Traditional nocks cause a plucking of the string upon release which redirects the back of the arrow at the instant that it leaves the bow, greatly changing the arrow flight.

The tabs on the Accunock hold the arrow on the string, however during release the tabs are pushed open, and the tabs never make contact with the serving string.

Since the tabs never make contact with the string, and there is no longer a plucking upon release, there is also no friction between the string, and the nock. It's as if the nock has dropped away.

Accunock's innovative design accomplishes two things simultaneously. The first is that the nock is securely held to the string by the pinch of the tabs, and the second is that the tabs open on their own at the moment the arrow is fired. Without the need for modifications to the bow or the arrows. And the Accunock is as simple to use as average nocks.
