ABSTRACT OF THE DISCLOSURE An instrument for locating the position of hidden live continuous or broken wires utilizes an indicator such as a series of light emitting diodes to indicate the adjacency or the strength of the electrostatic field surrounding the wire. By watching the number of light emitting diodes lit, the instrument can be brought directly to the wire. The instrument is comprised of an antenna connected to the high input impedence of an amplifier, a low pass filter connected to the output of the amplifier, a lamp operation circuit and an indication means connected to the lamp operation circuit.
