I've had mine for almost a year now, and have no complaints. It's *excellent* in parks and tot lots - the pinpoint mode means I can often find targets near metal equipment if I go slow and listen carefully.
I've tried it on the beach too, and my biggest issue is that the 8" coil it came with really isn't big enough for that use. Yes, wet sand makes it false, but you quickly learn how to "tune out" the worst of it and find targets. The last time I was on Sandbridge Beach (Southern Virginia Beach), I found a dozen or so .308 bullets in the wet sand. They rang up nice and clear, even at six inches deep or more.
