Well, maybe it's tougher than it seems to be... If it can hang with you in the woods and you don't have problems with the shaft wobbling or the batteries not making connection, then I'd say it passes muster. Since it came out I have been back and forth on whether or not I want to buy one. Sometimes I really want to buy one, then I read through a batch of reviews where folks have had to send theirs back over and over, make their own modifications to hold batteries in, keep the shaft from wobbling, and reduce EMI, and then I don't want one again. I am back at maybe.
For the deepest coin shooter, my opinion is still that a CZ7, 7a, or 70 is going to be really hard to beat. CZ depth is still legendary. That's why you don't find them for sale often. I haven't personally compared it to many other machines though, only a few other detectors like the ace 250, and a Whites DFX. Neither could perform as well. The DFX was one I thought I really wanted when it first came out too.
