I guess I was looking more for experience with non-VDI machines, that weren't Tesoro. Not that I have anything against Tesoro, in fact, it's just the opposite. With all the chatter about waiting for a new machine, and people hoping it's going to be like all the other top end machines, it's got me thinking that Tesoro provides detectors that no one else is making. A non-metered machine that can be used amongst the can slaw, pull tabs and nails that I find everywhere I hunt. Does anyone else make one? DeepTech seems close, but the disc seems pretty minimal. Has anyone used a DeepTech at a local park full of bottlecaps and pulltabs? If so, how was it?
