Metal detectors are categorized into four groups based on their operating principles, beat-frequency, oscillation, and resonant frequency oscillation.

These are the two early techniques used in metal detectors.

Detectors based on these principles are not preferred due to frequency stability issues. Induction balance (IB) and pulse induction (PI) detectors are more widely used.

Pulse Induction (PI) is a type of metal detecting technology. A pulse induction metal detector operates by sending short pulses of voltage to the metal detector coil. These short pulses cause a magnetic field to be generated, which quickly dissipates at each pulse’s end.

Any metal targets that induce the magnetic field remain magnetized for a short time after the end of a pulse. The detector’s coil then detects the target’s decaying magnetism.

A pulse induction metal detector can deal more effectively with much more complex, variable ground conditions; this is the reason a pulse induction metal detector works so well for gold detecting, and pulse induction machines are excellent for working the beach and searching for gold nuggets.
