To find the centerline sit down and rest the bottom cam of the bow on your leg, then sight the bowstring through the center of the upper wheel and follow that line down to the grip.

What you will probably notice is that the grip itself is not centered, but offset to the right.

Most of the time the sight pins will be oriented to the centerline, but the rest itself will tend to be about 1/8" to the left of the centerline for the bow to shoot its narrowest groups.

Good luck hunting! >>>------------>
