A bow mountable range finder for elevated tree stand use includes a housing and a triangular tubular chamber containing air and medium viscosity liquid. The triangular chamber contains a horizontal venting section, a vertical indicating section, an inclined section and a horizontal reservoir with air and liquid freely movable throughout chamber depending upon the orientation of the range finder. The indicating section is translucent and has a removable graduated scale calibrated for various heights above ground, a battery powered lamp illuminates through the indicating section and scale. A switch is operable by an archer outwardly of the housing. The reservoir section is sized to accommodate approximately one-half the fluid capacity of the indicating section when the range finder is horizontal and thus allows for rapid lowering of the liquid level when the range finder is rotated counterclockwise. The venting section is sized small enough to impede liquid flow beyond the half full level of the indicating section.
