GOLD SEEKER DEVICE. Gold seeker with Pulse Induction System. Gold seeker device powered Pulse Induction System. The system is the easiest to use and the latest and most accurate to detect gold, gold nuggets, rough gold and ancient coins in the ground. Gold seeker is a system that discriminate between precious and non-precious metals.
Pulse Induction (PI) metal detectors are sending repeated pulses of electrical current to the search coil, producing a magnetic field. The coil transmits a pulse toward the ground, generating an answering pulse from the target object. A sampling circuit measures the pulse and sends it to an integrator, which generates an audio tone.
