Abstract:
A method of locating a buried conductor such as a pipe uses an electronic transmitter to generate a signal having a predetermined frequency with is applied to the pipe via an alligator clip or other appropriate connector. A ground connection to the transmitter is established by connecting another alligator clip or other appropriate connector to a grounding sheet made of chain mail or metal cloth. A electrolyte solution is poured on the grounding sheet and/or around a portion of the surface region adjacent the grounding sheet. The signal that is re-radiated by the buried pipe is detected with a man portable locator which determines the location of the buried pipe and displays the same to a user.
