Just wondering if you have ever tried Coin shooting in 4/4h tones with 0 discrimination. I am heading out this evening to hit a Golf Course where I am finding Civil war and 1920-50 era coins. Gonna see if I can find some targets that I might have missed. Dankowski says that it acts much like the Cz-3d when detecting old coins in this mode. Never used one, but hear that they were killer on old coins. Anyone have some input? May have used the Cz-3d and found some old coins let me know I am interested. I just hope I don't encounter to much interference from power lines.
