SeekTech ST-510

The RIDGID SeekTech ST-510 (21903) Pipe and Cable Line Transmitter (10 Watts) 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.

Inductive Clamp Method (optional accessory): The jaws of the inductive clamp (sold separately) 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.
