That' s why I still use my peep with the no-peep. I didn' t have to change my old way of shooting , and adjusted the no peep to fit my present draw. It will take two people to make the final micro-adjustments (one to move the no-peep while you are anchored comfortably) - but all those times when you THOUGHT you were anchored correctly, you really weren' t, and that' s why the shot was off. The no-peep will definitely let you know when you are off - even a little.
