I coach high school trap shooting and I have a student that is struggling he says he sees 3 barrels I’ve tried the basics but don’t seem to help anyone have any ideas
I agree. I had the same problem trying to shoot with both eyes open. One eye shooting cured the problem. Scores were always AA and sometimes AAA. Even when shooting trap with an 1897 Winchester pump. If he can't close one eye, then put scotch tape over one lens of his shooting glasses. You can place the tape in the right spot to be able to see the bird launch but still block out the eye when shooting. A video available called Trap Shooting for the One Eye Shooter.Central vision, no dominate eye? May need to shoot with only one eye.
I understand that, I should have been more clear. I meant to ensure there is nothing seriously wrong. My suggestion about using a brock string is still valid though. It is a very common technique to train your eyes to converge amongst other things. It isn't only used for situations like mine. It is nearly free and can help shooters who have dominant eye issues.My suggestion was "best case scenario", a fairly common issue. Worse case, possible serious health issues that need immediate medical attention.
It can work miracles. After my brain injury, I saw doubles and triples of everything whether I was trying to shoot or not. After a few months of using the brock string multiple times a day (I would carry it in my pocket and pull it out any time I had a few minutes), the vision issues went away. I haven't used it for shooting specifically but, knowing what it does, I suspect it will work well for that too.cavedweller, Brock string exercise videos(idoc2008) has a good video on YouTube. Demonstrates and explains what/why the exercise is needed. I'm going to try it, see if helps with open sight shooting.
