The Bosch GLL300-42GL 3.7 V 360 deg green-beam three-plane leveling and alignment laser 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 with the included rechargeable 3.7 V Li-ion 3 Ah battery, AA batteries or even use while charging with the included USB-C cord. Built-in VisiMax™ technology optimizes line visibility for working conditions to further enhance accuracy and battery life. 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, streamlined job setup from one initial point. Full rubber overmold housing helps protect the level at every major impact point. IP65-rated, the laser can withstand tough, rainy conditions and is dust tight for enhanced protection. The laser has a working range of up to 100 ft and the bright, vivid, thin lines provide an accuracy of 1/8 in at 30 ft. Further extend the range to 260 ft (measured at the horizontal line at 135 deg and 315 deg) with the level's receiver compatibility. 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. Power saving mode and brightness adjustment options help maximize runtime and battery life. Keep a handle on the laser with the rubber grip base and easily position using the 1/4 in and 5/8 in threading mounts.
