Dave, tonight, I will post pictures, and they will speak for them selves. I was in the past shying away from DOC's forum, only because of the political post, now it has returned to a very good gold forum! And I hope I can help it stay that way. There is so much that we don't know about the coils and new equipment being developed, over the last couple of years, I hope to kind of put the word out as we say here in the states, to let everyone know. You do have other options as far as coil choises, besides the DD and mono coils. I think its great, my old 2200 having the way to hunt under power lines, My friend with a GP, could do so some what by switching to the RX mode on his detector, but that still did not take care of it all. But with the AI coil maybe it would, I just don't know. But today is the Day, like Mel Fisher use to say. I will find out just how well it does at least in that area, and I have a couple of more I want to try. Just so you know, I don't work for DOC or ROB, but Rob and I have gotten to be friends over the years, Rob sent me the Platypus to test, and I have the wet country up here to give it an honest try. I would not give that coil up, as a matter of fact, a friend asked me tosell it to him, as he has been detecting with me almost everytime I have found gold with it. I said NO, but you can order one from ROB or Doc. I hope the AI coil does as good. You will find out some reports tonight. GRubstake
