The Gold Monster is sparking my interest in VLF to supplement my detecting arsenal.
But I have a question - what exactly does a discriminating machine discriminate out?
I am assuming ferrous and non-ferrous, which in my simple terms means magnetic and non magnetic. Please correct if wrong.
So on the iron/ferrous side do we have - nails, tin, bottle caps, metal buttons, please add things in here. Where do meteorites fit in?
On the non ferrous side we obviously have gold. B
Short answer - it is fairly easy to separate ferrous from non-ferrous, and that is what many prospecting machines attempt to do. There is no way to reliably tell one type of non-ferrous metal from another non-ferrous metal, so you have to dig all the lead bullets, aluminum, etc. to get the gold. Now some details.
Metal detectors are electromagnetic devices. They therefore "see" items that can either conduct electricity (are conductive) or have magnetic properties, or both together.
