I'll admit I don't know what I'm doing with this detector but I'm willing to learn and try different settings. I put it in Park 1,1 with a neg 3 GB,9 iron bias and 15 megahertz. In a yard that has been hit hard by every other brand of detector,I found 47 cents in clad 1 quarter,1 dime,one nickel,7 stinkin lincs, one 1950 Roosevelt dime and 3 wheat pennies,1941,1950,1954. I kinda cherry picked the 20+ vdis and the high tones. I passed up alot of solid signals in the 15-19 range after I had dug about 15 nails.My best day yet and I anxious to try more settings.Anyone get anything godd in the 15-18 vdi range?
