The Echo release features Scotts HyperJaw design. Scott engineers spent hundreds of hours to develop and test dozens of geometry configurations. The result is a never seen configuration in archery releases. The independent jaws operate in great synchronization with one another. This removes any lateral torque that may come from inconsistencies in shooting form. The asymmetrical design delivers unmatched efficiency in the jaw opening response. The Roller Trigger System (RTS) provides a silky-smooth trigger action.
