I bet this question gets asked way too much,

I have a Jaguar and am starting to shoot again,,, 3D, but for now just getting going in the back yard on the target.

My question is. Do I need to change the entire cam for draw length adjustments?? It has been some time since I have been shooting and do not remember the cam types, and adjustment procedure.

The cams are marked Zhl and the black cam insert ( 2 piece cams ) is marked 7x the bow is a 55-70 let off is HL with a 57" string and marked 29" draw. I have added a string loop for the release and want to get back my comfortable rear anchor point,

Thanks Doug
