Ridgid SeekTech SR-20 w/ ST-305 Transmitter (5 Watt)


The RIDGID SeekTech SR-20 Utility Line Locator is a precision utility locating instrument with GPS and Bluetooth technology for easy integration with external data capture devices, including smart phones, tablets, and high precision GPS instruments.

The SR-20's omnidirectional antennas capture the complete signal field, making it easy to acquire the signal and trace its path. The receiver displays the utility's position and direction on the display, providing an intuitive locating experience.

The RIDGID SeekTech ST-305 Pipe and Cable Line Transmitter (5 Watts) is used to energize a pipe or line with an "active" electrical signal, so that the underground line may be traced with a compatible receiver (such as the SeekTech SR-20). This allows the line's location to be correctly marked so it can be exposed for repair or avoided during excavation.

The ST-305 line transmitter can apply an active tracing signal to a target conductor in three ways:

Direct Connect: The transmitter's leads are connected directly to the target conductor and a suitable ground. The ST-305 line transmitter is capable of dual-frequency transmission (sending two frequencies onto a line simultaneously) in direct-connect mode.

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

Inductive Mode (internal coils): The transmitter is placed over and in-line with a conductor. Its internal antenna generates a dipole field which energizes the target conductor below ground, inducing a current into the target conductor.
