto Bottom Lock Zoom, press ZOOM, and then
press the UP button until “A” (Auto) appears. It will appear after you pass
“0” on the Zoom Window. The ZOOM feature on the MarCum Digital Sonar can be
accessed in several ways depending on which sonar windows you have displayed
on your dashboard. Having your Digital Sonar set at the factory default
setting for a screen configuration will make it easiest to learn how to use
the Zoom. It is highly recommended that you learn how the Zoom works while in
simulator mode.
Operating the Zoom is quite simple, and only requires the pressing of a few
buttons to select the size and position of your Zoom window.
Begin from the factory default screen open (Flasher in center, Vertical
Display on left, Vertical Zoom on right). The area that is featured on the
Zoom Display is indicated by the “Zoom Indicator Bar”, a light blue bar on the
right side of the Vertical Display. When you press the ZOOM button, a “Zoom
Depth” window will appear at the bottom of the screen. This is where you set
the uppermost limit of the Zoom Display by pressing the UP/DOWN buttons. When
you have the desired depth highlighted, pressing ZOOM again will establish
that depth as the top of your Zoom display. You will notice that the Zoom
Indicator Bar will move up or down as you make these adjustments. To set the
size of what is shown in the Zoom Display, press MENU, and then highlight
“Zoom Window”. You can now select which size zoom window you want. Going
through this process several times before you go fishing is a great idea, as
that will allow you to easily and quickly make adjustments right away once on
the water.
If you have only the Flasher Display, the Vertical Display, or the Scrolling
Graph Display open, and go into zoom mode, pressing the “ZOOM” will cause the
vertical zoom window to appear, and a “Zoom Depth” window will open at the
bottom of the screen. You will still set the uppermost limit of your zoom
window here, but you won’t have the advantage of having the Zoom Indicator Bar
to show you exactly what area is being highlighted. With a little bit of
experience, you’ll find this to be quite easy to do. Just set the zoom depth
for 5, 10, 20, or 40 feet above the bottom, and then set the Zoom Window to
the size that is appropriate.
For example, if you were fishing in 30 feet of water, and wanted to zoom in on
the bottom 10 feet, press ZOOM, and then set the zoom depth for 20 feet (10
feet off bottom). Now press MENU, highlight “Zoom Window”, and select 10 feet.
The 20 to 30-foot portion of the water column is now displayed on the Zoom
display, and the entire water column is viewable on the flasher window.
The MarCum Digital Sonar also features “Chart Zoom” which enables you to use a
scrolling graph in Zoom mode. Activate the Chart Zoom in the Display Options
of the menu. You set the zoom just as you would when using the other sonar
options. When you press the ZOOM button to make a change, the Vertical Zoom
window will automatically open. After adjustments have been made, you may turn
the Vertical Zoom window off again in the Display Options of the menu.
CONE ANGLE INFO
A feature unique to the Digital Sonar is the “Sonar Footprint” that displays
the actual area being covered by your transducer while you are fishing. This
data is displayed below the cone angle icon, and represents the diameter of
the base of the transducer cone. This will keep you constantly updated how
much area is being covered by your Digital Sonar, and will help you decide
which transducer angle best suits the conditions. When the Digital Sonar is
first turned on, it will be transmitting utilizing the 20-degree setting. To
switch from 20 degrees to 8 degrees, simply press the CONE ANGLE button once,
and the CONE ANGLE icon will change from 20 degree to 8 degree, and the Sonar
Footprint will change with it.
Conditions where the narrow beam will benefit you are:
- Fishing in deep water (over 40’)
- Fishing along very steep drop-offs for bottom-hugging walleyes
- Fishing in big schools of fish, like suspended crappies
- Fishing in and around heavy weeds or standing timber
- When fishing in a crowd, the narrow beam will reduce interference.
INTERPRETING SIGNALS
DIGITAL DEPTH — The digital depth display on the MarCum Digital Sonar
provides a quick and easy way to determine depth. Digital Depth is always
displayed in the center of the circular display, and on the bottom of the
vertical displays. It will also show in the upper left corner of the graph in
some configurations. This display can be used as a quick reference when
checking depths through the ice.
