It's called a pinpointer. It puts a pulse on the line that goes to ground at the fault. The pulse radiates out from the fault (picture the ripples from throwing a pebble on a pond). The sensor that picks up the signal has two probes usually marked red and black. Placing the probes in the ground the probe that picks up the signal first will be indicated. Moving the probes in the direction of the indicated probe in a football chain fashion until the indicator picks up the opposite probe then narrowing down the distance between probes until the fault is "pin pointed". The pinpinter we use is manufactured by H.J. Arnett. It sounds simple however sometimes it takes you right to the fault and sometimes it sends you on a wild goose chase to a ground rod or telephone splice or whatever.
