The revolutionary NO CAM ST™ Technology utilizes two circular and concentric string tracks, allowing the string to travel at a constant distance from the center of rotation during the shot cycle. This eliminates the common camming action on both top and bottom string tracks, creating a balanced and synchronized system with straight and level nock travel for superior accuracy. NO CAM ST™ Technology delivers a radically smooth draw cycle with incredible efficiency. This means that more energy is transferred into the arrow rather than being left in the bow to be experienced as post-shot sound and vibration This is a right hand Mathews HTX No Cam. it has less than 100 arrows through it and was my back up bow.
