RIDGID SeekTech ST-305R: The Powerful & Flexible Multi-Frequency Transmitter

February 1, 2021

The new RIDGID SeekTech ST-305R is a compact yet powerful multi-frequency transmitter that is compatible with any RIDGID SeekTech or NaviTrack receiver 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 excavation.

The ST-305 and ST-305R are functionally identical. The only difference is that the ST-305R can be used with an 18 V Li-Ion rechargeable battery and internal C-cell batteries while the ST-305 is only operational with internal C-cell batteries. Thus, the ST-305R boasts flexibility when it comes to power options, allowing minimal interruptions on the job.

Featuring three operating modes, the ST305-R can apply an active tracing signal to target a conductor directly using the metallic leads, inductively with the internal antenna, or with the optional SeekTech Inductive Clamp accessory. It also essentially transmits two frequencies simultaneously to allow optimal frequency selection. Check out below its other key features:


Low, medium, and high frequencies from 1 to 262 kHz are available


Designed for use with any SeekTech or NaviTrack receiver to trace and mark the positions of buried pipes and cables


Lightweight, compact transmitter that delivers up to 5 Watts of power


Confirm a good circuit before beginning a trace
