From the Manufacturer SmartTool electronic level all ready to go in a 2 ft. long aluminum frame. Only SmartTool electronic level can measure all angles in a 3600 range. Installing a deck, stair rail, extending a roof, or determining how much an old floor has sagged is simpler and less time consuming. The display even flips over with the level, and it shuts off automatically after 5 minutes when it is not being used, all this from a standard, 9-volt battery (not included). Features: angle accuracy to 1/10 of a degree, the mode button lets you see angles in three ways-degrees, percent slope or pitch (inches of rise per foot of run), and Listen & Level ideal for poorly lit areas. Also allows hands-free operation as the audible tone alerts you when tool reaches level or plumb. Please note that the module cannot be removed from the rail.
