PI Schematic or kit with frame coil

[Metallsucher]

Hello,
I am looking for a schematic or kit for a PI metal detector that can work with a frame coil 1m x 1m.
It should have the location signal with an analog display (meter) and a click rate, which when idle works with a click at some khz by a strong signal.

I would be very happy about your suggestions.

Best Regards

Wolly

Usually, amateur pulse detectors work at a low frequency - Hz. In addition to delta pulse, the Polish development AVT 5196 is also suitable for amateur search.My advice is to look for a project with a verified schematic and a verified board.
