transmitter Controls & indiCators
The red/Black cord, Coupler and FlexicouPler connects here to create a circuit
on the buried utility.
FREQUENCY SELECTOR
This button toggles through the available frequencies. The selected frequency
is displayed on the LCD. When dual frequency transmission options are
selected, indicated by the D1 & D2 icons to the right large numeric segments,
the frequencies will flash from one to another.
SIGNAL INDICATOR (visual & audible)
The Signal Indicator symbol flashes to indicate signal output.
The quick triple beep audible tone indicates the circuit is open and no signal
is being transmitted.
A steady continuous beep indicates a closed circuit and signal is transmitted
. When the indicator blinks 4 times per second, it is indicating a nearly
short circuit. When the indicator blinks 1 time every 10 seconds, it is
indicating a nearly open circuit.
ON/OFF & OUTPUT SIGNAL LEVEL CONTROL
The ON/OFF & OUTPUT SIGNAL LEVEL CONTROL turns the unit on. With a short press
it will adjust the power output from the Transmitter. There are 3 selections
on the standard power settings. Holding down the Output Signal Level button
for 2 Seconds will turn the unit off.
WARNING!
High Power Output is a SHOCK HAZARD – Lethal voltages at the transmitter’s
output. Turn off transmitter before touching test lead or any un-insulated
conductor. Make connection to ground and target conductor before turning on
transmitter.
SIGNAL INFORMATION SELECTOR
The unit can display the relative resistance, current and voltage of the
transmitted signal. The resistance is based on the feed back from the selected
frequency and is not an actual impedance meter. The selections can be toggled
by pressing the SIGNAL NFORMATION button.
Direct Connection
CAUTION DO NOT CONNECT TO LIVE OR ENERGIZED POWER CABLES
Direct Connection is the most reliable method of signal application. This
method is relatively free of interference. The greatest amount of signal
strength can be achieved by this method. Low, mid, and high frequency may be
used. The far end of the utility must be grounded.
Connect the red TesT cord to an existing ground point or an exposed metallic
section of the utility. Place the Ground rod approximately 10 feet from this
point, at an angle of 90º to the buried cable or pipe. Push the Ground rod
into the ground 8 to 10 inches. Connect the Black TesT cord to the Ground rod.
Plug the red/Black TesT cord into the TX OUTPUT JACK. Select the desired
frequency. The Signal Output Indicator will flash once signal is
established.
Coupler & FlexiCoupler Connection
The optional FlexicouPler and Hard couPler are very easy to use, and services
do not have to be interrupted. The operation range is shorter than for Direct
Connection methods. The tracing signal can be affected by neighboring cables
and pipes. The red/Black TesT cord or the Ground rod are not needed for this
method.
Successful couPler operation requires an insulated conductor that is grounded
on both near and far ends.
Loop the FlexicouPler around the cable and connect the two ends, or clamp the
Hard couPler around the cable. It is important to connect the couPler around
the cable needing to be traced. Connect the couPler around the wire closer to
the outgoing cable not near the system ground.
The result will be a stronger signal. By connecting near the grounding, the
range will also be shorter, and difficulty may arise determining one cable
from another.
Plug the couPler into the TX OUTPUT JACK.
Some couplers are frequency specific, others can operate on medium and high
frequencies.
INDUCTIVE CONNECTION
This method is convenient to use, and services are not interrupted. No test
cords or connections are needed. The cable or pipe must have good insulation
or non-conductive coating, or the operating range will be short.
Turn the TransmiTTer ON. This method of signal application only works on
frequencies from 33kHz through 478 kHz. Place transmItter on Its sIDe as close
as possible to the path of the cable or pipe.
Align the ARROWS on the SIDE OF THE TRANSMITTER in line with the cable or
pipe. First, locate the broad TransmiTTer Null, then move toward the expected
cable path while looking for the signal carried by the cable.
Start tracing the path with the receiver 25 feet from the TransmiTTer. Search
in the 90º zone as shown above. Locate the cable or pipe, and follow the path.
If the signal becomes weak, move the TransmiTTer to a point 25 feet behind the
last strong signal, and continue searching.
BLIND SEARCH
The Blind Search locating techniques is used if the operator is not aware if a
buried utility exists.
Two people are needed for this technique. The Transmitter and the receiver are
Held 25 feet away from each other. Each operator walks at the same speed
keeping a distance of 25 feet from each other. When the receiver gives an
audio response, then a buried utility is present between the receiver and the
Transmitter.
