Abstract: The present invention provides a target illuminating and sighting apparatus for a bow. A frame for attachment to the bow supports two vertically spaced pivoting mounts, each of mounts supports a laser oriented to illuminate a target when the bow is aimed. Cams abut the pivotal mounts and allow for setting an angle of vertical convergence between the light beams so that the lasers intersect at ranges of between about 10 and 50 yards. An inclination cam, working synchronously with the convergence cam controls the inclination of the beams relative to the initial path of an arrow to be shot from the bow. The inclination cam may be calibrated to adjust for the particular bow and arrow combination.
