Okay, here's what I'm trying to figure out. The multifrequency operation of the V3 (and BBS/FBS, CZ's) is supposed to enable better depth in bad ground.. am I right? Now, has anyone compared a decent PI (TDI, Minelab, Infinium) with the same sized DD coils to a V3, and what kind of difference was there? I'm talking actual measured in-ground targets and the same targets for each detector. I don't care about ID, just raw depth. I hear a lot of anecdotal 'evidence', but not much hard data. I posted on Carl's forum, but it doesn't seem like anyone there has much to say. Figured I'd try here. Right now I have a V3 and am debating whether I should keep it or trade for a TDI. I plan, when the weather gets better, to do some nugget hunting over really tough ground. Now, I don't mind if the V3 get's, let's say, 80-90% of the depth of a PI in bad ground because there are other factors in it's favor (better small gold sensitivity and disc. options is one), but any more and I'd have to make some hard decisions. Anyone? ..Willy.
