ABSTRACT:
A bow sight for determining proper range includes an energy source and a series of mercury tilt switches, each of which becomes operable at a different predetermined angle of bow inclination. A series of light emitting sight pins are connected to the tilt switches via an electronic circuitry that allows for the energization of a different sight pin for a different angle of bow inclination.
