It was 37 degrees this morning and the wind was blowing 12-15mph so I bundled up to squeeze in two hours of detecting. I only found four coins, but two were silver dimes. The first one has a little drama to it. I got a perfect repeating silver warble that showed somewhat deep on the gauge. When I squatted to dig, I noticed a healed over plug was just about where I pinpointed. When I dug, I found a piece of rusty wire at six inches. I knew this was not the signal I heard so I enlarged the hole at the bottom and found the target two inches deeper, but two inches off to the side. It was a 1933 merc. Someone was real close to that one. Second silver was a roosie from 8-9 inches deep from a spot I have been over many times. It was a perfect signal. This just proves that if you are off 2 or 3 inches, you might as well be off ten feet.
