The best one to use, is the one you fully understand. What ever you have just get out and use it enough. In time you will find items, you'll be proud to show off. i have two detectors, both by different companys. I love the higher price one, but my best find was with the cheaper one. I believe results come from three areas: 1 detector, 2 operator, 3 where you hunt. If it ain't there you wouldn't find it.
