The Impetus Fast Hook has an open hook design for quick and easy loop hook-up and match grade trigger crispness for your bow. The trigger tension on this release is fully adjustable and the hook automatically closes after each shot. The release is attached to a flexible leather wrist strap by a micro adjustable post that will never slip. The release wrist strap end closes into a buckle--like a belt buckle. This ensures you get the same strap diameter every time. If you have never experienced the pure simplicity of a hook style release then the Impetus is a great release to see for yourself why everyone is making the switch!
