The Bosch GLL50-20GL Green-Beam 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 feet range that allows for leveling within a 1/4 inch accuracy at 30 feet, it’s a must-have for any tool bag. With its power flexibility, operate using the included Bosch 3.7V Lithium-Ion 1.0 Ah Battery that can even be used while charging to diminish downtime or with two AA batteries (sold separately). 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 inch threading mount that fits with like-sized tripods.

Great quality and saved heartache
Best thing I could have gotten for myself with my wife always questioning if painting or pictures are straight or lined up. This thing puts that to rest and makes it way easier. Love this thing

Great laser
Really think that I’m going to enjoy using this laser. It’s my first one with a green beam & it’s amazing how much brighter it is.

Great brand, great product
Bought this for my boyfriend and he absolutely loved it. It is extremely easy to use and install and has the perfect size. There are a lot of cheaper brands out there, but since this was a gift, I wanted it to be a good and known quality name.

easy to use, used to line up posts heights for raising our deck at the lake 30″, outside work but we could see the lines quite well during the day up to about 25′ but had to use a white surface to located the lines at about 30′, still worked well and the deck supports were perfectly level using the measurements from the laser level (-:}
