it is truly amazing. At first I ran in the pre-set programs and managed a couple of nice silver rings and mercs and such, but once I learned how to adjust and tweak the programs I was shocked at the coins I started finding. Almost every place I hunt has been pounded and my finds are truly shocking of how much silver is still left. I had found over 16 seated coins this year (four quarters), numerous barbers and countless mercs and roosies. I averaged silver almost every time out this year. I even managed to find my first and second gold ring, my first large cent and my first spanish reale. The relics I have found have also been great (A dragon from an indian trade rifle, trade ax and a few buttons). This machine with its flexibility and adjustably has never given me a problem under any ground conditions and handles iron great (I will dig iron on occasion looking for relics, but I know for sure if its iron or something else). I have manged several nice silver coins that had iron close by or in the same hole and new that there was iron there, but also silver. I hope this helps and if you do decide on a DFX send me an email and I will help you get through the learning process a little faster.
