The Chocolate Lite Thumb Release by Carter Enterprises delivers unmatched adjustability. It comes equipped with the innovative Interchangeable Tension System (ITS), which allows archers to quickly change from one trigger spring tension to another by putting thumb pressure on the small black box near the thumb trigger and carefully removing the case screw using a 1/16 hex key and remove the box. After that fit the desired spring into place, replace box, and hold it with your thumb while replacing case screw. Trigger travel can also be finely tuned to the user’s preference via set screw – turning the screw clockwise decreases travel, while counterclockwise increases travel. In addition, the Chocolate Lite utilizes auto-closing jaws, making it perfect for hunters. Available in 3 finger and 4 finger configurations.
