I agree with Big Papa , I have a laser tuner ans I use it but you still need to shoot throught paper to make the FINE adjustments .

laser tuning is a device that bolts to the bow where the sight mounts
to get the center shot.
you set the beam to the center of the string then place an arrow into the rest and set the arrow to the center of the laser beam for perfect center shot. Clear as Mud?
