The Klein Tools 935DAGL is a digital level tool that detects and measures angles much more accurately than traditional spirit bubble levels. This inclinometer can measure ranges from 0 to 90-Degree or 0 to 180-Degree with a display that rotates when used in vertical or horizontal orientations. A target angle with audible alarm can be set, allowing the user even greater efficiency. The V-groove magnetic base can attach to a miter saw, table saw, conduit, pipe, and other round or ferromagnetic surfaces.
