I took the E-trac out to a 100 year old church nearby that I have worked about out. The last two times there I spent about 2 hrs per hunt. One hunt I came home with 2 lincoln pennies, the last hunt was a Buffalo nickel and a Canadian nickel. This yard is littered with modern aluminum trash and iron from all the years of occupation. Today I concentrated on a small area about 20 x 20 where I found some wheats way back when I first started hunting the place. I have never pulled a silver coin from this churchyard but was always convinced they had to be there. I have talked to the Deacon there that gave me permission to hunt and he said that there had been alot of fill dirt put on the lawn over the years since it's next to a creek and flooded back in the early 70's. So I reasoned that the silver was there it was just deep. I was right, the E-trac proved it. I dug 5 silvers and 10 wheats and $2.99 in clad. ALL of these targets were so masked by nails and bits of aluminum can that had been chopped up by a mower that I had to really work slow and have patience when pinpointing since the all metal pinpoint will grab onto the shallow or strongest signals first. Some holes would have 3 or 4 trash items in the same hole. I don't think I dug a coin under 6" today 8-10" seem to be the norm with the silver quarter at 11 maybe 12" and on a slant in the side of the hole. Check out the one wheat penny that actually had a nail welded to it in the dirt. I have hit this church yard with the Sov GT, The Original Sov, Idx Pro with Mr Bill's Mods, XL-Pro, Compass GSP, Nautillus IIb, Fisher 1266-x, Tesoro Vaquero and several others. Silver eluded all these machines but not the E-Trac
