Most levels can only read level and plumb, but the SmartTool Digital Level  can read angles in a 360° range. The user can recalibrate the Smart Level in seconds, this means you can always rely on the Smart level to be reading true. Smart levels read in degrees, % slope or metric pitch. The smart level also has two built-in spirit bubbles for quick level and plumb checks. The Smart Level has an accuracy of 1/10 of a degree.
