Reading Ruler is a digital tape. Created by Ho Sung-woon and Woo Bum-Moo, this meter has a digital display on the bright side. Day or in darker areas there will be no trouble using it. The icing on the cake, Reading Ruler is an excellent converter, the measurements are displayed in different units of measure: meters, inches, feet, etc.
This high-tech tape measure has some similarities with Silk, also digital and intelligent, but it will not help you more than a traditional meter in a poorly lit.
