The SeekTech ST-510 Line Transmitter lets you energize metallic lines for tracing with a locator.

The RIDGID SeekTech ST-510 line transmitter is part of the RIDGID SeekTech cable and pipe locating system. The ST-510 is used to generate an “active” signal on a metallic underground line so that it may be traced with a compatible receiver such as the SeekTech SR-20 or SR-60. This allows the line’s location to be correctly marked so it can be exposed for repair or avoided during excavation.

The ST-510 line transmitter can apply an active tracing signal to a target conductor in three ways:

Direct Connect Method – The transmitter’s leads are connected directly to the target conductor and a suitable ground (See page 8).

Inductive Clamp Method (optional accessory) – The jaws of the inductive clamp encircle the target conductor; there is no metal-to-metal contact.

Inductive Mode – The transmitter is placed over, and in-line with, a conductor. Its internal antenna induces a signal onto the target conductor.
