Discover the most significant improvement in hinge release technology in 50 years. The ONLY is simply the smoothest and fastest hinge release in the world. But it gets better. The angle can be adjusted up to 35 degrees, and with the revolutionary Variable Crescent Technology (V.C.T.), firing speed adjustments are limitless. Traditional hinge release firing speed is controlled by the hinge position on the half-moon. Weâ€™ve replaced that half-moon with your choice of three crescent cams that range from 0 to 5 degree of radius curvature. The magic is in the cams giving you total customizing of the release head angle and firing speed. The ONLY is self-loading by means of a magnetic-head-return and designed to be shot from a D-loop. Available in large or small sizes. The ONLY provides endless adjustment options and is destined to be the ONLY hinge style release you will ever need.
