Thanks for the replies, I am swaying to the TDI as it seems possible to coin shoot with it, that would make it a bit more of an all round PI detector. I do like the PI detectors although the iron infested beaches here get a little tedious at times with the sea hunter. When I lived in the UK I used to own the Goldscan 2 PI detector it had a monstrous control box that you slung around your neck but it was a deep seeking machine. Thanks for the info guys as I said an excellent forum, who knows you guys might inspire me to get my Gold Pan out.
