The " No Peep" requires you to line up a small circle inside of a larger circle. Once it is set up to match your own anchor point, head, eye, and arm alignment you will not be able to align the " No Peep" again without aligning all the other factors in the same way you did when you set it up. In other words, your form will be the same everytime you shoot if you line up the " No Peep" . In my own experience, this even includes any change in bow/hand torque as well. Once you get used to using the " No Peep" you will find yourself aligning it via your perifial vision and won' t even realize your using it. Needless to say, I' m sold on it.
