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.Power flexibility – works with included CORE 18 V 4 Ah battery or 4X C Cell alkaline batteries (sold separately) for less downtime on the jobJobsite tough construction – IP65 rated, for dust-tight and water-resistant durability in tough jobsite conditionsBluetooth connectivity – allows Set up of the laser from across the room using paired smartphone and the Bosch Leveling Remote AppBuilt-in VisiMax technology – monitors power consumption to maximize line visibility and extend battery lifeIntegrated magnetic laser mount – positions and mounts with magnets or threaded mounts with fine adjustment pivot for fast and precise alignmentBright green-beam laser – projects up to 4X brighter than standard red beamsPower-saving mode – helps to increase efficiency and extend battery life by adjusting brightness of the laserAll-in-one functionality – three chalk lines in 360 deg laser planes – one horizontal and two vertical, make the tool a complete level as well as an alignment laser with simplified and speedy job setupBright, thin lines – with 115 ft range that level within 1/8 in accuracy at 30 ft distance
