The Tru-Fire Synapse thumb release with true double-sear operation features a broad range of adjustments that allow it to be perfectly customized to any archer’s liking. Built on the platform of a weighted brass handle with an anodized aluminum cover, the Synapse allows users the 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 and flawless cocking of the trigger activation lever. The thumb button is multi-position configurable, with lockable adjustments for trigger travel and trigger tension. The trigger pressure is adjustable from a range of 1.25 to 20 ounces without the need to change springs or disassemble the release. The feature-packed Synapse handheld release is available in five color choices—red, blue, green, orange and silver.

    Tre-Fire Synapse

    I'm so glad Tri-Fire has provided such a high end thumb release. I'm very impressed with the solid feel and crisp trigger of the Synapse.

    Great release

    A couple years ago I transitioned to a thumb release. I just got tired of banging my wrist release on everything. Last season I upgraded to the Synapse. I love the adjustability.

    This release has all the bells and whistles. Several colors and great adjustability.It is a perfect match for users of the Sear and also want a thumb activated release.
