Abstract

1,087,216. Locating conductors. M. I. HOWELL and A. J. MORRISON. Aug. 9, 1966, No.22207/66. Heading G1N. Portable apparatus for locating a conductive body comprises a spar having at the lower end a transmitter coil with its axis along the spar and energized from a low-frequency transistor oscillator. At the other end of the spar is a receiver coil with its axis at right angles to the spar and connected to an amplifier with an indicating meter.
