As I shoot my (I shoot with both eye open) dominate eye changes from rignt to left. I have tried to close the left eye, and tape on the left lens, but both really screw up my shooting and scores. I have tried the sight blinder and that didn't seem to do any good. I went to the "Easy Hit" site, and wasn't able to get into the FAQ area. Aside from that the over-fifty-dollar price puts me off. Contacted Aveage Ed, and he suggested the tape on the lens which having tried dosn't work for me. What to do?