READING BOTTOM — When interpreting your bottom signal, always read the leading
edge (shallowest side) of the signal return. If you have a strong signal
return (wide band) and it starts at 13 feet and ends at 16 feet, the correct
depth is 13 feet or the shallowest leading edge of the return signal. Anything
beyond the shallowest leading edge indicates the strength of the return
signal.
The MarCum Digital Sonar can also be used to determine bottom composition. The
thicker and bolder your bottom shows, the harder the bottom is. In some cases,
hard bottom can be indicated by a “double” or second echo that will show on
your display at approximately twice the water depth. Soft bottom (silt, mud,
muck) will only register one bottom reading.
Using your Sonar in conjunction with an underwater viewing system is a great
way to learn how to interpret your sonar signals.
READING FISH— Fish will generally appear as separate targets from the bottom.
Depending on the size of the fish and the location within the transmit beam
they can show as any of the colors in the palette you are using. RED indicates
the strongest signal on all the color palettes, and this generally indicates a
fish directly below the transducer. Smaller fish or fish on the outside of the
cone may appear orange, yellow, or even green or blue. Fish moving through the
transmit beam may change color as the return signal strengthens or weakens
reflecting their location.
Some fish, like walleyes, are notorious for cruising right on the bottom. The
Marcum Digital Sonar has target separation fine enough that it will generally
show bottom hugging fish as a separate signal. However, fish that are right on
the bottom can appear as part of the bottom. The best indication of a fish
sitting right on the bottom is that the leading edge of the bottom return
signal is a thin band of a color other than red, possibly dithering or
flickering. It is important that the sensitivity be kept to a minimum when
displaying a strong bottom return. Having your sensitivity too high will flood
out the ability to differentiate targets and clutter the display. Utilizing
the ZOOM feature can give you a magnified look at the bottom when this is
happening, and help you better learn what is going on below you. Schooling
fish, like panfish, will sometimes group in large numbers suspended off the
bottom. A big school of fish concentrated in one portion of the water column
can show on your sonar as one large “blob”, and it can be difficult to pick
out individual targets. Zooming in on the zone with the most fish will give
you better definition, and switching to the 8-degree cone will eliminate
signals from fish on the periphery of your area, improving your definition
even more.
READING LURES AND JIGS — The MarCum Digital Sonar will pick up and display
the smallest of lures and jigs. When tuning the unit to display your lure,
lower it to the desired depth and turn up the SENS until you see the lure or
bait on the display. It is important that the SENS be set so it displays the
lure or bait as you raise or lower it. Once you have the SENS set where you
want it, you can fine- tune your signals by using the TARGET ADJUST button.
NOTE: When tuning the unit to display lures or bait, make sure that the
objects are in the center of the hole and therefore in the center of the
transmit beam. If there is current (some lakes and all rivers have under water
current or movement) and the lure doesn’t weigh much, it may move to the outer
edge of the signal or out of the transmit beam altogether.
This will make it difficult or impossible to pick it up on the display. You
may find it difficult to mark your jig in shallow water, or when it is just
below the ice. See the section on shallow water fishing for more info.
The MarCum Digital Sonar has sensitivity that will enable it to display the
smallest ice jigs, as well as sinkers and swivels. The target separation of
the Digital Sonar is down to 3/4″. This means that two objects that are more
than 3/4″ apart can show as two separate signals on your display. If you have
a strike and fail to hook the fish, you can even determine if you still have
bait on your jig, or if you have to reel up and re-bait based upon how the
signal appears. Dead Zone – All sonar units will have a dead zone in certain
circumstances. This occurs on sharp drop-offs where the transmit beam (cone)
hits the shallower edge of the drop-off and returns before the deeper edge
returns. This in effect creates an undisplayed area between the shallower and
deeper water within the transmit beam. The 8-degree transducer option on the
Digital Sonar will greatly reduce this effect.
