Golden, I totally agree, although I haven't used the DFX either, I think we need to look at the whole package, and not just the sweep speed. We can set the sweep speed up with the high setting on Quatro, with a little reduced accuracy, but to me it goes plenty fast, even at the slower normal setting, and if you put on a smaller coil, it's super fast. I'm just speaking my mind here, but also from my own experience with my Quatro. When you consider the depth, very accurate notch able discrimination, ground problems (being virtually eliminated) and the ability to put on a small coil that will "pick out darn near any target you want". What more could you want? Marc.
