Johnson Level 30ft Self-Leveling Cross-Line Laser Kit with Green Beam

Cross-line laser levels offer the highest value of any type of laser: they're extremely versatile and easy to use. The laser's GreenBrite technology makes the beam 400% more visible than red beams for working in high ambient light conditions. It projects two crisp, clean laser lines simultaneously - one vertical and one horizontal. It also features a manual mode for use at any angle for working on stairs or other non-level projects. 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.
