I am OK if I close my left eye, its when I try to keep both eyes open I get a double image of the gun and target. Its as though I dont have a dominant eye, or maybe I'm left eye dominant (how does that work if you're right handed like me?)?? I guess I could just shoot with one eye closed, that should be OK for Turkey and static shots I guess, but I'm not sure how well it would work on fast moving targets? Anyone else have this problem?