HOW TO DECIDE WHICH CONFIGURATION TO USE
With 5 different sonar windows, along with a plethora of other settings, it
can be hard to decide on which one to display. If you have used traditional
mechanical flashers in the past, you may like the familiarity of the Digital
Sonar’s flasher display. The flasher displayed with one or more of the
vertical display is likely to be how most anglers use the Digital Sonar, at
least for starters. We get endless feedback on how well the scrolling graph
display works for ice fishing, so be sure to give it a try. Be sure to
experiment with different color palettes and backgrounds, too. You can have up
to three windows displayed at once.
CIRCULAR [FLASHER] DISPLAY— This Sonar window will read much like a
traditional flasher-style display. You can set the range manually, or allow
the Auto Range or Dynamic Depth interface to automatically lock into a RANGE
that will optimize the use of the circular display. Signals are displayed as
various colored lines on the dial, and the different colors represent
different signal strengths.
VERTICAL DISPLAYS— These Sonar windows are very easy to interpret— top is the
top, bottom is the bottom. Anything in between the top and bottom is weeds,
fish, or your lure. There are two different Vertical displays—one shows the
entire water column, one shows your ZOOM window. On each one, signals are
displayed as various colored lines on the column, and the different colors
represent different signal strengths.
SCROLLING GRAPH (CHART) DISPLAYS— These windows will show not only what is
happening below you in real time, but will also enable the user to have a
“history” of what has
happened. While most commonly used for open water, many anglers are
discovering the benefits of using a graph on the ice. The Marcum Digital Sonar
stands apart from other graphs in that it displays with ultra-fast “True-Time”
sonar response – less than .02 seconds between the echo reaching the
transducer and when the signal appears on the LCD screen. Other graphs
experience a much longer response time. When used from a boat in open water,
the user will see signals displayed in classic “graph” fashion; the bottom
will be a solid band, and fish or other objects display as “arches”.
When used from a stationary position, such as ice fishing, the bottom will
display as a solid band, but other signals, like fish or your jig, will
display as lines of varying thickness. Always remember that the thicker the
band, the stronger the signal. A large fish is likely to display as a fairly
thick band, while a small ice jig will show as a very fine line. The best way
to learn how to interpret signals on the graph is to have it displayed along
with the circular or vertical display.
After using the graph along with one of the more familiar displays, you may
find that you like fishing with the graph best of all. It is fascinating to
watch the “trail” of your jigging motion, and fine tuning your presentation to
exactly what the fish want has never been easier.
The Marcum Digital Sonar has the option of displaying a full water column
graph, as well as an adjustable zoom graph. The interpretation of these
signals improves with experience and use in the field.
SOFTWARE UPDATES
Your MarCum Digital Sonar has the ability to have the software updated. We may
come out with new software versions to add features or to improve performance.
To see which version you have, press the MENU button, then select SYSTEM
SETTINGS. The version will be displayed at the top of the menu window as a
number with a “v” in front of it. To see if there are new versions available,
check our website
www.marcumtech.com/support. Compare the
software version on your system with what we have available online, and ensure
your system has the highest numbered version.
It is quite simple to do; you only need a PC, a USB 2.0 cable (sold
separately), and about 10 minutes. For more information, be sure to go to our
website, click on the support tab, then firmware updates for step-by-step
instructions and tutorial video.
OPEN WATER APPLICATION
The MarCum Digital Sonar is just at home on a boat as it is in your ice shack.
The Universal Transducer [sold separately] is designed to be mounted right to
your boat’s transom, or to the lower unit of a bow-mounted trolling motor.
This design makes it easy for you to use your Digital Sonar for high speed
scouting work, or for breaking down structure one piece at a time. You will be
able to identify the presence of fish or weeds, and be able to determine the
bottom makeup. The Universal Transducer can transmit an 8 or 20-degree cone,
and it also has a temperature sensor.
From an anchored or otherwise stationary position, you can use your Digital
Sonar from a boat much like you would on the ice—you can see the fish and how
they react to your jig on the screen. You may find that being double anchored
is necessary to maintain a stationary position.