SELECTING THE TRACING SIGNAL
The choice of frequency is dependent on the conditions of the locate. It is
generally accepted that lower frequencies provide a more accurate locate.
Therefore it is generally advised to use the lowest frequency that effectively
conducts on the target line. Lower frequencies are less likely to bleed onto
adjacent non-target lines, but low frequencies are less effective at locating
higher-resistant conductors.
FREQUENCY RANGES
Frequencies are classified into three major categories, Low, Medium and High
and they are classified as follows:
• Low Frequencies | < 1 kHz (1000 Hz) | e.g. 512 Hz, 640 Hz, 815 Hz |
---|---|---|
• Medium Frequencies | 1 kHz to 44 kHz | e.g. 4 kHz, 8 kHz, 33 kHz |
• High Frequencies | 44 kHz to 480 kHz | e.g. 65 kHz, 82 kHz, 200 kHz |
FREQUENCY CHARACTERISTICS
The low, medium and high frequencies each have their advantages. It is
recommended to begin by using a low frequency, and continue as long as you are
confident in the results. If the signal is very weak try to adjust the
connection or grounding. If there is no improvement in signal then try mid-
range frequencies. Again, if there is weak or absent signal, repeat
adjustments of the grounding and connection point before switching to a high
frequency.
The method of signal application may dictate the frequencies used. While
direct connection can be performed on any frequencies, coupler induction will
only work with medium and high frequencies and transmitter induction will only
work on the highest of the medium frequencies (33kHz) and high frequencies.
Low Frequencies are usually preferred to the mid-range frequencies and
high frequencies because they are less susceptible to locating errors caused
by coupling of signal to adjacent conductors, cables or pipes. The low
frequency locating range is also much longer than the medium and high
frequencies. Low frequencies will not travel well on highly resistive lines or
conductors that have interruptions in their continuity (e.g. disconnected
shield bonds or insulated pipe bushing). Low frequencies may only be applied
via direct connection.
Medium Frequencies take the best of both high and low frequencies. Medium
frequencies are not as susceptible to bleed off or coupling as the high
frequencies, and medium frequencies can jump minor breaks in continuity and
conduct on higher resistant lines better than low frequencies. It is still
best to use low frequencies whenever effective, but 8 kHz and 33kHz are of the
most common frequencies used in locating. Medium frequencies may be applied
via direct connection and via coupler induction [Note: 33kHz may be applied
via transmitter induction].
High frequencies are sometimes better than the low frequencies for
locating highly resistant lines as well as conductors that have breaks in
their continuity (e.g. disconnected shield bonds or insulated pipe bushing).
The locating range is quite short for the high frequencies so the TransmiTTer
must be repositioned more often during the tracing operation. High frequencies
may be applied via direct connection, coupler induction and transmitter
induction.
SNAPTRACK RECEIVER CONTROLS & INDICATORS

GAIN Button (Up or Down)
Adjusts the gain up or down. If the graph shows signal strength off scale,
pressing the GAIN will automatically adjust to 50% on the scale display.
Pathlink Controls
The optional Pathlink feature enables the user to remotely control the
transmitter with the receiver. The frequency and power output of the
transmitted signal can be controlled up to 800 meters (874 yards).
If your unit does not have the PathLink module, the program will not allow the
menu to select the option on.
Turning On and Off Pathlink
- To turn on the remote control feature, PaTHlink, start with the unit on.
- Press and hold depressed the Power On button for 10 seconds.
- “Pro” will display at the top of the LCD.
- Using the frequency key scroll through the primary menu to “P-Link”.
- Use the GaIn uP key to select the P-Link Menu.
- Use the frequency key to select the to select P-Link “on” or “off”.
- Exit the P-Link Menu submenu by pressing GaIn Down.
- To exit the Programming menu and return to locating, short press the On/Off – Function key.
- In a moment the PathLink Indicator will be displayed on the receiver LCD indicating the unit has linked with the transmitter.
Changing the transmitted frequency with PathLink
Select the desired active frequency by pressing the Frequency key. Once the desired frequency is selected, the icon of the transmitter will flash momentarily then becoming solid confirming the selected frequency has been set at the transmitter. If the transmission is incomplete or if the frequency requested is not available, then the symbol will continue to flash and ‘ ‘ with display momentarily display on the receiver’s LCD.
