Ok I'll say it once, for someone new, but that's it, no more not from me. If you wanna know the truth about MDing, no matter what detector you use. If you wanna go deep you have to search in all metal and dig it all. read up about masking for a start. Then also for those who don't know this little tidbit, no detector no matter how much you do or don't spend, is accurate at target ID beyond 4 inches. Therefore allot of older coppers and good finds etc... read as Iron beyond that. Although your detector might get lucky and guess right from time to time for the most part you gotta dig it all to be sure. 8)
