White's TreasurePro

The TreasurePro was the step up from the TreasureMaster, adding manual ground balance and finer control while keeping the same easy starting point. The 10 inch waterproof DD coil that came with it is a good general-purpose size, and the machine had a reputation for stable running in the kind of mineralized ground that makes cheaper detectors chatter. A sensible second detector, and a lot of them are still in regular use.