Locating modes
There is a variety of locating modes available in the SnapTRACK unit. PEAK, PINPOINT PEAK, NULL LEFT/RIGHT GUIDANCE, SONDE, DFF & ACC. To toggle through PEAK, PINPOINT PEAK & NULL simple press the mode button. To toggle to SONDE mode hold the MODE button for 5 seconds and release. DFF and ACC modes are only selectable when an appropriate accessory is plugged into the accessory port in the handle of the receiver.
Peal mode Locating
Peak and Pin Point Peak modes have less error rates than the null locating
mode in most circumstances. The peak mode location indication should be
verified by the null to ensure locating accuracy.
With the receiver in a vertical position. Move the receiver left to right
across the path. When the receiver is directly above the cable or pipe, rotate
the receiver for a maximum signal. As you move the receiver away from the
cable path, the meter reading (and audio frequency response) will drop off.
The Left/Right arrows operate off of the Null reading. By utilizing the
Left/Right arrows while in Peak mode the user can simultaneously locate in
both modes thus quickly identifying the match or discrepancy between the Peak
and the Null reading. If you rotate the receiver while over the cable, a sharp
NULL will identify the cable’s direction. It is aligned with the flat side of
the receiver.![JAMESON 17 300RTK Tracer Cable Pipe Receiver w Transmitter Kit

content/uploads/2023/09/JAMESON-17-300RTK-Tracer-Cable-Pipe-Receiver-w
-Transmitter-Kit-CABLE-AND-PIPE-SIGNAL-LOCATING-DIRECTION.jpg)Trace the path
by walking away from the TransmiTTer at a moderate pace. Move the receiver to
the left and right while walking, following the PEAK indications.
As you trace the path, the PEAK meter reading may slowly fade as you move away from the TransmiTTer. Press and release the GAIN buttons as needed to compensate for changes in level (higher or lower). One of the following may occur:
a) a junction where the signal divides and goes several directions.
b) a break in the cable or shield.
c) a change in the depth of the cable or pipe.
d) an insulated pipe fitting.
e) a slack loop of cable.
If you can no longer trace the path, even with the GAIN set to maximum,
connect the TransmiTTer to the far end of the path and trace back to the point
where you lost the signal.
Mark the straight sections of the path every few feet. Mark sharp curves,
loops, and cable bundles every few inches. Sharp changes in the path cause the
receiver PEAK and NULL indications to behave differently than when tracing a
straight path. Practice on the path that you know has turns and laterals in
it. This will help you to recognize the conditions within the field.
Null Mode Locating
Move the receiver left to right across the cable path. When the receiver is
directly above the cable or pipe, a NULL (lowest meter reading and lowest
audio tone) will occur. When moving the receiver to left or right of the NULL
point, the meter reading will rise to a maximum point (PEAK). The audio tone
will also be at its highest pitch. When the receiver is moved beyond the PEAK,
the meter reading will begin to fade.
Trace the path by walking away from the TransmiTTer at a moderate pace. Move
the receiver to the left and right when walking, following the NULL
indications.
It is expected that in areas of distortion and interference the Null locating
mode will have a greater error rate than the Peak locating mode.
Left Right Auto Gain Directional Locating
In this mode the unit
will display directional arrows to the conductor. The audio indicator will
provide a solid tone on one side of the conductor and a pulsed tone on the
opposite side of the conductor. When the unit is centered in the
electromagnetic field the tone will null and the depth will briefly display at
the top of the LCD. This mode is gain independent.
The Left/Right arrows operate off of the Null reading and will have the same
error rate as the Null locating mode. By utilizing the Left/Right arrows with
the absolute signal strength reading the user can simultaneously locate with
both Peak and Null modes, thus quickly identifying the match or discrepancy
between the Peak and the Null reading.
Absolute Signal Strength
The SnapTRACK receiver provides the operator with a direct measurement of the
receiver’s signal strength. The measurement is displayed with three numerical
digits (ex: 485) located at the top of the LCD display. The measurement range
is from 0 to 999 indicating a very week signal (0) to a very strong signal
(999). Absolute Signal Strength is independent of the GAIN setting or meter
reading. It gives the operator information about the actual amount of signal
being radiated from the conductor and received by the receiver.
Measuring Absolute Signal Strength at any time is done by reading the number
at the top of the LCD display. The Absolute Signal Strength will not be
displayed if the meter reading is too high or too low. Adjust the GAIN to move
the meter reading to mid-scale. The numerical display will change from ‘—’ to
a valid measurement.
