Recently purchased a XP ORX with Ellipitical HF coil. Noticed not much depth. I air tested with not to good results. Half dollar getting most depth. 1 Gold was 7", 2 Gold was 5", 3 Coin was 6", 4 Coin was 6". Factory settings. Is this what is to be expected ? Should I have chosen one of the other coils ?
Thanks !
