When you set the trigger sensitivity on the edge, look out, it’s quick! Our single jaw is steel and is also Teflon coated for a very smooth feeling bowhunting release. Because the jaw is steel, you can now use this release on an aluminum loop without any problems. We designed our moveable jaw to be positioned into the non-moveable jaw so there is never a gap for your loop to pass through. This release works great off of string loops, serving, or aluminum loops.
