Johnson's 12" digital magnetic laser level is a must-have at home or on the job. It provides measurements in five units of measure (degrees, percent, mm/m, in/ft - decimal and in/ft - fractional). Reading those measurements is easy under any conditions - the LCD screen rotates for easy top reading while the digital measurement readings automatically invert when you are taking overhead measurements. Even dimly lit areas don't pose a problem thanks to the level's backlight feature. The level has audible level and plumb indicators for ease of use and features a laser beam to easily transfer reference points. Powerful GripTight™ rare earth magnets hold to ferrous metal surfaces, and calibrating the tool is quick and easy at the press of a button. The level comes with a soft-sided pouch to keep your tool clean and safe when not in use.
