IMO, you sure repeated Cibola (or Cybola?) Tesoro detector. let it will be tags for future requests. i regularly get same in Messages, to share HEX and schematics of CIBOLA.
that i have not certainly in the Archive.

Thanks for posting this project. I am very interested in doing something similar with the Raspberry Pi Pico so your schematics and results are just what I need to jumpstart my own project. I already use the Pico quite a bit for other hobby projects so it only makes sense to pick that as my microcontroller of choice. I'm anxious to hear if you have any other updates to share: what has worked well and what hasn't.

I think this is a very interesting project and I'll keep my eye on it.

Thanks for your kind words. I have no further updates at the moment but intend to do a lot more field testing once the weather warms up a bit and I'm sure I'll find quite a bit to improve upon then.

I find that it's quite tricky to wind and balance these coils so I've bought a coil from Aliexpress (Link below) to try.

hi Olly
How did the coil from AliExpress work out?

Hi Paul,

Sadly, I haven't gotten around to trying it out yet. I came out of retirement to take on a fairly long-term consulting project so when that is done I'll hopefully get back to metal detectors again.
