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.

    Minor inconveniences but great overall

    very clean crisp release, Love the extra weight from the brass and steel. My only complaint/issue that you have to manually open the jaw before priming the sear, I would like there to be a small spring to keep it open till you would manually close it.

    Release performance

    This is by far the best release ive ever used. The dual sear is smooth and the reset is very crisp and secure. I would definitely recommend this to someone wanting to get into hand held releases

    ive tried out thumb releases in the past and have not been very comfortable with them. This one is awesome. Very adjustable and great to shoot.

    Smooth, quiet, and weighted just the way I like it. It's a great release for 3 or 4 finger

    Synapse release

    Posted by Phil Madonna on Nov 30th 2021

    After shooting a index finger release for many years, I made the switch to a thumb release. My groups immediately got tighter and my confidence grew. It is totally adjustable and customizable. Several colors to choose from. I went with red. Very pleased with the quality and performance.

    Excellent thumb release

    Posted by Stephen Robinson on Nov 30th 2021

    I've used several brands of thumb releases in the past, but have really come to love my Synapse. They thought of just about everything with this release. Extremely adjustable and comfortable in the hand. I self film, so having my release clipped onto my D-Loop just takes one extra step out of the equation and allows me to get on target quicker when it counts.

    Synapse Review

    Posted by Stephen Robinson on Jan 13th 2020

    I've been shooting this release for about a year now. It's fantastic. Well designed. You can adjust the tension and the travel of the release independently which really helps you dial in the exact feel that you want. It has worked flawlessly for me.

    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

    Posted by Stephen Robinson on Aug 15th 2019

    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.
