All right, basically when you have a mechanical release being used with a hunting bow, or any compound bow for that manner, a caliper release is the best type to use. Caliper release means that it opens both sides at the same time. Can you see it? Now, when you have a caliper release, you can then put a loop on the string. The loop actually makes it easier for you to hook the release up. And when you pull back, the loop around the arrow creates a situation where, as you pull back, the string perpendicular to the arrow. It doesn't actually angle as you pull back. Which would happen with a T-release, but I'll show you that in a minute. What I want you to do is put an arrow on here Vicki, and then put the caliper on the loop. Now, if you focus in on where the arrow is making contact to the strong. Hook it up. As she pulls back you'll notice that the arrow stays perpendicular to the string. So that when you release the string, the arrow gets pushed out by a perpendicular string rather than an angled string. Now, with a T-release, I'll take another arrow. The T-release gets hooked on under the arrow. It doesn't get hooked on to the loop. So, when you come up, and turn your hand, you notice that there's an angle where the arrow actually hooks on to the string. And when she releases it, that angle has to first click forward and then push out. Of course, it's faster than the eye can see. So, when you're setting up a bow with a T-release, you always want to have some kind of a support under so it doesn't jam up against the knock of the arrow. When you're setting up with a caliper release, you always want to use a loop around the string.
