Thanks GP. Being such a newby I am digging every target. The At Pro gives a quieter signal the deeper the target in Pro mode. Makes it hard to pick them up. As I write this I am thinking in Standard mode it gives the same volume no matter the depth. Hmmm. Guess I'll try standard mode next time, or switch between the 2. There ya go, I just learnt something. The deep coins, either goldies or 20 and 50 cents ring up low numbers around 40 which would be foil etc normally.
