The kind of metal detector we have built is based on pulse induction (PI). PI systems may use a single coil as both transmitter and receiver, or they may have two or even three coils working together. This type of metal detector sends powerful, short bursts (pulses) of current through a coil of wire. Each pulse generates a brief magnetic field.Web
