My White's CM-2, 1964 model beat frequency oscillator (BFO) detector that I still enjoy using, something soothing about the motorboat sound, and despite the bad press they get better depth than recognized, even with the smaller coil. The small coil on this one will sniff out coins 6" deep in wet soil. Swap out to a larger coil, and get big stuff a couple of feet deep, and with time and experience these will speak to you in their own language, whereas it will locate the metal object and you become the discrimination unit, hard to explain. They will detect American paper money, the bigger the wad, the better the signal, due to the metal in the ink on our folding money, try that with your VLF. Put a coin on a sheet of steel, balance out the steel, and it will detect the coin. Lots of caches found with these in the old days as the machine wasn't smart enough to tell the operator that the big signal he was getting was trash and should be avoided, and they found lots of rusty cans that contained nice treasures. Very good for searching walls and floors in old houses as all those nails don't bother it. Gives a low tone on ferrous objects, and a higher tone on copper & silver, also the best machine to use if high grading old gold mine tailings, and can locate black sand deposits in mineral mode. It will also send you to the doctor if you swing that beast too long. Not much for ergonomics with that handle, and the weight is about on par with a high powered hunting rifle without the balance.
I use it in scout mode on a new sight to kind of sniff around a bit, then when my wrist and arm can't take it anymore I swap over to my newfangled whippersnapper Bounty Hunter 202, that youngster is only about 20 years old, and thinks it knows everything!
My AT Pro will be taking a nap for a while, once I get the Quest Pro.... gotta see what that's all about.
