Metal Detector using a 2 Pulse Induction Coil

2006-10-24  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. When the pulse ends, the magnetic field reverses polarity and collapses very suddenly, resulting in a sharp electrical spike. This spike lasts a few microseconds (millionths of a second) and causes another current to run through the coil. This current is called the reflected pulse and is extremely short, lasting only about 30 microseconds. Another pulse
