  • Patent number: 5347722
    Abstract: An archery bowsight, for use in a tree stand, or otherwise, to be fitted onto a compound bow, or other type bow, having a rotatable pendulum affixed inside a mounting framework, and the pendulum controlling the location of a free moving pin sight inside the framework, and therefore, in the path of the flight of the arrow, for instant and easy fixing on the target. A biasing counterweight arrangement on the pendulum corrects for different target distances, and an adjusting plate, affixed to the one side of the mounting framework, controls the fine tuned location of the pin sight, for high, or low misses, while bore sighting the archery bowsight. The archery bowsight also has a locating nut arrangement on the stem of the mounting screws to control the sideward location of the archery bowsight, to correct for side misses while bore sighting the archery bowsight.
