Thanks Pito...

oh sorry I forgot to say that the piece of metal is about the size of a coin

I would add two things:
1) Those who approach the world of metal detectors for the first time often only look for depth;
2) A meter of depth for a single coin is a utopia with current technology.

Better to look for good discrimination, a ground balance that works, in short a good detector that does not give false signals.

Among the projects published on this site there are some decidedly good ones to realize bringing home excellent results at a low cost and above all the satisfaction of having managed with your own means to realize a detector, learning many things.

I recommend buying Carl's book.

Sorry but i need depth because i dig everything , my land is spécial , almost nothing under 30 inches .

... more depth is the never ending quest because it means you can go over the ground that detectors with less depth have already covered.

Here is the formula ...

MORE DEPTH = NEW GROUND

Has anyone built this project. If so, did it work as expected?
