Resistance style releases are fairly new to the market and they operate by setting the release weight to your holding weight plus some differential. Once at full draw, activate the release, then add that differential weight and the release will fire.
It’s a simpler way to shoot using backtension because there is no rotation involved, just squeeze with your back and it will fire. But resistance style release aids are the most difficult to design AND manufacture; succeeding here is what sets a premium manufacturer apart from the pack.
The NEW ElementTL is the second release in STAN’s® lineup to use the Smokin’ XTM sears. Whether your shooting a light draw weight for indoors or a heavy 3D setup, the ElementTL offers extreme repeatability with the reliability and consistency you can only find in a STAN®.

Like anything worth having, STAN’s® Smokin’XTM sears were a long time coming. Theory alone will not result in a design that is repeatable. Only painstaking craftsmanship and revision after revision will get you there and with the Smokin’ XTM sears they took their time.
