  • Patent number: 5305530
    Abstract: A bow sight for use in archery hunting provides for the automated compensation of target distance and elevation differential factors when bow hunting from a relatively elevated site, such as a tree stand. The sight is formed in a generally L shaped configuration, with a pivot at the juncture of the two legs. The forward leg includes a plurality of sight pin mounting points, into which a close distance sight pin and a far distance sight pin may be installed. The sight is mounted to a bow, and the pivot provides for the sight and pins to maintain a constant position relative to the horizontal. An adjustable balance weight is provided in the rear leg of the device for fine adjustment. As the bow is raised or lowered to adjust for different target distances, one of the two sight pins will always appear to be lower than the other, or in a singular situation will be aligned with one another.
