Been asking myself the same question lately.. The only thing I can come up with is letting you squeeze the extra 1/2 inch of draw out more easily.. I am also curious about this still.
My form and accuracy improved when I switched to a thumb release. Heck and that was with a "cheaper" one.
i think it helped my accuracy. it definitely helps with the surprise release and not punching the trigger. i also find it easier to draw my bow back with the thumb release. i use the spot hogg whipper snapper 3. i really like it, it has a née crisp trigger. sort of spending tho.
My accuracy and grouping improved as well. It takes some getting used to, but I think it is worth it.
I switched over to a TRU Ball Fang 3 and have noticed an improvement in accuracy, I don't seem to be anticpating the shot and punching the trigger like I did with the wrist release.
Ive only used thumb. I believe people out west use thumb release + hook for spot and stalk, not to be confused with another guy on this forum. The wrist release means something is dangling from your d loop while you stalk, not ideal. Hook + thumb release, you just have on your pocket, whip it out, lock it in and go. Thats kind of how a spot hogg rep explained it to me. Just uh, you know, don't forget to hold onto the release when you hit the trigger.
Stop trolling. I forgot how there is that piece that comes out to hook onto the D Loop. LOL. I forgot how the way you hunt is the only way others hunt. Wrong.
Not trolling.... trying to help a guy out and not confuse him with misinformation. A wrist strap release does just that, strap to your wrist, then attaches to string or d-loop via hook or caliper and utilizes a trigger which is activated with the pointer finger. Thumb release is hand held (although some do have a loose tether for the wrist) and the trigger is activated with the thumb (primarily) and attaches via hook or caliper. Wrist strap or "finger release" allows the bow to be drawn with the weight falling on the strap and wrist. Thumb trigger the bow weight is pulled by the hand holding the release. Your statement was inaccurate.... but I digress, and have zero interest in engaging you further. To the OP it is largely personal preference. I have shot both and like both under different circumstances.
You're right. I actually was wrong. I meant hanging from your wrist. I was too caught up in my anger to see that.
