• Do not expose equipment to rain or wet
conditions. Water entering equipment will
increase the risk of electrical shock.
• Do not abuse the cord. Never use the
cord for carrying, pulling, or unplugging
the power tool. Keep cord away from heat,
oil, sharp edges, and moving parts. Dam-
aged or entangled cords increase the risk
of electric shock.
• If operating equipment in a damp loca-
tion is unavoidable, use a ground fault
circuit interrupter (GFCI) protected
supply. Use of a GFCI reduces the risk of
electric shock.
• Keep all electrical connections dry and
off the ground. Do not touch equipment
or plugs with wet hands to reduce the risk
of electrical shock.
Personal Safety
• Stay alert, watch what you are doing,
and use common sense when operat-
ing equipment. Do not use equipment
while you are tired or under the influence
of drugs, alcohol, or medication.A moment
of inattention while operating equipment
may result in serious personal injury.
• Use personal protective equipment.
The appropriate use of protective equip-
ment such as safety glasses, a dust mask,
non-skid safety shoes, a hard hat, high vis-
ibility clothing, and hearing protection will
reduce personal injuries.
• Do not overreach. Keep proper footing
and balance at all times.This enables bet-
ter control of the equipment in unexpected
situations.
• Dress properly. Do not wear loose cloth-
ing or jewelry. Keep your hair, clothing, and
gloves away from moving parts. Loose
clothes, jewelry, and long hair can be
caught in moving parts.
General Safety Rules
WARNING
Read all safety warnings and instruc-
tions. Failure to follow the warnings and
instructions may result in electric shock,
fire, and/or serious injury.
SAVE THESE INSTRUCTIONS!
Work Area Safety
• Keep your work area clean and well lit.
Cluttered or dark areas invite accidents.
• Do not operate equipment in explosive
atmospheres, such as in the presence
of flammable liquids, gases, or dust.
Equipment can create sparks which may
ignite the dust or fumes.
• Keep children and bystanders away
while operating equipment. Distractions
can cause you to lose control.
• Avoid traffic. Pay close attention to mov-
ing vehicles when using on or near road-
ways. Wear visible clothing or reflector
vests.
Electrical Safety
• Avoid body contact with earthed or
grounded surfaces such as pipes, radi-
ators, ranges, and refrigerators. There is
an increased risk of electrical shock if your
body is earthed or grounded.
• An improperly grounded electrical out-
let can cause electrical shock and/or
severely damage equipment. Always
check work area for a properly ground-
ed electrical outlet. Presence of a three-
prong or GFCI outlet does not ensure that
the outlet is properly grounded. If in doubt,
have the outlet inspected by a licensed
electrician.

Equipment Use and Care
• Do not force equipment. Use the correct
equipment for your application.The correct
equipment will do the job better and safer
at the rate for which it is designed.
• Do not use equipment if the power
switch does not turn it on and off. Any
equipment that cannot be controlled with
the power switch is dangerous and must
be repaired.
• Disconnect the plug from the power
source and/or the battery pack from the
equipment before making adjustments,
changing accessories, or storing. Pre-
ventive safety measures reduce the risk
of injury.
• Store idle equipment out of the reach
of children and do not allow persons
unfamiliar with the equipment or these
instructions to operate the equipment.
Equipment can be dangerous in the hands
of untrained users.
• Maintain equipment. Check for misalign-
ment or binding of moving parts, missing
parts, breakage of parts, and any other
condition that may affect the equipment’s
operation. If damaged, have the equip-
ment repaired before use. Many accidents
are caused by poorly maintained equip-
ment.
• Use the equipment and accessories
in accordance with these instructions;
taking into account the working con-
ditions and the work to be performed.
Use of the equipment for operations differ-
ent from those intended could result in a
hazardous situation.
• Use only accessories that are recom-
mended by the manufacturer for your
equipment. Accessories that may be suit-
able for one piece of equipment may be-
come hazardous when used with other
equipment.
• Keep handles dry, clean, and free from
oil and grease. This allows for better con-
trol of the equipment.
Battery Use and Care
• Use equipment only with specifically
designated battery packs. Use of any
other battery packs may create a risk of in-
jury and fire.
• Recharge only with the charger speci-
fied by the manufacturer. A charger suit-
able for one type of battery pack may cre-
ate a risk of fire when used with another
battery pack.
• Do not probe battery with conduc-
tive objects. Shorting of battery termi-
nals may cause sparks, burns, or electri-
cal shock. When the battery pack is not in
use, keep it away from other metal objects,
like paper clips, coins, keys, nails, screws
or other small metal objects that can make
a connection from one terminal to anoth-
er. Shorting the battery terminals together
may cause burns or a fire.
• Under abusive conditions, liquid may
eject from battery; avoid contact. If con-
tact occurs, flush with water. If liquid con-
tacts eyes, seek medical help. Liquid eject-
ed from the battery may cause irritation or
burns.
• Do not cover charger while in use. Prop-
er ventilation is required for correct opera-
tion. Covering charger in use could result
in fire.
• Use and store batteries and chargers
in dry, appropriate temperature areas.
Extreme temperatures and moisture can
damage batteries and result in leakage,
electrical shock, fire or burns.
• Properly dispose of batteries. Exposure
to high temperatures can cause the batter-
ies to explode; do not dispose of in a fire.
Some countries have regulations concern-
ing battery disposal. Follow all applicable
regulations.

