Unfortunately, the requirement for this board is English only so the document in the Zip file is contrary to that. Also, there is no schematic. The numbers you cite are impressive.

It's all about that moment when metal that hasn't seen the light of day for generations frees itself from the soil and presents itself to me.

I don't know what this detector is meant to be used for But the Delay is too High for small Gold and the frequency seems too low, with these specs it appears to be set up just for coin hunting.

There are 12 pages 281 posts under the name felezjoo pi
and the topic is growing on geotech.
But none of the builders successfully reproduced it as yet.

better is to make Clone PI with free of charge HEX code. no trial, no demo HEX with 300 attempts of turn on's.

If the target was a US quarter (diameter 24.26mm/0.955 inches) with a 10 inch coil
In mineralized ground 1.1 meters it’s ALLOT
If your target was a Volkswagen beetle on open air then you are right.
Can you give us more info about the detector, especially how performs on mineralized ground or salty wet sand?
How difficult was to build and perhaps some pics of what you did?
