... while it is true that the DFX has numerous excellent features which, IF USED, make it a somewhat better coin and jewelry detector then the MXT, several points in favor of the MXT need to be considered. First off, the MXT is far easier to learn, and operate, then the DFX. For some, this is a serious consideration. I know of one White's dealer who reports having MANY TIMES traded new MXT's straight across for as-new DFX's, because the owner "found the DFX too complicated." And he reports that NONE of those folks ever asked to trade back. Another factor in favor of the MXT is that it is a vastly better gold prospecting detector then the DFX. My own personal tests, in the actual Mojave Desert goldfields, reveal that the DFX, optimally tuned for small nuggets, and fitted with the stock 950 coil (the exact same coil as on the MXT) can find nuggets as small as 7 grains in weight. The MXT can find flakes as small as 1/4 grain. Obviously, there is a world of difference there. From my own personal experience, I figure I find 50 to 75 nuggets (and flakes) LESS than 7 grains for each 7 grain or larger nugget I recover. It is for this reason that, on the West Coast (i.e. "gold country") sales of the MXT far exceed sales of the DFX. Then, too, there is the economic isue: the $300.00 difference in price between the DFX and MXT can buy such things as accessory searchcoils and high performance headphones, thus greatly enhancing the versatility of the MXT. The astute detectorist takes the needed time to carefully ascertain his or her needs, and chooses the machine best suited for their particular needs. For some, that machine will be the DFX. For others, it will be the MXT. For yet others, it will be the Prizm II. "To each his own." Jeff, your comments and insight are VERY much appreciated, and have been helpful to many. Keep up the good work. Happy Hunting! Jim
