I had the module installed by a Darton dealer, so I,m assuming it was done correctly. Any way I think I figured out wat was going on. I had a riend shoot the bow, & on drawing the arrow was pulled off the rest. We put the arrow back but it was not touching the rest at all. We took the old string loop off, & some serving that was on the string & replaced a new loop. It seems to be shooting pretty good now. But thanks for the opinion any way.
