Dnk The C-10 is not designes to be hooked to a loop. Although it can be hooked to a loop it is very cumbersom and very slow to do so. The problem is that once fired or in the "disconnect" position the little hook that flips up into the release gets blocked by the trigger mechanism. You must reach around with your finger and manually close the hook around the loop.

What it was actually designed to do is snap closed when you push it against the bow string.

Winn Archery has two models that are specifically designed to connect to a loop. The "loop hook" and the "SS Caliper".
