  • Bow sight
    Patent number: 4368581
    Abstract: A sight for hunting bows possesses an automatic range finding capability when the hunter is stationed at an elevated position and is infinitely adjustable and lockable to facilitate ground level hunting. A greater range of adjustability enables the sight to function properly on various sizes of bows and with various arrow shaft lengths and weights rather than with only a single bow and arrow combination. Greater simplicity of construction of the bow sight is also achieved.
