Abstract
A system and method for locating a break in a single conductor unshielded wire is provided. The system includes a transmitter generating two continuous wave radio frequency signals attached to each of the wire segments of a broken wire. Each signal has a unique frequency and is transmitted in opposite directions around the wire. When a locator is operated near a wire transmitting one of the signals, an audible tone of the appropriate frequency is generated. The volume of the tone decreases as the locator is moved closer to the break. In this manner, the operator can determine the location of the break within a margin of about six inches. Accordingly, no unnecessary digging is required to locate the break in the wire.
