12V Max Connected Cross-Line Laser with Plumb Points

The Bosch GCL100-80C 12 V Max Connected Cross-Line Laser with Plumb Points delivers all-in-one versatility, with highly visible lines and points. They provide horizontal level, vertical alignment and plumb point transfer applications. The tool features Bosch-exclusive VisiMax™ technology, which monitors tool temperature and power consumption to deliver the brightest line for the job.. The laser features Bosch 12 V Max Lithium-ion power for extended laser runtime during complex or all day layout jobs, provides a visible range of 100 Ft. and can work with an optional Bosch laser receiver to extend that range to 165 Ft. The Smart Pendulum System self-levels up to ±4°, indicates out-of-level condition and locks for safe tool transport. The manual mode locks lines for use at any angle. The laser comes with the RM 2 Magnetic Rotating Mount that rotates 360°, has a micro-fine adjustment knob and includes a ceiling grid clip.