Product Overview
Description
ST-305/R is used to refer to both the
ST-305R and the ST-305 throughout this
manual. The ST-305R and ST-305 are
functionally identical. The only differ-
ence is the ST-305R can be used with a
rechargeable battery and internal C-cell
batteries. The ST-305 is only operational
with internal C-cell batteries.
The RIDGID®SeekTech®ST-305 and ST-
305R are compact yet powerful multi-fre-
quency transmitters that can be used, in
conjunction with a RIDGID SeekTech re-
ceiver, to find buried conductors such as
pipes, cables, and wires. This allows the
line’s location to be correctly marked so it
can be exposed for repair or avoided during

ST-305/R Safety
• Read and understand this operator’s
manual, and the instructions for any
other equipment in use and all warn-
ings before operating the ST-305/R. Fail-
ure to follow all instructions and warnings
may result in property damage and/or seri-
ous personal injury. Keep this manual with
the equipment for future use.
• Operating the equipment while in water
increases the risk of electrical shock.
Do not operate the ST-305/R if the opera-
tor or equipment are standing in water.
• The ST-305/R is not designed to pro-
vide high voltage protection and isola-
tion. Do not use where a danger of high
voltage contact is present.
• Always attach leads before turning
the ST-305/R on and always power off
the ST-305/R before disconnecting the
leads to reduce the risk of electrical
shock.
• Follow local guidelines and call before
digging. Locating equipment uses elec-
tromagnetic fields that can be distorted
and interfered with. More than one utili-
ty may be present in a given area. Follow
local guidelines and service procedures.
Confirm location of utilities before digging.
High Voltage Indicator
The ST-305/R is designed to withstand
up to 240 VAC between the two leads.
This protection is not intended to be
used continuously and excess current
may be forced through the ST-305/R. To
reduce the risk of electrical shock, do not
touch the transmitter, cords, or connec-
tions during this time. Use high voltage
precautions to disconnect the ST-305/R.
If the ST-305/R senses excess current, a
warning beep sounds and the High Voltage
LED on the keypad is lit.

Operation Overview
WARNING
Wear eye protection when appropriate
to protect your eyes against dirt and
other foreign objects. Follow operating
instructions to reduce the risk of injury
from electrical shock and other causes.
The default frequencies that come with the
ST-305/R are:
• 1 kHz [1,024 Hz]
• 8 kHz [8,192 Hz]
• 33 kHz [32,768 Hz]
• 93 kHz [93,623 Hz] or 262 kHz
[262,144 Hz]
Note: High frequency is 93kHz or 262kHz
depending on your region.
The ST-305/R has three operating modes
that can be used during a locate. Which
mode you use depends on the circumstanc-
es of the locate.
Direct Connect — The leads con-
nect directly to the target conductor
and a suitable ground.
Inductive Clamp — The optional in-
ductive clamp encircles the target
conductor when metal-to-metal con-
tact is not possible or unable to pro-
duce the desired result.
Inductive — The ST-305/R is placed
over a conductor. The internal anten-
na induces a signal on to the target
conductor.
Powering the ST-305/R
WARNING
Disconnect external leads from any en-
ergized utility before opening the bat-
tery compartment. To prevent overheat-
ing and leakage, do not mix battery types
or brands and do not combine new and
used batteries. Always remove the bat-
teries before shipping or storing the ST-
305/R.
Li-Ion 18 V Battery
A Li-Ion 18V rechargeable battery can be

Cable Lead Clips
The ST-305/R features cable lead clips that
can be attached mechanically or magneti-
cally. Before connecting the leads, use the
teeth on the clip to scrape off rust or paint.
When the metal is exposed you can either
clip onto the target with the teeth or use the
magnet to make the connection.
NOTICE
The cable lead clips con-
tain strong magnets. Do
not place the clips near data storage de-
vices, credit cards, or other magnetically
encoded data.

