Rick, Most center shot gauges, lasers and what not will show you center shot on a relaxed bow. That's not going to do much for true center shot. As reference yes, as true center shot, no way. When you come to full draw so many things change from the relaxed position. Limb flex, cam angle even some riser torque. Get two fletched, STRAIGHT arrows and 1 bare shaft. Shoot the two fletched and then the bare shaft at a target about 15 to 20 feet. Adjust your rest until the bare shaft impacts just below the fletched arrow. You have true center shot.
