Metal detector with meter discriminating

coil data

Sasho, that's a very interesting design. Could you provide a little more information on the transmit coil? Are all three windings wound right on top of each other? How are they phased, where do phase dots go?

It seems that you have made many projects!
And this look interesting,but please give PCB layouts!I have tryed to make some PCB layouts,but I cant understand too many things!
This is new hobby for me.Please HELP!
Its inposible that you have made this and you dont have PCB layouts.
And what diodes you use as D5 and D6?
Thanks

Mistakes:
Meter is -0.05ma zero +0.05ma.Change + and- in schematic.
Sorri.

This is my schematic from 1992 year. Works better from many modern detectors:
