Claim Text:
1. In a system for locating an in-ground cable in a region using a cable locating signal which is transmitted from the length of the cable, a walkover locator comprising: a receiver for sensing a signal strength of the locating signal at an operator determined distance above a surface position on the ground; a sensor for measuring the operator determined distance above the surface position; and a processor cooperating with the receiver and the sensor for accepting a first signal strength measured at a first operator determined distance at least generally vertically above the surface position, which surface position is not directly overhead of the cable, and a second signal strength measured at a second operator determined distance at least generally vertically above the surface position and for determining a depth of the cable using the first and second signal strength measurements and the first and second operator determined distances.
