•Exposing the utility is the only way to verify its
existence, location and depth. Ridge Tool Co., its
aliates and suppliers, will not be liable for any injury
or any direct, indirect, incidental or consequential
damages sustained or incurred by reason of the use
of the NaviTrack.
NOTE: Connection To Energized Conductors
The line transmitter is designed to withstand up to
240 VAC 50/60 Hz excitation between the two leads. The user
is cautioned not to deliberately connect to live power lines.
The protection is not intended to be used continuously. If the
transmitter indicates the presence of high voltage, use high
voltage precautions to carefully disconnect the line transmitter
from the high voltage source.
•The line transmitter is normally powered by internal
batteries,andisdesignedtoprotecttheuserfromvoltages
up to 240 VAC that may be accidentally encountered.
Powering the line transmitter by batteries provides the
highest level of isolation and safety, and is therefore the
recommended power source.
•The line transmitter may also be powered by an optional
external power supply. The user must ensure that the
external power source is fully isolated from ground
and from the power mains. The user is cautioned to
use only external power sources recommended by the
manufacturer. If a line transmitter is powered by an
external source that is not isolated from ground and from
the power mains, the line transmitter is not protected
from connection to live power lines! The line transmitter
may be destroyed and may present a safety hazard.
DO NOT USE NON-ISOLATED POWER SUPPLIES WITH
THE LINE TRANSMITTER.
•Wear appropriate heavy soled footwear as you would
when working with any high-voltage equipment.

NOTE: When replacing batteries use 8 D cells that are the
same type. Do not mix half-used alkalines with brand new
ones.
CAUTION: Always remove batteries before shipping the
unit.
CAUTION: Do not allow debris or moisture into battery
compartment. Debris or moisture may short the battery
contacts, leading to rapid discharge of the batteries, which
could result in electrolyte leakage or risk of re.
Operation Time
Typical operation time for the SeekTech line transmitter, using
alkaline cells, is about 12.5 hours which varies depending on
factors such as load and current transmitted, and how much
thebacklightison.Select theBatterySaverfeatureifextended

Using the ST-510 Line Transmitter
The ST-510 line transmitter can apply an active tracing signal
to a target conductor in three ways:
Figure 5
Figure 6
Figure 7

Ridge Tool Company 7
Tools For The ProfessionalTM
SeekTech®ST-510
Direct Connect – The receiver’s leads are connected directly
to the target conductor or tracing wire, and a suitable
ground.
Inductive Clamp (optional) – The jaws of the inductive
clamp encircle the target conductor; there is no metal-to-
metal contact.
Inductive (internal coils) – The transmitter is placed over
and in-line with the utility. Its internal coils generate a eld
which induces current in the underground target conductor.
DANGER! Always connect leads before turning
the transmitter on to avoid electrical shock. Ensure
transmitter is well grounded.
Direct Connect Method
1. Attach the ST-510 line transmitter to
the ground and to the target line.
Insert the ground spike into the ground. Connect one of the
cable leads to the grounding spike.
Figure 8: Attaching Lead to Ground Stake
2. Connect the other lead to the target
conductor.
Figure 9: Example of Connecting to a Gas Line
Figure 10: Alternative Connection to a Pipeline

Tools For The ProfessionalTM
SeekTech®ST-510
DANGER! NEVER CONNECT TO LINES ENERGIZED
WITHAPOTENTIALLYDANGEROUSELECTRICALCURRENT.
To increase safety, the ground lead should be attached rst.
If there were an unknown high voltage running through
the target line, this would allow a means of redirecting the
current away from the transmitter and operator.
ALWAYS HOOK UP LEADS FIRST BEFORE POWERING THE
UNIT ON TO AVOID SHOCK.
ALWAYS TURN UNIT OFF BEFORE DISCONNECTING
LEADS.
3. Select a Frequency
The ST-510 line transmitter provides ve frequencies:
Figure 11: Frequency Selection
NOTE: For 93 kHz, press the 33 kHz button a second time.
4. Check the Circuit
More current gives a stronger signal. Less current prolongs
battery life.
To prolong battery life and reduce the chance of the signal
“bleedingover”ontoadjacentlines,usetheminimumamount
of current needed to get a clear reading on the receiver.
Look at the ohms (Ω) (resistance), the voltage (V) and the
current (mA) displayed on the screen. Generally the lower
the ohms (total resistance) the more eciently current can
be added. Lower total resistance indicates an ecient circuit
and requires less voltage to illuminate the line.
Figure 12: Display Panel
NOTE: Ohms, current, power and voltage displayed are
approximate values.
The transmitter will beep faster if the resistance is lower, and
slower if the resistance is higher.

