An open design release like Short and Sweet made by Tru Ball Will greatly help with this problem.I have never had a problem with calipers but when I shot them,I shot thousands of arrows a week and it was second nature to me.
It just slides in from the side and doesn't need to be opened to get it on.
I have hooked mine up while looking behind me at turkeys.
