I listened to 3 successfully dug coin targets today. I detected them in combined in auto sensivity. Switched to conductive mode. My conductive mode was set with everything disc in but 24-35 ferrous 37 -50 cond disc out. All 3 targets were not near as good sounding in conductive vs combine. One was a merc dime at 4 inches with nail. The others were a buffalo nickel and real deep 10 inch old wheat. The merc dime was actually duller sounding with a slight broken tone. In combine mode the merc was singing like a canary coming in at 12-40 consistently with a 2 way hit. By the way this particular spot was killed by etrac and v3i by me personally.
