The Edge has worked out well so far, for myself. I was able to get out and hunt for a few hours with it this winter. My opinion is that it is a very fun machine to use, first and foremost. I had a great first outing with it, in which I found my first silver coin.
The number ID sometimes has trouble "locking on." The silver coin that I found came in at one point at a +21. After swinging from a different direction it then went into the +30's. Either way I would have dug this signal though....Also, I did get some +36's, which turned out to be negative numbers (-) after a switch in swing direction. Digging these targets, they usually turned up as a long piece of wire, or a hunk of junk metal. Between the tones and numbers, I think it is hard to go wrong with the Edge.
The Pinpoint is great, and I was digging accurately. You have two guidelines - the sound increase and the numbers, a great combo in my opinion.
Maybe it's due to the fact that I came from a basic machine, but I have really taken a liking to the Edge. It's flexible, but take your time, and check your targets from different directions.
Good Hunting,
