Green Beam Self Leveling Cross Line Laser with Plumb Points uses Green Beam technology, which emits green lines and points up to 4X brighter than standard red beams. This gives the laser a working range for the lines of up to 165'. The laser produces vertical, horizontal, cross line modes, as well as upward and downward green plumb points. The tool can project two lines independently or together, for a broad array of alignment and leveling applications. It includes Bosch-exclusive VisiMax technology, which monitors tool temperature and power consumption to deliver the brightest line for the job.
