The digital level is the most accurate on the market with a .01-Degree accuracy. It is nearly 3X more accurate than the most accurate spirit levels on the market. Other features include an automatic shut off after continual non use, so it does not to waste battery power. Also, if turned upside down, the screen will automatically adjust so you can read it without any problems.