Absolute Signal Strength measurements are more sensitive to signal changes
than the meter display. PEAKS and NULLS can be more precisely pin-pointed.
This measurement can also be used to monitor signal loss as the conductor is
being traced.
Gain Level Indication
The GAIN up and down buttons are used to increase and decrease the gain in small amounts. If the meter reading is very low, pressing the GAIN up button will center the meter reading to mid-scale. Likewise, if the meter reading is very high, pressing the GAIN down button will center the meter reading to mid- scale.
Passive 50/60 Hz Locating
The SnapTRACK receiver is capable of locating power utility frequencies. This
MODE is useful for locating underground primary and secondary power utilities.
In certain circumstances, this MODE will also locate water pipes, sewer lines,
cable television, and telephone. The reason is that common electrical grounds
are sometimes found among these various utilities. Select 50Hz or 60Hz
frequency on the receiver. PINPOINT PEAK mode will automatically be selected
as the preferred method to locate the conductor in passive power mode.
This method is useful because of its speed and convenience. Start at a known
reference point and keep in mind that other conductors in the area may produce
this same locating signal.
The Transmitter is not required to locate in this mode.
Note: The unit of depth measurement determines the selection of either
50Hz or 60Hz passive mode. The unit is configured for 50Hz when in Metric
Measurement mode and 60Hz when in English Measurement Mode. To change unit of
measurement press and hold the frequency button for 10 seconds, when released
the unit will toggle measurement units.
Passive Radio Frequency Locating
The SnapTRACK receiver is capable of passively locating metallic utilities
where radio frequencies have coupled to the utility. This mode is useful for
sweeping a green area for utilities. In certain circumstances, this mode will
locate water pipes, cable television, gas lines and telephone. This locating
option does not always detect buried utilities even when radio frequencies are
present. This method is useful because of its speed and convenience. Start at
a known reference point and keep in mind that other conductors in the area may
produce this same locating signal.
The Transmitter is not required to locate in this mode.
Passive Rectifier CP Locating
The SnapTRACK RECEIVER is capable of locating the rectified signal of
Cathodically Protected utilities at 120Hz and 100Hz. This method is useful
because of its speed and convenience. Start at a known reference point and
keep in mind that other conductors in the area may produce this same locating
signal.
Note: The unit of depth measurement determines the selection of either
100Hz or 120Hz passive mode.
The unit is configured for 100Hz when in Metric Measurement mode (for 50Hz
power) and 120Hz (for 60Hz power) when in English Measurement Mode. To change
unit of measurement press and hold the frequency button for 10 seconds, when
released the unit will toggle measurement units.
The TRANSMITTER is not required to locate in this mode.
Push Button Depth
The only way to be sure of the depth of a utility is to exposes the utility.
At any given time, the depth readout may be inaccurate.
The SnapTRACK Receiver can perform digital depth measurement. The depth is
displayed at the top of the LCD display in centimeters or feet and inches.
Push button depth is useful in quickly estimating the depth of the conductor
during path locating.
Begin this measurement by locating the path of the cable or pipe. Stay at
least 15 feet (4.6 meters) away from the Transmitter. Pin-point this location
as accurately as possible. Place the Receiver vertically over the conductor
and rest the foot of the locator on the ground. While holding the Receiver
vertical, press and release the DEPTH button. The Receiver will briefly
indicate a measurement is being performed and then display the depth at the
top of the LCD display.
Caution must be exercised when using the push button depth feature, as tilted
magnetic fields and adjacent conductors can significantly influence this
measurement. The operator should periodically check for adjacent conductors
and tilted magnetic fields when taking push button depth readings. For
information on identifying tilted magnetic fields, refer to Tilted Magnetic
Field Identification and Depth Measurement 45º Method.
Depth is determined by reading the electromagnetic field radiating from the
conductor. The field must be even and circular for the most accurate reading.
Interference of this field may be caused by bends in the cable, faults on the
target conductor and signals radiating from adjacent non-target conductors.
Interference will warp the field and skew the depth reading. The only way to
be sure of the depth of a utility is to expose the utility. At any given time,
the depth readout may be inaccurate.
The following are methods and procedures that will aid in increasing the reliability and testing the accuracy of the depth reading:
- Take depth readings at least 5 yards from cable bends or depth changes. Follow the cable both forward 5 yards and backward 5 yards, ensuring the line is straight and there is a consistent signal strength reading.
