If you're looking for the state of the art release this year, look no further. The jaws on all of the Hurricanes open when you depress the trigger, and close when you let up on the trigger. The Hurricane line utilizes a free-floating, self centering steel roller that does not slide over the jaws but rolls along the inside of the jaws. This new patented design makes these releases the smoothest on the market today. The Hurricanes also have heat treated jaws and triggers that are Teflon coated for years of dependable use. All can be adjusted for trigger pressure. On a 70 pound bow, the Hurricanes take only 3.5 ounces of pressure to fire the trigger.