5. Adjust Current
Use the up and down arrows to adjust the amount of current
in milliamps (mA).
There are 7 current levels that the user can choose from:
5, 25, 50, 100, 200, or 400 mA.
Figure 13: Current Selected
When a current level is chosen, the transmitter will adjust the
voltage to try and produce the selected current and lock it
in. If the transmitter cannot produce the current selected it will
adjust down to the next level.
The transmitter’s maximum current output depends on the
amount of resistance in the circuit. When the transmitter is
putting out the maximum current possible for internal and
external conditions, MAX will be displayed in place of the
current strength number.
Figure 14: MAX Current
MAX will also appear if the power output of the transmitter is
at its allowable limit. (See FCC limits in the Useful Information
section on page 14.)
When the current drops below 5 mA,“LO”will appear instead
of a number.
Figure 15: LO Current
WARNING: If the transmitter is showing low or no current,
the signal may be too low to be detected by the receiver
locator and inadequate for tracing.
6. Check the Receiver
Set the receiver’s frequency to match that on the transmitter.
Conrm the receiver is picking up the transmitted frequency
by holding it near the transmitter and observing the increase
in receiver signal.
Useful Operating Points
• To help lower the resistance of the circuit, scrape away
dirt, paint and corrosion before connecting to the target
conductor or grounding spike.
• Moist ground is a better conductor than dry soil. Wetting
the ground can improve a circuit in dry soil.
• The transmitter’s leads can act as antennas, broadcasting
a strong signal. If locating close to the transmitter, keep
the leads as short as possible by stowing the excess
length in the transmitter’s side pockets. This will reduce
the amount of interfering signals from the leads.
• It is usually best to start by using the lowest frequency
and the least amount of current needed to eectively
illuminate the line. Lower frequencies travel farther.
Higher frequencies generally make it easier to illuminate
a line, but they do not travel as far and are much more
likely to couple onto other utility lines. This can distort
the signal and reduce accuracy.
DANGER! ALWAYS HOOK UP LEADS FIRST BEFORE
POWERING THE UNIT ON TO AVOID SHOCK. ALWAYS
POWER UNIT OFF BEFORE DISCONNECTING LEADS.

Inductive Clamp Method
Figure 16: Inductive Clamp (Optional)
1. Plug the inductive clamp into the 1/4” phone jack
above the battery cover. Plug must be mono or, if
stereo, connected between tip and base. The coil
cords are disabled when the clamp is connected.
2. Clamp the jaws of the Inductive Clamp around a
section of the pipe or cable to be traced.
3. Power the transmitter on and proceed as in the
Direct Connect method. Be sure the receiver and the
transmitter are set to the same frequency.
Inductive Mode
The ST-510 can be used without a direct connection to a
pipe or cable. In Inductive Mode, the ST-510 generates a
eld which induces a current into a conductor such as a pipe
running directly beneath it.
1. Be sure that the transmitter is positioned correctly
over the line.
Figure 17: Orientation to the Conductor
(Inductive Mode)
2. Push the inductive mode (upper right) button to
induce a signal onto the line. The Inductive Mode
message will appear on the screen.
Orientation Mark

Ridge Tool Company 11
Tools For The ProfessionalTM
SeekTech®ST-510
Figure 18: Inductive Mode Key
3. Lower frequencies couple poorly inductively. When
using Inductive Mode, use higher frequencies in order
to get a good signal at the receiver.
4. Note that the line into which current is induced must
be grounded in both directions for a signal to be
induced away from the transmitter.
5. The transmitter in inductive mode will generate a eld
through the air around it as well as into the ground
under it. If the receiver is within about 20-30 feet of
the transmitter it will measure this eld instead of on
the target conductor. Place the transmitter at least
20 feet away from the region where tracing occurs in
order to avoid this“air coupling”.
Figure 19: Air Coupling
6. Generally if you trace a line with an induced signal
checking for a valid depth measurement and a strong
stable proximity signal is the best way to conrm that
you are locating the induced signal in a line and not
the signal directly from the transmitter through the
air (air coupling).
NOTE: If you have been using the ST-510 in inductive mode,
be certain to switch inductive mode o if you are going to
use the unit in direct connect mode. Air coupling can create
very confusing signals if you inadvertently have the unit set
to inductive mode but are trying to use it in direct connect
mode.

Useful Information
Using High and Low Frequencies
High Frequencies:
• Don’t travel as far
• Overcome some barriers
• Bleed-over more.
Low Frequencies:
• Travel further
• Lose signal when hitting barriers, gaskets, poor
insulation
• Do not bleed-over as much.
As a general rule, detecting with lower frequencies is more
reliable for the reasons given above, IF you can get a good
signal.
FCC Limits
47 CFR 15.213 says that from 9 kHz up to (but not including)
45 kHz, peak output power shall not exceed 10 W. From
45 kHz to 490 kHz, it must not exceed 1 W.

Before transporting make sure that the unit is OFF to preserve
battery power.
Make sure that the ST-510 line transmitter is secure and does
not bounce around or get bumped by loose equipment.
The ST-510 line transmitter should be stored in a cool dry
place.
NOTE: If storing the ST-510 line transmitter for an extended
period of time, the batteries should be removed. If storage
is brief then the battery carriage may be pulled out ½ an
inch to preserve battery power. Remove batteries entirely
before shipping.
Maintenance and Cleaning
1. Keep the ST-510 line transmitter clean with a damp
cloth and some mild detergent. Do not immerse in
water.
2. When cleaning, do not use scraping tools or abrasives

HINWEIS: Verbindung mit Energie führenden Leitern
Der Leitungstransmitter ist so ausgelegt, dass er einer
Erregung mit bis zu 240 V Wechselstrom 50/60 Hz zwischen
den beiden Klemmen standhält. Der Benutzer sollte das
Gerät aber nicht absichtlich an Strom führende Leitungen
anschließen. Der Schutz ist nicht für einen Dauereinsatz
ausgelegt. Wenn der Transmitter das Vorhandensein
von Hochspannung anzeigt, treen Sie entsprechende
Vorkehrungen, um den Leitungstransmitter vorsichtig von der
Hochspannungsquelle zu trennen.
•Der Leitungstransmitter wird normalerweise
von internen Batterien gespeist und schützt den
Benutzer vor Spannungen bis 240 V Wechselstrom,
die unbeabsichtigt angelegt werden. Das Betreiben
des Leitungstransmitters mit Batterien bietet ein
Höchstmaß an Isolierung und Sicherheit, Batterien
werden daher als Stromquelle empfohlen.
•Der Leitungstransmitter kann auch über ein optionales
externes Netzteil versorgt werden. Der Benutzer muss
sicherstellen, dass die externe Stromquelle vollständig
vom Erdanschluss und vom Stromnetz isoliert ist. Es
dürfen ausschließlich vom Hersteller empfohlene
externe Stromquellen verwendet werden. Wenn ein
Leitungstransmitter von einer externen Stromquelle
gespeist wird, die nicht gegenüber dem Erdanschluss
und dem Stromnetz isoliert ist, ist der Leitungstransmitter
nicht vor derVerbindung mit Strom führenden Leitungen
