I have been detecting an old house and have found at least 20 or so wheats and a 1961 silver quarter and a 1953 silver dime the past few days. I ran into my problem when I first started detecting. My detector went nuts. I tried making all the proper adjustments and nothing seemed to work. Finally, I looked at the screen and saw that -10 through +8 kept popping up over and over so I just discriminated them out. That let it run somewhat stable but it was still acting funny. Come to find out that this yard has quite a bit of iron in the ground and this yard has a electric dog fence in the ground! So does both neighbors! Yesterday I was playing with my detector and found that if I put the filters on 12, it calms it down alot! I usually run 5 where I am at but I put it in 10 for this place on the start. Then I changed to 12 and it did seem to quiet it down. Still cant use analyze on anything! When you try to analyze, It just flat lines and says -10 at 0". This is a tough spot to detect but I am going to keep playing with it!
