Abstract
A laser based range finder which may be inexpensively produced yet provides highly accurate precision range measurements has a number of user selectable target acquisition and enhanced precision measurement modes which may viewed on an in-sight display during aiming and operation of the instrument. Extremely efficient self-calibrating precision timing and automatic noise threshold circuits incorporated in the design provide a compact, low-cost, highly accurate and reliable ranging instrument for a multitude of uses and is adaptable for both recreational and laser based "tape measure" applications.
