Before doing anything with the sight, Is your bow tuned properly, correct arrow spine and good fletching clearance?Check to make sure your arrow rest is in the correct position. Check your tiller. The arrow should be aligned with the rest mounting holes in your riser while sitting on the rest and knocked on the string. Also check the nocking point on the string make sure it is not too high or too low. Then check your "Center Shot" and paper tune if you can to get a descent hole, then sight in. Your sight should be in a better position for adjustments now.Sighting in on a bow that is not setup properly will often cause you to run out of adjustment when sighting in. Good Luck
