RE: which is blurry, deer or pin?
Confirming what others have said about marksmanship training, you are always taught to focus on your sight pin. That said, when I took up bowhunting I read everything I could and it seemed like all the bow guys cut opposite this rule. So, I started letting the pin blur and focused on the target. However, this year, I am returning to the sight pin focus technique, and am finding it to be a great cure for target panic.
