Hardcores were designed to be the ultimate hook (single jaw) release with more features than any other. For starters, the HARDCORE has a self centering knuckle located behind the main body which eliminates side to side torque which is a major design flaw with other hook style releases. The body will actually pivot left or right for a total of 20° to compensate for varying anchor point positions. Once attached to a bow, the loop or serving will line up straight with the centerline of the release which allows for a perfect shot every time. The solid steel jaw automatically closes when you depress the trigger and when set with minimal travel, trigger pressure is a mere 4 oz We have added two great features to the new MAX. For starters, the MAX will have a separate screw that will adjust trigger pressure (separate from trigger travel) from 3 oz to well over 16 oz by just a couple turns of the screw. This feature will be useful when wearing gloves during late season you can now increase the pressure on the trigger for a solid feel. Target shooters can also now increase the trigger pressure for more of a back tension" feel. The MAX also has the new Evolution II buckle which has 2.5x more padding and is slightly wider with rolled edges creating the most comfortable strap on the market.
