The Evolution is a resistance activated release and is the perfect release for teaching proper shot execution. The release will fire when you increase the resistance. To fire the release hold the safety down as you pull back. Then once you get into your valley and anchor in, let your thumb off the safety and begin pulling and building pressure on the back wall of the cam until the release fires. This is a perfect concept for struggling archers; learning to do nothing but push and pull until the shot fires. Evolve into the best shooter you can be with the new Evolution. This is the exact same release as the Nock2it from John Dudley, except has the added benefit of the 3rd fingers which puts less tension on your hand! This is the perfect release to get better with each shot. Available now at Straight 6 Archery online!
