US Patent 7975391 Archery sight leveling device

An archery sight leveling device for assessing the third axis of an archery sight of a bow system is provided. The bow system has at least one vertical reference. The archery sight leveling device comprises a main body with at least one rod receiving aperture formed through the main body. A sighting rod is receivable in the at least one rod receiving aperture with the sighting rod having a first end and a second end. A securing mechanism releasably secures the sighting rod in the at least one rod receiving aperture. A mounting mechanism mounts the main body to the bow system with the sighting rod being parallel to the bow string and the first end and the second end of the sighting rod extending beyond opposite sides of the archery sight. The first end and second end of the sighting rod are alignable to an external vertical frame of reference such that during full draw at an up or downward angle, the third axis of the archery sight aperture level is assessable thereby allowing offsetting of the bow system's dynamics at full draw versus the bow system at rest or static position.
