RIDGID SeekTech 46918 Underground Utility Locator Kit — SR-20, ST-305 & Signal Clamp

A matched receiver and transmitter package for underground pipe and cable tracing.

The RIDGID SeekTech 46918 utility locator kit combines the SR-20 receiver, ST-305 line transmitter, and an inductive signal clamp. Apply a tracing signal to a conductive pipe, cable, or tracer wire, then follow its route with clear visual guidance from the SR-20.

Key Features

  • SR-20 locating receiver: Mapping display, guidance arrows, signal strength, and depth readings help you follow the target utility.

  • Distortion feedback: Helps identify interference that can affect locating accuracy.

  • 5-watt ST-305 transmitter: Provides adjustable signal output and can transmit two frequencies simultaneously.

  • Audible circuit feedback: Helps confirm the transmitter connection before tracing.

  • Inductive signal clamp: Applies a signal around an accessible conductor without a direct metal-to-metal connection.

  • Multiple tracing methods: Supports direct connection, clamp application, and induction.

  • Additional receiver modes: The SR-20 also supports passive locating and compatible sonde locating.

Built for Pipe and Cable Locating

Use direct connection when a suitable connection point is available, or the included clamp when direct contact is impractical. Match the transmitter and receiver frequencies before tracing.

The ST-305 also offers 262 kHz, but this frequency is outside the SR-20 receiver’s supported range. Non-metallic pipes require a traceable conductor or a compatible sonde; sondes are sold separately.
