I had one for years but finally sold it and bought a Quattro. It was a GREAT machine but is a dedicated gold detector. All the comments above are true. It will find the smallest bit of gold WAAAYY down, but it will also find the smallest bit of screen wire, aluminum, tacks, etc. In trashy places it will drive you NUTS, but out in the wilds away from civilization it is a gem! Be prepared to dig every bit of birdshot anyone ever fired out in the hinterland. I once was way out in the desert miles from anywhere, got a signal, dug down about eight inches and found a piece of screen wire about 1/3 inch long. Another time I got a rather weak signal, dug a fairly deep hole constantly checking my nugget scoop. Finally got it in my scoop but couldn't find the darn thing. It turned out to be just about the smallest piece of gold that could be legitimately called a nugget. Point is, you have to dig all signals with this machine, so forget the parks. It's just way too sensitive. But if you're hunting raw gold, it's about the best VLF out there.
