Abstract: The present invention relates to an optical measuring devices and method of using the device. The optical measuring device utilizes a plurality of lasers attached to a plurality of interconnected legs to optically determine CENTER, LEVEL, LENGTH, DISTANCE, and PLUMB related to a measured object. In an exemplary embodiment, a user can sight reference laser beams at a first and second point on an object. A mechanical interrelationship between the interconnected legs of the device orientates a laser beam emitted from the center laser at a point, which is equidistance between the reference laser beams. The optical measuring device can include a level, a distance finding attachment, and or an electronic system 500. Electronic system 500 functionality can include, but is not limited to, data processing, data communications, GPS enabled applications, user interface, and distance and angle determination interfaces. The optical measuring device is preferably compact, pocket sized, and portable.
