Great Merc congratulations. That was my first silver coin so I love all the Merc's. I gotta go with Boobydoo on the 6 hour thing. These last 3 weeks I did 3 days of 6+ hours of detecting. I did have a few finds, but I think finding the soreness of back and knees..and whatever all bones do the rest of the connecting to each end seemed to be the predominate finds each day.
