ABSTRACT:
A bow-mounted sight unit, containing a range finder with data storage, includes an optical sight unit for viewing a target. The sight unit has a housing which supports a viewing screen. A cross-hairs member has vertical and horizontal sighting cross-hair portions and is superimposed on the viewing screen. A laser range finder member calculates the range distance to the intended target. A control member allows entering and accessing data retained by a microprocessor member and connected data storage member of the unit. Data is displayed on the viewing screen adjacent to the field of view. In operation, the microprocessor member calculates an arrow drop compensation distance automatically, using the historical arrow-drop data in conjunction with the range distance. The compensation distance is displayed in the field of view by automatic adjustment of the cross-hairs member by the microprocessor member.
