The Torque-Free Loop. The Pro Release Torque-Free Loop attaches to the bowstring to provide a convenient connection between the archer, release aid, arrow, and bowstring. Designed to eliminate bowstring torque for increased accuracy. The Torque-Free Loop combines the best features of a nock device, a string loop, and a rotating-head release aid. The Torque-Free Loop focuses the release aid directly behind the arrow, while allowing up to 90 degrees of rotation in either direction with a minimal effect on the shot or flight path of the arrow when extremely torqued.
