This was White's top-of-the-line unit until they brought out the 3 frequency machines. (VX3, V3i) It's a terrific detector. The dual freq. correlate mode does a great job of iron cancellation when working around burned-down buildings where there are tons of nails, etc. It also does a good job on the beach when working back and forth from wet to dry areas. It can also be used in single freq. modes of either 3khz for silver, or 15khz for gold, platinum, nickels, etc, or you can run it in "best data" mode where it gives back the results from the freq. that gives the best returning signal. Good, used units are probably one of the best "bang for the bucks" out there right now. The downside is you won't learn to run it well in 5 minutes. Like all really good machines, it has a "learning curve". But, it comes with preset factory programs to get you off to a fast start...like coins, coin & jewelry, relics, and prospecting.
