Abstract
A pulse-induction type metal detector using a transmitter coil energizing pulse that selectively reduces the amplitude of background signals from conductive soils, ores and salt water. The detector can be operated with higher amplification of the received signals than conventional detectors, without driving the input amplifier into saturation. This makes it possible to detect land mines, tramp metal and gold in media whose characteristics make detection with conventional metal detectors difficult.
