This release is a resistance activated release and is perfect for taking proper shot execution. The release will fire when you increase the resistance. It is adjustable from 12-30 pounds depending which spring is installed. Four springs are included so you can achieve your optimum 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.