- Check for non-target conductors within 5 yards of the target cable. Sweep the area looking for coupled signals into both the tracks and adjacent cables. Adjacent conductors carrying the locate signal can result in a 50% error rate of the depth reading.
- Test for interference in the magnetic field by comparing the PEAK location to the Null location. The determined cable position by these methods should be within 3 inches of each other. A greater disparity will indicate interference resulting in inaccurate depth.
- Place the receiver vertically over the conductor and perpendicular to the conductor. Rest the foot of the locator on the ground. Take several depth readings moving slightly across the perpendicular plane to the conductor looking for the lowest depth reading.
- Once the lowest depth reading is found, take several readings. Each reading should be within one inch of the other reading. Wider variation will indicate interference resulting in inaccurate depth.
- Lift the receiver up 12 inches and take a depth reading. The reading should reflect the change in distance accordingly. If not, interference is present resulting in inaccurate depth.
- Verify the depth reading using the triangulation method as described below:– Mark the path on the ground as precisely as possible using the Null method.
– Place the Receiver on the ground with the LCD meter facing up. Position the unit so that the Bubble Level on top of the meter is centered (45º).
– Pull the Receiver away from the cable path (at 90º to the cable path) keeping the Bubble Level centered.
– When the receiver indicates a Null reading, mark the location of the receiver’s foot.
– The distance between the Receiver and the cable path is the depth of the pipe or cable. A false depth reading may be caused by nearby buried metallic objects, such as a second cable, pipe, sewer, fence or railroad track.
– Confirm the depth measurement by repeating the above steps on the opposite side of the pipe or cable.
– A variance greater than 5 inches in depth measurement may indicate interference from adjacent cables, pipes or other objects.
Depth Measurement 45º Angle Method
Move to the location you want to measure depth. Stay at least 15 feet away
from the Transmitter. Move the receiver left to right across the path until
the cable is located. Mark the path on the ground as precisely as possible
using the Null Method.
Place the receiver on the ground with the LCD meter facing up. Position the
unit so that the BUBBLE LEVEL on top of the meter is centered (45º). Pull the
receiver away from the cable path (at 90º to the cable path) keeping the
BUBBLE LEVEL centered. When the receiver indicates a NULL reading, mark the
location of the receiver’s foot. The distance between the receiver and the
cable path is the depth of the pipe or cable.
A false depth reading may be caused by nearby buried metallic objects, such as
a second cable, pipe, sewer, fence or railroad track. Confirm the depth
measurement by repeating the above steps on the opposite side of the pipe or
cable.
A variance greater than 5 inches in depth measurement may indicate the
presence of additional buried cables, pipes or other objects.
Current Measurement
The SnapTRACK receiver contains a feature that is very useful in identifying a
desired cable in a field of various conductors and/or utilities. It is not
unusual for the target conductor (the conductor connected to the transmitter)
to induce a signal into nearby conductors in a crowded field. In these
instances, the radiated signal on the conductors close to the surface of the
earth, may be stronger than the Transmitter signal on the target conductor
buried deep in the ground. The operator will find two or more paths and must
determine which is the target conductor. By using the current measurement
feature of the SnapTRACK receiver, the operator can determine the amount of
815 Hz, 8 kHz, 33kHz or 82 kHz current flowing on the conductors, regardless
of the depth. The highest current flow indicates the target conductor.
Place the receiver vertically over one of the conductor marks and rest the
foot of the locator on the ground. Holding the receiver vertical, press and
release the Shift Button & Depth button simultaneously. When the meter changes
from a “thermometer” type display to a “bar” type display, hold the receiver
still until the measurement stabilizes. The blinking bar indicates the signal
level on the cable (adjusted for depth). Next, move to the second cable and
repeat the measurement. The blinking bar will show the signal level on the
conductor. In addition, the previous reading is shown as a solid bar. The
higher of these two readings will show which conductor is carrying the
greatest locating signal.
Tilted Magnetic Field Identification
When adjacent cables or pipes are present, they will sometimes create locating
errors. Some of the Transmitter signal is picked up by the adjacent conductors
and is redirected so that it combines with the original signal. The result is
a Tilted Magnetic Field. This is often the reason that numeric depth readouts
are sometimes created in error.
The operator can verify the accuracy of path locate by performing a variety of
tests.
