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.

    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.

    Synapse release

    Posted by Craig on Jun 9th 2022

    I recently got into the market in search of a new t handle release to upgrade from a older 4 finger to a three finger. I shot a bunch of releases in all prices ranges before deciding on the synapse. I have been shooting this release for a few weeks and honestly think it's best in class. I have recommended this release and let other try it and three of them ended up ordering one. If had to split hairs and offer something negative, my only very small complaint would be having to manually lock the jaw after setting the trigger. This really doesn't bother me but it would be the only change I would make to perfect this release. If you are in the market for a thumb releas give this one a look, you won't regret it.

    Great release. Adjustments are great to suit your preferences. Little to no creep in the system. I only wish I was able to get the orange.

    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.
