A typical PI-based metal detector sends about 100 pulses per second, but the number can vary greatly based on the manufacturer and model, ranging from a couple of dozen pulses per second to over a thousand. If the metal detector is over a metal object, the pulse creates an opposite magnetic field in the object. When the pulse's magnetic field ...
