The Carter Only release features an angle that can be adjusted up to 35 degrees. The 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. Carter has replaced the 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.
