Johnson Level 50ft Self-Leveling Cross-Line Laser Kit with Green Beam

Johnson's self-leveling cross & line laser combines the features of a cross-line laser with an additional 90 plumb line, useful for checking square reference of beams, posts or any other object. The laser's GreenBrite technology makes the beam 400% more visible than red beams for working in high ambient light conditions. Thanks to the laser's visual out-of-level indicator, you'll never need to worry about accuracy - if the laser can't self-level, it will alert you by flashing the beam. With the included magnetic target, magnetic bracket, and tinted glasses, you'll have everything you need to get your job up and running!
