RIDGID 14818 NaviTrack Line Transmitter.

The NaviTrack line transmitter is part of the Navi Track cable and pipe locating system. It can be used to energize a pipe or line, so that the magnetic field lines emitted from the underground line, may be traced. This aides in allowing the ground above the line to be marked so that it can be avoided during a dig, or so it can be exposed for re-pair or replacement. Underground lines can be energized with the Navi-Track line transmitter. This active signal is then traced using the NaviTrack receiver.
