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.

I call this "Pulse oscillation decay" type detector or just "Pulse oscillation" detector. In principe it is inspired by commonly known pulse induction detectors. Current pulse is sent to the coil and then response is measured. In my detector circuit the coil is not dumped by dumping resistor as found in common pulse induction detectors.
