I’ve been a long time user and fan of your detectors , I’ve owned the 6000 di pro plus , XLT , prism V , TDI sl and the DFX . All of these machines shared some great common qualities , they were all well built and their performance was top notch . The DFX has been my go to machine for the last 12 years now and it has seen 1000’s of hours of use in all types of weather and conditions . The types of coins and relics i have recovered with this machine is a testament to its great capabilities and the good people at Whites who design , assemble and test them. After all those years I finally had to send “her” in for a tune up and the turn around was remarkably quick and the machine function just like new again ! One of the first finds once I had it back was this 1787 Machin Mills counterfeit King George III copper found at a site that many I personally know had been to just weeks before .
