TruFire Synapse Thumb Release

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 four color choices—red, green, and silver.

My first thumb button coming from the regular wrist strap trigger and this release has made quite the difference. Easily change sensitivity and button travel. Nice clean break and I love how it feels when I pull back from what I was used to. I highly recommend!

The synapse release is the best release I have used. It out performs a wrist release easily. Quality product and won't use any other release again unless Tru-Fire can produce a release that is better than the synapse.

Good release. Crisp break on the shot. Good weight and ergonomics. Don’t like that the thumb barrel easily unscrews and set screws have too much paint in the and it’s nearly impossible to get an Allen wrench in the screw head.
