Description
The Bosch GLL50-20G Self-Leveling Cross-Line Laser projects two level and plumb green beams that are up to 4X brighter than standard red beams. Featuring a 65 Ft. range that allows for leveling within a 1/4 In. accuracy at 30 Ft., it’s a must-have for any tool bag. With its power flexibility, operate using the included AA batteries or purchase the Bosch 3.7V Lithium-Ion 1.0 Ah Battery (sold separately) that can even be used while charging to diminish downtime. Built-in VisiMax™ Technology optimizes line visibility and runtime for working conditions to further maximize usage. Its ergonomic, compact, lightweight design and IP55 dust- and water-resistant rating, provide for both comfortable and dependable operation. The full rubber overmold housing helps protect every major impact point, acting like a roll cage to safeguard the tool. Equipped with a Smart Pendulum System, the tool self levels, will indicate any out-of-level condition by blinking and then locks when switched off for secure transport. Simply tilt the laser to use the lines at an angle with ease. Position the tool with the included integrated magnetic mount or utilize the 1/4 In. threading mount that fits with like-sized tripods.
