Ultra Scale Master Pro 6260 Sonic Digitizer By Calculated Industries
Area Takeoff Tool and Digitizer System. 

The Ultra Scale Master® Pro is an affordable and portable area takeoff and digitizing system. Unlike expensive digitizers, the patented Ultra Scale Master® Pro allows you to measure plans at your office or on the job site without the need for additional computing devices or software. The ergonomic design with large targeting window allows you to accurately measure and compute areas, segment lengths, perimeters, and volumes for simple or complex polygons, polylines, irregular shapes, arcs and circles. 72 built-in architectural and engineering scales allow you to measure plans and drawing up to 24" x 36" in size. Four custom scales allow you to measure out of scale drawings. The Ultra Scale Master® Pro can operate as a stand alone digital area takeoff tool, or you can connect it to your PC to transfer measurements into any estimating and spreadsheet program that accept text input from a number pad or keyboard.
