I would take the time to explain it, but there are others that are so much more experienced at it. Try the search feature here, or definitely go over to archerytalk.com and try a search there. I know there were some very good explanations over there. If you are talking about a Bowtech dually, then I would start by making sure both cams are hitting the stops at the same time. Try shooting hard off the wall, and creeping forward a bit. You really can't creep too much with the duallys, since the valley is very short.
