How is your metal detector design circuitry similar to or different from commercial designs? What commercial detectors are available in Russia? I have been using White's Electronics machines for many years and never really thought about the guts that make them work. Wish I had learned more electronics in school, this is super impressive work you are doing, congrats!

Although the principle of operation of pulse metal detectors is the same, their designs are very diverse. I tried to make the metal detector as simple as possible (one gain stage on a conventional op amp, integrator and filter are implemented in software, on a not too powerful microcontroller with no outstanding ADC), but nonetheless possessing acceptable characteristics.

My native language is russian, but i live in Belarus now. In our country, metal search is very limited at the legislative level.
