AKS Gold detector - find gold up to a distance of 5km..... wtf, scam

[Deodand2014]

You can always build your own, this schematic dates from 2004, guaranteed to find even microscopic amounts of gold, which is why when you dig you'll end up with an empty hole in the ground...

Even better!
The last paragraph of that page is a gold nugget  :

If no obvious target is found when you reach 200 feet, then the target was most likely subatomic gold particles - you cannot see it and most chemical analyses will not detect it either, but the MFD will.

I'm pretty confident that with its help one will be able to dig out protons, neutron and electrons in various combinations.
