It seems finding these little buggers are like finding hen's teeth. I visited a very reputable local coin dealer and obtained a type1 $1.00 1852 gold coin for testing purposes. For those who don't know, this is the smallest coin the U.S. has ever minted. It's about ½" in diameter.
The Nokta Core is sort of a pain to test because it tries to up convert the TID numbers. So the Nokta with 5" coil would give a solid 2 way signal at 4" but the TID would increase the further away the coil is.
Nokta Fors Core with 5" coil air test and on the ground same results: DI3 mode.
U.S. $1.00 Type 1 gold coin TID 54-60 Max depth about 6"
U.S. Nickel TID 55-61
EuroTek Pro w/8" concentric coil:
U.S. $1.00 Type 1 gold coin TID 55 Same depth as Nokta
U.S. U.S. Nickel TID 56.
On both detectors the gold coin came in just under a U.S. Nickel. So if you want to find these coins you must dig Nickel sounds and TID numbers.
