Excellent discrimination; struggles in highly mineralized soils. (Pulse Induction)

The schematic is drawn in classic, hand-routed PCB style, complete with part numbers (LF353 op-amps, IRF740 MOSFETs) that are still available today.

: If metal is near, the induced eddy currents delay the decay of this voltage spike.

The textbook explains that all metal detectors rely on . A transmitter coil creates a dynamic magnetic field. When this field encounters a conductive metal target, it induces small electrical loops called eddy currents within the object. These eddy currents generate their own secondary magnetic field, which is subsequently captured by a receiver coil and translated into an audio or visual signal by the control circuitry.
