Targeting system
A targeting system operable to be used with a bow to assist an operator with striking a target with an arrow. The targeting system comprising a processor, a target sighting window, a ranging module and a projector. The processor is operable to determine a range (distance) to the target and determine an orientation of the bow to strike the target.
