From all the reports I've read on the Minelabs, I wonder if you're likely to find any machine, regardless of brand, that is consistently deeper on coins, if compared coil size for coil size, in the same ground with a knowledgeable operator on each. If you typically hunt parks, fair grounds etc. for older, deeper coins, it's very likely the 10X12 coil will be picking up more trash than you'd care for, making separation of good and junk targets very frustrating. The subject of coin depth can be quite frustrating as well, due to the number of inaccurate or poor guestimates of depth that get thrown around. If you can make contact with a dealer or two or other hunters with different machines to try out, you'll probably get a better idea of actual depth in your ground than well intended but optimistic opinions on the forums. My two bits.