Direct Connect Mode
Direct Connect Mode is most commonly
used when the target utility is readily acces-
sible. Do not use Direct Connect Mode on
energized (live) conductors. The transmitter
is not designed to connect to live conduc-
tors.
1. Choose connection locations for the
ground stake and the target conduc-
tor. Place the transmitter, powered off,
on the ground between these two lo-
cations.
2. Insert the ground stake into the earth
as far as possible. Wet the earth
around the ground stake to improve
grounding and to lower the resistance
of the ground. With the ST-305/R still
powered off, attach the lead clip to the
ground stake.
Instead of using the provided ground-
ing stake, the lead clip can be at-
tached to other objects such as a
shovel blade or a metal rod sunk into
the earth. Using larger grounding ob-
jects may improve grounding by in-
creasing the surface area in contact
with the earth.
Note: Always connect the lead to the
ground stake before connecting an-
other lead to the target line to direct
any current within the target conduc-
tor away from the user.

ST-305/R – English – 13
3. At the target conductor, scrape away
any dirt, paint, corrosion, or other
coatings and attach the other cable
lead clip with either the teeth or the
magnet.
Good contact between the cable lead
and the target conductor lowers the
resistance of the circuit and produces
a stronger tracing signal.
Note: Non-conductive pipes, such as
those made of clay or plastic, cannot
carry a tracing current without a trace
wire. Plastic pipes typically have a
trace wire installed with the pipe for
tracing purposes. Clip the cable lead
to the trace wire to enable tracing.
Expanded Frequency Settings
While in Direct Connect Mode, the transmit-
ter can be used with high or dual frequen-
cies.
1. Long press (>3 seconds) the Fre-
quency key to set the transmitter
to high frequency.
2. Short press the Frequency key to
cycle through dual frequency options
or return to the high frequency. Ex-
panded frequency options include:
• 262 kHz or 93 kHz only.
• 33 kHz and 1 kHz dual frequency
transmission.
• 33 kHz and 8 kHz dual frequency
transmission.
The LED associated with each fre-
quency is lit when that frequency is
in use.
3. Long press the Frequency key
again to return to standard frequency
options.
Note: High frequency is 93kHz or 262kHz
depending on your region. Expanded fre-
quency settings are only available in Direct
Connect Mode.

14 – English – ST-305/R
Inductive Clamp Mode
Read the Operator’s Manual for the Induc-
tive Clamp before using it with the ST-305/R.
It includes important safety information and
operating instructions.
Use the ST-305/R with an inductive clamp
by following these steps:
1. Before connecting the inductive
clamp, confirm that the target conduc-
tor is not live and grounded on both
ends, and that the ST-305/R is pow-
ered off.The ST-305/R is not designed
to be connected to live conductors.
2. Insert the inductive clamp plug into
the jack on the ST-305/R below the
keypad.
3. Place the jaws of the inductive clamp
around the target conductor, ensuring
that they close completely. The LEDs
on the clamp are lit when the jaws are
closed and the ST-305/R is powered
on.
4. Press the Power key . The ST-
305/R automatically switches to In-
ductive Clamp Mode and disables the
cable leads.
Note: In Inductive Clamp Mode,
the ST-305/R defaults to 50 per-
cent power level to conserve battery
power.
5. Select and set the same frequency on
both the receiver and transmitter.
6. Check the connections and adjust the
current as needed during the locate.
7. When finished, press the Power key
to power off the ST-305/R before
disconnecting the inductive clamp.

