The Bosch GLL330-80CGL 18 V 360 deg connected green-beam three-plane leveling and alignment laser with one 4 Ah battery provides an all-in-one level and alignment solution with incredible power flexibility. Versatile power options help maximize productivity and keep the laser up and running, with the ability to use the included CORE18V® 4 Ah battery or 4X C cell alkaline batteries (sold separately). Built-in VisiMax™ technology monitors temperature and power consumption to deliver the brightest line for the job, optimize energy efficiency and provide long term tool reliability. The leveling laser emits three bright green-beam laser chalk lines in 360 deg laser planes one horizontal and two vertical for high-visibility and fast job setup from one initial point. Full rubber over mold housing with a foam-reinforced interior helps protect the level at every major impact point. The laser is IP65 rated (tool only) for dust-tight and water-resistant durability in tough jobsite conditions. An integrated multi-purpose magnetic laser mount with fine adjustment and pivot rotation provides accurate point-to-point alignment for enhanced versatility. The laser has a working range of up to 115 ft and the bright, vivid thin lines provide an accuracy of 1/8 in at 30 ft. Further extend the range to 400 ft (measured at the horizontal line at 45 and 225 deg) with the levels receiver compatibility (sold separately). Equipped with a Smart Pendulum System, the tool self-levels, will indicate any out-of-level condition and then locks when switched off for secure transport. Fully featured with Bluetooth connectivity, manage the setup of the laser from across the room with a paired smartphone and the free Bosch leveling remote app. Power-saving mode and brightness adjustment options help maximize battery life. Keep a handle on the laser with the rubber-grip base and easily position using the strong magnets or 1/4 and 5/8 in threading mounts.
