Hey guys, I've been lurking for quite a spell and am active other places and now this one too! I'm looking for a new relic machine after Christmas and was wondering if any one has had any experience in comparing the Troy X5, Fisher F75, Tejon and the Nautilus DCM IIB & IIba. I feel I that any of these machines would probably be a good choice, but I would like the best choice for my area which is North /Central Alabama with Medium to heavy mineralization containing red clay and iron in some areas. Thanks for any help. Tim
