RE: Left eye dominant
Sounds like me. I'm right handed with everything I do and was (still am) left eye dominant. I started hunting a couple years ago and use all left handed equipment (guns and bows). It was different to me, but I got the hang of it now. The only downside I would say is in buying left handed guns/bows. My arsenal is located below on my signiture. All my guns are either lefty or ambidextrous. I would tell you to have him shoot however is most comfortable or maybe even teach him to do everything right handed. Good luck!
