The Bosch GCL100-40G 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 up to 165 ft. The laser produces vertical, horizontal, cross-line modes, as well as upward and downward green plumb points. The tool can project 2 lines independently or together, for an 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. The tool has full rubber overmold housing, designed to be similar to a roll cage, so every major impact point is reinforced with rubber. The Bosch Smart Pendulum System self-levels and indicates out-of-level condition, and locks the pendulum for secure transport. The Bosch BT 150 compact tripod with adjustable legs allows the user to work at precise heights ranging from 22 in. to 61 in. The tripod has a fine adjustment crank that allows for quick setup with the benchmark. The 1/4 in. mounting thread makes it compatible with Bosch line lasers, point lasers and laser measures.
