ABSTRACT:
A probe (10) for locating a buried cable (12) includes a casing (16) adapted to be driven into the earth (14). Situated in the casing is an RF receiver (23) for sensing RF energy radiated by the cable to establish the cable's approximate location. The casing also has a viewing window (19) in its lower tip (18) in optical communication with a television camera (30). The camera allows the cable, once its approximate location is established by the RF receiver, to be visually identified.
