High-Output Line Transmitter

SeekTech ST-510

Higher-output transmitter with variable power and an LCD display providing feedback on line resistance and current flow during direct-connect locating work.

Maximum output 10 W
Line trace frequencies Multiple
Display LCD circuit feedback
Signal & Sonde Accessories

Different Ways to Introduce a Detectable Signal

Where a service cannot simply be traced passively, RIDGID accessories can help introduce or position a signal that can then be detected from above ground.

RIDGID SeekTech inductive signal clamp
Transmitter Accessory

SeekTech Inductive Signal Clamp

Applies a transmitter signal around a suitable cable or metallic pipe where making a direct electrical connection is difficult or impractical.

Particularly useful where access to the conductor is available but a conventional direct connection is not appropriate.
RIDGID 512 Hz remote transmitter sonde
512 Hz Sonde

RIDGID Remote Transmitter

A 512 Hz transmitting sonde that can be attached to compatible drain-cleaning cables or water-jetting hoses so its position can be located inside a drain or pipe.

Useful for pinpointing the position of a blockage, camera, cable or hose from above ground.

Need sondes for Cobra Rods or Flexitrace?

Rausch UK also supplies dedicated 33 kHz, 8 kHz and 512 Hz rodding sondes for non-metallic pipes and ducts.

How Utility Locating Works

From Signal to Position

The equipment you need depends on what is underground and how you intend to create or identify the signal.

1

Identify or Introduce a Signal

Locate an existing passive utility signal or apply a known frequency using an ST-305, ST-510, inductive clamp or transmitting sonde.

2

Trace or Pinpoint

Use a compatible RIDGID receiver to follow a buried line or identify the position of a sonde inside a pipe, drain or duct.

3

Mark or Record the Location

Mark the route on site or, with the SR-24LE, integrate locating information into a more connected digital mapping workflow.

Choosing a System

Which RIDGID Locator Should I Choose?

Start with what you normally need to locate and whether digital mapping forms part of your field workflow.

Drainage & Sonde Work

NaviTrack Scout

A strong choice where the main requirement is locating sondes, inspection camera transmitters and known underground lines in drainage applications.

Choose it when: sonde and camera locating is your main day-to-day requirement.
Professional Utility Tracing

SeekTech SR-20

A broader professional utility locator for regular active, passive and sonde locating across underground cables, pipes and utility networks.

Choose it when: you want a dedicated professional utility locating platform.
Locating + Digital Data

SeekTech SR-24LE

Adds GPS and Bluetooth connectivity to the SeekTech locating platform for users who need location data, connected workflows and digital mapping capability.

Choose it when: locating data needs to become part of a digital record.
From Location to Inspection

Locate the asset. Then inspect its condition.

RIDGID locating equipment helps identify and trace buried utilities. Once the route and access point are established, CCTV inspection can provide the next level of information by showing what is happening inside the pipe.

1
Locate

Find the underground asset

Use RIDGID locating equipment to identify the route and position of buried pipes, utilities, sondes and inspection equipment.

2
Access

Establish the inspection point

Once the asset has been located, identify the most suitable access point and understand the pipe size, route and inspection distance.

3
Inspect

See what's happening inside

Rausch push-camera and crawler systems can then be used to assess pipe condition, identify defects and investigate the cause of a drainage or sewer problem.

The Next Step

Need to inspect the pipe you've located?

For smaller drains and accessible pipework, a Rausch push-camera system may be the right starting point. For larger pipes, longer distances or powered inspection, explore the Rausch crawler range.

Frequently Asked Questions

RIDGID Utility Locating FAQs

Common questions about choosing and using RIDGID underground locating equipment.

What is a RIDGID utility locator used for?
RIDGID utility locators are used to detect and trace underground utilities or transmitted signals. Depending on the equipment and application, this can include metallic cables and pipes, passive utility signals and transmitting sondes inside drains or ducts.
What is the difference between the SR-20 and SR-24LE?
Both are professional SeekTech utility locating receivers. The SR-24LE adds integrated GPS and Bluetooth Low Energy, making it better suited where field locating also needs location data, connectivity or digital mapping.
What is a line transmitter used for?
A line transmitter applies a known frequency to a suitable conductive cable or pipe. A locator set to the same frequency can then detect the signal from above ground and help trace the route of the service.
Can RIDGID locating equipment find plastic pipes?
A non-metallic pipe normally needs a detectable signal to be introduced into or alongside it. This can be achieved using equipment such as a compatible sonde or tracing system. Rausch UK also supplies rodding sondes and Flexitrace equipment for this type of application.
Should I choose the ST-305 or ST-510 transmitter?
The ST-305 is the more compact 5 W transmitter and can transmit two frequencies simultaneously. The ST-510 provides up to 10 W variable output and includes an LCD showing circuit resistance and current information. The right choice depends on the type and distance of the locating work.
Can the RIDGID Remote Transmitter be used inside drains?
Yes. The RIDGID Remote Transmitter is a 512 Hz sonde designed to be attached to compatible drain-cleaning cables or water-jetting hoses so that its position can be located from above ground.
