Metal detector circuit

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.

Garrett Infinium LS - Steve's Reviews

 · Wave the coil over a target and adjust the headphones for a comfortable sound on the loudest targets. Then tweak the threshold for a barely discernable tone. Pulse Induction (PI) detectors have extremely sensitive receiver circuits. This means that they are much more prone to picking up outside electrical interference than standard metal detectors.

US5414411A - Pulse induction metal detector - Google Patents

Metal detector apparatus includes an increased pulse transmit frequency and reduced integration time constant for rapid target response and improved sensitivity to low conductivity metals, including cupro-nickel alloys, platinum and gold. Resistor-capacitor (RC) coupling totally eliminates the need to reset the controls due to changes in temperature or mineralization in the area being searched.

english Metal detector

was a simple metal detector. Later, I built various different metal detectors from plans published in electronics magazines. Today, the prices for metal detectors vary from a few hundred to a thousand Euro, and therefore I have decided to design one of my own – an improved version of the “pulse induction” metal detector.

Metal Detectors - Your Hobby Hour

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.
