The SCAT model JS is a caliper style release with a velcro wrist strap.The JS is an automatic release that can be set with a delayed firing time of 0 to 6+ seconds. You adjust the timing to what you want. I like 1 to 2 seconds my son likes 5 to 6 seconds. This way you can just aim and not have to think about the trigger. The JS can be used with the release string, a D-loop or right on the bow string. I prefer a D-loop. To operate the JS you push on the back of the jaw to open it, place on the string let the jaw close and pull down on the trigger, and hold the trigger down. Now draw your bow, aim and move your finger forward off the trigger. The hydraulics will push the trigger forward and fire the release. If you want to stop just put your finger back on the trigger and pull down. Because the SCAT works with hydraulics and O-rings the timing will change with the temperature, faster when warm, slower when cold. That is why the speed adjustment is so easy to make. There are two ways to adjust the speed . The trigger adjuster screws in and out to adjust travel. This can be done with your fingers. The needle valve can be screwed in and out to adjust flow rate. This can be done with your thumb nail or a dime. The JS is made of anodized aluminum and stainless steel, no rusting. The JS is about the same size as other caliper releases. The jaws are hand polished and very easy on servings. For me shooting the JS is much like shooting a back tention release only I have more control and it is a caliper instead of a hand held .
The JS is available in black and comes with a velcro wrist strap.