- The 45º Angle Method locate on both sides of the cable path. If the right and left side depth readings agree to within 5 inches, the path locate is accurate. If the two depth readings do not agree, then dig with care. A closer locate would be halfway between the two outside depth locate marks.
- Test for interference in the magnetic field by comparing the PEAK location to the Null location. The determined cable position by these methods should be within 3 inches of each other. A greater disparity will indicate interference resulting in inaccurate depth.
NOTE: The Left/Right arrows operate off of the Null reading. By utilizing the Left/Right arrows while in peak mode the user can simultaneously locate in both modes thus quickly identifying the match or discrepancy between the Peak and the Null reading.
These are important techniques that should be used to ensure the most accurate location possible.
Locating a Sonde or Camera head
Before you begin, you must choose a sonde or camera Head that will match the
same frequency as the receiver. You will need a sonde with a frequency of
512Hz, 640Hz, 815Hz or 33kHz to use with the SnapTRACK Locator Receiver.
To select SONDE locating mode press and hold the MODE key for 5 seconds. When
released the SONDE ICON will be displayed on the LCD. Once in SONDE mode the
FREQUENCY button will select the available SONDE frequencies.
The key to sonde locating success is practice and patience. Before going out
on your first locate, it is a good idea to take your receiver and sonde out
and try locating the sonde and calculating the depth.![JAMESON 17 300RTK

Attaching a push device to the sonde
Attaching a push rod to the sonde can be accomplished by using the coupling on the end of the sonde. A spring coupling is recommended to allow the sonde to move easier. Or, if you need to attach the sonde to a sewer auger, it is recommended you use duct tape and apply as the shown in the figure below. If taping the sonde on a metal pushing device, it is recommended to place the battery side of the sonde closest to the device. This will allow for the best performance. Wrap the snake for approximately 1 foot in the location where the sonde is going to be attached. Also attaching the sonde 18 inches behind the cutting head is recommended. First, wrap the sonde in the duct tape and then attach the sonde to the snake using the duct tape.![JAMESON 17 300RTK Tracer Cable Pipe Receiver w Transmitter Kit - CABLE AND PIPE SIGNAL LOCATING

Locating a sonde
Hold the receiver antenna directly above and in line with the sonde, as shown
below. The receiver sensitivity needs to be adjusted for a meter reading
indication between 60% to 80%.
The radiation pattern of the sonde is shown below. The PEAK signal is when the
receiver is held directly over the sonde with the antenna in line with the
sonde. Both Ghost signals can be located behind and in front of the sonde. By
locating the ghost signals, the user is confirming the accuracy of the
locate.Start by following
the suspected path of the pipe. Stop locating when the PEAK reading is found.
Then rotate the receiver as shown in the figure below. When pivoting the
receiver, do not change the vertical position. The receiver will indicate a
PEAK when the receiver antenna is in line with the sonde.![JAMESON 17 300RTK

When the PEAK if found, the receiver is directly over the sonde. Mark this location. Next, check for ghost signals in front of and in back of the sonde to confirm the location.
MOVE THE RECEIVER SIDE TO SIDE AND WHEN A PEAK SIGNAL IS FOUND, THE RECEIVER IS OVER THE SONDE
Depth measurement of Camera head or sonde
Once the line has been located, the depth can then be found. Refer to the figure below for a reference. Start by moving the receiver along the path behind the sonde with the antenna in line with the sonde and find a NULL between the PEAK ghost signals. Mark this point (A). Then move the receiver along the path in front of the sonde and find another NULL. Mark this point (B). Next, measure the distance between these two points. The depth of the pipe is 0.7 times the distance between the two points.

Introduction
Congratulations on the purchase of your new Jameson Locator. The Locator is
specially designed to detect conductors such as buried pipes & cables. This
device may detect buried power cables, CATV cables, gas and water pipes, sewer
lines, telecommunication lines, fiber optic cables with sheath, sondes,
inspection camera transmitters. You have chosen a quality product that is
designed for years of field use without the need for annual or periodic
calibration and service.
The basic principle of the locator’s operation is as follows:
The TransmiTTer emits a signal to a conductive cable or pipe. The receiver
detects the electromagnetic field that is generated by the transmitted signal.
You can locate the relative position of the buried utility by following the
tracing signal.
For safely & to help ensure the best locating results, please read &
understand the manual in its entirety before using the product.
