The GLL 100 G self-leveling cross-line laser is the first green laser level from Bosch. Green light lasers are up to four times brighter than traditional red beams, according to the company, so they provide more visibility in bright ambient light conditions. Green lasers are optimal for jobs requiring a greater distance—the laser on this tool is visible up to 100 feet. The cross-line laser includes conventional vertical, horizontal, and cross-line modes, which can be used independently or together. The laser can be purchased for $270.
