Does anyone have a cheat sheet made for the Etrac as far as FE & CO numbers for normal coins and gold? For example is there standard numbers for U.S. coins that will almost always hit the certain numbers? I don't have a full set of coins to test to see what they may be. I did dig quite a few clad today and they were all in the 12-36 to 12-46 range. Any help is appreciated.
