[QUOTE="dwt, post: 92742, member: 428"] I have seen some gold and junk, been dug up deeper than i would of thought/assumed the coils could penetrate, eg: a 6" old aluminium pot faintly picked up (after it was dug) on the measuring tape at 1250mm with a gpx 4000 and eliptical mono, from memory about a 14x10 14x12, once it was removed from the ground a air test was done at the same height and zip, nothing at all, go figure 8) [/QUOTE]
