Solution 2.5 Carter developed the original back tension release with a safety, the Solution, which holds several world and national records. The Solution 2.5 is a highly refined version of that release. More versatile than the original Solution, the Solution 2.5 allows you to begin your rotation from any point once the safety is disengaged. Because it is very short from fingers to hook, it does not shorten your draw length. The Solution 2.5 has a clean design and an internal hinge that is protected from your middle finger by the enclosed finger hole in the case. It also has the easiest and most refined adjustment of hook-to-moon engagement of any Carter release. Plus, it only requires one small movement of the set screw for adjustment and works perfectly on a D-loop or with a rope. The Solution 2.5 is available in 2-, 3-, and 4-finger models. It is a "must have" for serious archers. #CE133 2 Finger...........$129.99 #CE135 3 Finger............$129.99 #CE137 4 Finger............$129.99
