I used to shoot both eyes closed, but that didnt work out so good. Seriously, I'm left eye dominant and shoot right handed. I'd like to shoot both eyes open but I just cant do it. I showed the guys at the range what happens when I use two eyes, not only did I miss the target but I sent an arrow sailing into the woods. I can train my eye to shoot both open, but if I'm not concentrating, its a big miss. I'd hate to have that happen when hunting.
