I never knew, but … found out a few things by Googling … like …. this article

I’d definitely recommend testing, testing, and re-testing it, before counting on it.

All you’d have to do to test it is … shoot a (known ferric) brad into a board, clip it off at the surface, and clamp another board on top of the first board (that has the brad in it, clipped off at the surface).

You could vary the thickness of the 2nd board, but … that’s how I’d test it.

Preferably, you’d test it against a known working actual metal detector, if you have one. This would give you a way to find out if it works, how well it works, and whether it has enough sensitivity to do … what YOU need it TO do: find metal in lumber that YOU’RE likely to check.

But my gut says … it’s software, in hardware, and … that means … it could easily fail, and—of course—only at the worst possible time.

And how would you know if it DID fail, unless you kept your test board(s), and checked it EVERY time you were going to use it ??

Good post, and good luck !
