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.
