The QuikTune Freedom is the only capture dropaway rest that does not need strings or cables to operate. Simply load your arrow from the top and you're ready to go. Innovative mechanism keeps the rest in the up position during a let down and always fires during a shot. The most accurate capture dropaway rest available. Works with all carbon arrows and aluminums up to 21/64th. Super precise micro adjustment for center shot makes setup and tuning a breeze. Lazer graduations on both vertical and center shot for easy setup. The QuikTune Freedom stays in the upright position during a let down, but shoots thru during a shot. Your arrow rides on whisper quiet friction rings that just won't wear out.
