Hello again everybody, just got back from Vegas and Oscoda so I've been away for a few weeks. Glad to be back and out hunting again. So the official count of coins I've found is 159 and I've only found 4 wheats and no silver. Am I doing something wrong? I know my machine isn't the top of the line, however, it's a good machine. ( or so I feel) Does anyone else have this struggle?
