I am trying to test my machine. I seem to find lots of clad, but no really old stuff. I have gone to places where I know there should have been old coins but I have had little to no luck. Thinking it was the operator, I tried a test in my back yard. I dug a 12 inch hold and placed a silver dime in it. My machine did not pick up the coin at all. Next I placed the coin a 8 inches and still did not get a hit. I was surprised. Next, I put a silver quarter in the hole with the same results. What gives here? Is the problem caused because the earch is not packed tightly around the coin? What I am trying to accomplish is to hear the different sounds of the deep coins. Any advise here would be of great benefit. Please advise.
