Metal detectors with high sensitivity have problems with false signals. It is a price to pay!

I just finished the PCB. If there is an interest I will share it.

I think that pads for 4.7 microF are too small, better wil be a larger pad, maybe a 7.5 or 10 mm pad.
Only my opinion,because it's difficult find so large capacitor with a case like a 100nf capacitor

I still haven't made this device, and that`s why I don`t have the exact coil data. I only made PCB of the schematic, posted by its author in post #1.
Concerning the 4,7 uf - I intend to use two polar 10uf capacitors connected in series if non-polar 4,7uf capacitors with a suitable size are not found.
