Bosch's electronic level is easier to use than a spirit level and performs some functions that a spirit level cannot. The readout displays directional arrows, and the level produces an audible tone when the tool is at 0 or 90 degrees. Slope can be read in degrees, percent, or inches per foot. The tool is made from aluminum and — according to the maker — will provide close to 200 hours of runtime on a 9-volt battery. It comes in 2-foot (DNM 60L) and 4-foot (DNM 120L) lengths and is sold with a padded carrying case.
