to read into the ground just a few inches.

The circuit with PIC is very cool. This looks like a good place to start.
I'd like to write my own code. Maybe it would be possible to block
certain metals like aluminum and iron from being detected.
This way somebody doesn't keep digging up trash.

Any idea why yours only has a few inches of depth detection?

Wonder if the pick-up coil senstivity can be increased/decreased.

Thanks again Locko, this has been a huge step in the right direction.

I know nothing about the BFO detector. I just heard about metal detector and gold detector.