ST-305/R – English – 15
Inductive Mode
Disconnect the lead clips from any external
conductors before switching the ST-305/R
to Inductive Mode. If the lead clips are con-
nected to an external conductor and the
ST-305/R is switched to Inductive Mode, a
warning appears and operator override is
required.
Do not use clips and leads in Inductive
Mode. The ST-305/R automatically sets the
frequency to 33kHz the first time Inductive
Mode is used. After the first use, the ST-
305/R automatically uses the frequency last
used in Inductive Mode. The two frequen-
cies available in Inductive Mode are 8kHz
and 33kHz.
NOTICE
Do not place two ST-305/
Rs in Inductive Mode
with the power on within
3m [10ft] of each other.
The output of each ST-305/R can over-
load the electronics and damage one or
both units.
Use the ST-305/R in Inductive Mode by fol-
lowing these steps:
1. Place the ST-305/R so the white ori-
entation arrows located on top of the
ST-305/R are aligned with the target
conductor.
2. Press the Power key to power on
the ST-305/R. Press the Inductive
Mode key to toggle the ST-305/R
between Direct Connect Mode and In-
ductive Mode.
Ground both ends of the utility for the
best signal induction.
3. To power on and use the receiver,
refer to the receiver’s Operator Man-
ual. Ensure the frequency on the re-
ceiver matches the ST-305/R. If the
receiver signal increases when held
near the ST-305/R, it is correctly pick-
ing up the transmitted frequency.
4. After completing the locate, press the
Power key to power off the ST-
305/R.

16 – English – ST-305/R
Air-Coupling
Any transmitter in Inductive Mode gener-
ates a field through the air around it; includ-
ing the ground underneath. If within air-cou-
pling range of the ST-305/R, the receiver
will measure this field instead of the target
conductor. Air-coupling will distort readings
and misconstrue the location of the target
conductor.
Air-coupling effects can dominate the re-
ceived signal over a wide range (great-
er than 20m [70ft]) if the induced utility is
deep and poorly grounded. Very weak in-
duction and deep utilities will result in great-
er air-coupling distances. Always confirm
the detection of utilities and the readings of
depth measurements.
Air-coupling does not depend on the output
power of the transmitter and cannot be re-
duced by turning down the power. Air-cou-
pling only depends on the ratio of the field
from the transmitter compared to the in-
duced field in the target utility.
The effect of air-coupling can vary continu-
ously so be aware of the difference between
the transmitter’s field and the induced field
of the utility being traced. While both will
have the same frequency, the transmitter’s
field is only strong enough to obscure the
utility’s signal in the region around the trans-
mitter itself.
Be sure to look overhead for power lines
that could also confuse the locate.
Testing for Air-Coupling
To test for air-coupling, tilt the receiver at a
45 degree angle towards the ST-305/R and
ensure the lower antenna of the receiver
touches the ground. Afterwards, tilt the re-
ceiver 45 degrees away from the ST-305/R
and observe the depth reading. If the depth
reading changes significantly, air-coupling
may be affecting the accuracy of the locate.
Alternatively, test for air-coupling by stand-
ing 6m [20ft] away from the ST-305/R. With
the lower antenna on the ground, take note
of the indicated depth measurement on the
receiver. Raise the receiver vertically 45cm
[18in] and observe the change in the depth
indication. If the receiver only reads the con-
ductor, the depth should increase accord-
ingly. If the receiver is air-coupling, the depth
indication does not change by 45cm [18in],
but changes disproportionately.

Locating
WARNING
To reduce the risk of electrical shock,
power off the ST-305/R before discon-
necting the leads and remove the lead
from the target conductor before remov-
ing the lead from the ground stake.
Note:When the ST-305/R is powered on and
in Direct Connect Mode,only hold the cable
leads by the plastic sheathing. Do not touch
the metal scraper tip, teeth, or magnet.
1. With one cable lead attached to the
ground stake and the other attached to
the target conductor, press the Power
key to power on the ST-305/R.
Upon start up, the ST-305/R mea-
sures the current flowing through the
target conductor and beeps to indicate
output. Faster beeps indicate a higher
output current.
2. Select a frequency by pressing the
Frequency key until the desired
frequency is selected. Long press (>3
seconds) the Frequency key to se-
lect the expanded frequency option for
dual or high frequencies.
3. Follow the instructions in the receiv-
er’s Operator’s Manual to power on
and use the receiver. Ensure the fre-
quency on the receiver matches the
ST-305/R. If the receiver signal in-
creases when held near the ST-305/R,
it is correctly picking up the transmit-
ted frequency.
4. After completing the locate, press the
Power key to power off the ST-
305/R.
