ABSTRACT:
An archery rangefinder sight comprises a housing affixed onto the bow, with a power supply and a rotary mechanical or magnetic switch that has a shaft protruding through a side wall of the housing. A bowsight element employs a number of sight pins vertically spaced above one another and mounted either on the case or as a separate element attached to the bow. A number of LED's or lamps are mounted on the housing so as to be visible to the archer when aiming the bow. A weighted pendulum arm is adjustably mounted on the switch rotary shaft to rotate the same as the bow inclination changes. Then one of the lamps becomes illuminated to indicate the range to target, and the bow is aimed and shot according to a respective one of the sight pins.
