Now you can determine bullet-hole perfect center shot with laser precision. Ultra-fast and simple to
use for the novice or seasoned expert, all you have to do is attach Eze-Center to the bow's sight-mount
holes with the included thumb screws, turn it on and aim the laser dot towards bowstring. Adjust the
windage until the laser dot is centered on string then swivel and position the laser dot on the point end
of a nocked arrow. Adjust the rest windage until the laser dot is centered on arrow. Remove laser,
install sight and you're ready to shoot through paper. Can also be used to check cam and limb alignment. Unit requires three LR-44 batteries, not included.
