ABSTRACT:
A distance indicating mechanism can be used in combination with a bow sight to quickly determine distances to targets from an elevated position. The distance indicating mechanism has a generally circular, fluid-filled tubular device with one or more adjustable indicators located thereon. The indicators are positionable to correspond with the fluid level in the tubular device to indicate the orientation of the mechanism when aiming at a known distance. Each indicator generally corresponds to a sight pin of a bow site that indicates a corresponding linear distance for which an arrow will be at a desired vertical position when shot by a bow operator.
