The Synapse is built on a weighted brass handle with an anodized aluminum cover, thumb button and the archer’s choice of two finger extensions—a hook that wraps the ring finger for a 3-finger configuration as well as a fourth-finger extension. The internal stainless steel components are precision milled for exceptionally crisp operation. Pressing the Synapse’s cocking lever activates the trigger. The thumb button is multi-position configurable, and there are adjustments for both trigger travel and trigger pressure. The trigger pressure is adjustable from a range of 1.25 to 20 ounces without the need to change springs or disassemble the release.
