Johnson 40-6544 Laser Level Kit, Green Laser

Designed for the advanced laser user, this rotary laser kit is feature-packed to tackle any job - indoor or outdoor. The laser's GreenBrite® technology makes the beam 400% more visible than red beams for working in high ambient light conditions. The laser self-levels both horizontally and verticaly, making vertical layout projects such as fencing, footings and drywall track quick and easy. Its electronically controlled dual-slope mode takes math out of the equation when checking grade or setting drainage. And the laser beam modes include dot, two adjustable line lengths and two rotational speeds (200 and 500 rpm). It features visual and audible alerts when it is beyond its leveling range.
