ABSTRACT:
A laser sight with automatic angle compensation for bow hunting from tree platforms, comprising a box with open front and back ends attached to a bow handle. A laser pointer is pivotally mounted in the sight box. A cam operated by a pendulum moves the laser pointer to compensate the laser beam direction for different shot distances by detecting the vertical angle of the bow. The higher the bow is aimed, the lower the laser beam is aimed relative to the bow to compensate for the greater drop of the arrow over greater distance. A second pendulum in the sight box operates a peep pin for use with a conventional peep sight on the bowstring. The peep pin maintains an angle via its pendulum that guides the archer's line of sight to the laser spot, allowing the archer to visually acquire the spot quickly even during daylight. The laser beam and peep pin are coordinated via adjustments that are independent of each other and independent of cam or pendulums.
