NOTE: Truball Flex releases no longer come with the additional 4 finger adapters 

The new Abyss Flex is a brass thumb activated release, that use the same exact handle as the Fulkrum and Fulkrum Flex, with the same impact points. The Abyss Flex also uses the same Lever Alignment System (LAS) Technology as the Fulkrum and Fulkrum Flex. What does this mean? It means that you don't have to worry about what hinge/backtension release to choose, you now have one to match in the Fulkrum or Fulkrum Flex. The Abyss Flex has a single sensitivity adjustment screw with a lock that can be adjusted infinitely for your personal feel. Re-tighten the lock after your adjustments are made. New in the Abyss Flex is the comfort flex technology that now allows the archer to select infinite finger locations on both the three finger and four finger handle pieces. Each piece can be individually moved a total of 30 degrees. The Abyss Flex feature a simple locking travel adjustment screw, that allow you to set the travel to your preference quickly and easily. An adjustable thumb trigger comes standard on the Abyss Flex allowing a "where you want to feel." All Abyss Flex models contain the pieces to make your release a three finger or a four finger release. Crisp, clean and comfortable shots are what you can expect with the Abyss Flex.
