It is designed by Huang Qiaokun. The Red Point Measure is a digital measure that applies current laser ray measure techniques to mathematics formula of triangles by simply measuring a target from afar. By using the laser beam measurement technology and a simple mathematical formula triangle principle.

 

 

Its also really easy to use. Once turned on two visible red laser beams will come out from its “arms”, leaving a small red marker point on the surfaces. All you have to do is open or close the measurement device so the red markers are where your measure tape should have been. Press a button and the Red Point Measure will tell you the exact distance between the two markers.
