If your left eye dominant and you shoot right handed , if your dominancy is as bad as mine , you'll need a good 10" sight extension bar to bring the sight out to the left (on a right handed bow) , if you can see through the peep to begin with
Impossible to shoot a compound right handed using a peep and sights with a left eye dominance and using that left eye
Repeat - impossible
Left eye dominant shooters shoot right handed and use their right eyes - their NON dominant eye. Now, when you draw the compound and anchor, that peep is right there for you to use with your right eye.
USE IT
Concentrate, and there will be no problems at all. Lapse your concentration, and BLAM! you're looking with your LEFT eye, on the outside of the peep and you cannot shoot JACK that way.
Again, I need only to point out that for every waking minute of the Right Handed, Left Eye dominant persons life they have COMPENSATED and LEARNED to do things the very same way. You change it for shooting a bow, then it stands to reason you also change the way you eat, hold your omputer mouse, write a letter, throw a ball, golf .......... ahhhhhhhhh, you see what I mean, don't you ? Because you're NEVER going to change all those things that you likely do well anyway. Right ?
Archery is no different. I'm VERY left eye dominant, I DO know what I'm talking about here
