Hereis how I tune my bow. I first get my center shot and nocking point adjusted close by eye. I then sightin my bow for field points out to 50 yards. Then I take a field point tipped arrow and a broadhead tipped arrow and start at 5 yards. I shoot the field point arrow, and then I shoot the broadhead arrow at the same spot. I adjust the rest for left or right to bring the broadhead tipped arrow with the field point tipped. I do the same for height, except I move the nocking point. I do this out to 50 yards or so. When you get to 20 or 30 yards, you may need to readjust your sight to bring both arrows into the spot.
