Abstract:
1. A bow-mounted sight unit containing a range finder, with data storage, the sight unit comprising: an optical sight unit for viewing a target area, the sight unit having a housing member supporting a viewing screen member and at least one optical lens member that comprises a field of view when viewed on the screen member; a cross-hairs member having a vertical sighting cross-hair portion perpendicular to a horizontal sighting cross-hair portion for identifying an intended target, the cross-hairs member spanning the interior of the sight unit and superimposed on the viewing screen member; a vertical cross-hair portion adjustment member to allow for fine-tuning the positioning of the vertical sighting cross-hair portion; a laser range finder member mounted in the housing member, the range finder member calculating the range distance between the optical sight unit and an intended target; a microprocessor member mounted in the housing member; a data storage member operatively connected to the microprocessor member; a control member for manually entering and accessing data retained by the microprocessor member and the operatively connected data storage member; a display member for displaying the data, the display member included within the viewing screen member and visible in an area adjacent to the field of view; and a power source mounted within the housing member for energizing the viewing screen member, the range finder member, the microprocessor member and the data storage member; wherein the microprocessor member calculates an arrow drop compensation distance automatically using historical arrow-drop data in conjunction with the range distance, the compensation distance displayed in the field of view by automatic adjustment of the cross-hairs member by the microprocessor member.
