I started out with the old Garrett detectors,and when they wouldn't do as advertised , I switched to Minelab, waaaayyy back in time. and I stayed with them, had many of their detectors,, But I think they haven't done right by touting the XT 705 as a prospecting tool. I've tried it in WASH. state and North. CA.and couldn't do anything for the hot rocks. I had the old 16000 , and it could null ll them out. Anyway, I just had to say it, I don't think they've done right by the buyers this time.. I know I'll get a lot of flack about this, but it goes with the territory.............and every one is entitled to an opinion............
