Without trying to start a firestorm in this thread, I nevertheless stick to my guns about the DFX vs. the Explorer. I've had the DFX for a long time, have futzed with it every which way to get it to go deeper, even buying Jeff Foster's book and following his recommendations as well as trying the late Dave Z's suggestions over on the DFX Classroom, and still...dimes elude the DFX if they are deeper than 4" or so. Once, for some reason, I found a silver dime at about 7", but that was it. All of my old silver coins were found at relatively shallow depths, whether at the beach or inland. I bought a large Jimmy Sierra aftermarket coil which was supposed to increase depth, but found that it actually wouldn't go as deep as the stock coil. What a waste of $250.00. Acquaintances of mine who own Minelab Explorers routinely find deep, deep old silver and copper coins in areas I've searched with much less success. Look, I'm not saying I haven't found good stuff with my DFX. As one poster put it some time ago elsewhere on TreasureNet, the DFX is designed to suck up good targets quickly and easily, but time and time again I have witnessed that the Minelab just goes deeper and, moreover, "sees" more of the ground than the DFX at greater depths. Perhaps in other areas, in other soils, the DFX may perform differently than it does in my neighborhood. But I know what I know. No one who has purchased a DFX, or any other machine for that matter, need rankle at my expressed preference for the Minelab. Maybe the Minelab is a pain to use. Maybe the learning curve is ridiculously complicated. I don't know. I've never used one. All I know is what others who own one have found over the years, such as seated liberty half dollars at a foot down, and dimes at nine or ten inches. Seeing is believing, and I've seen, and I believe.
