BOSCH GLL 3-80 Professional 3 x ° Line Laser

The Bosch GLL 3-80 Professional 3 x 360° line laser is a self-levelling line laser for professional construction, installation, and interior fitting work. It projects three 360° red laser lines — one horizontal and two vertical — from a single position, covering ceiling, floor, wall, and reference planes across an entire room. This allows levelling, alignment, and marking for tasks such as window, shelf, and pipe installation, tiling, and general interior fitting without repositioning. The unit achieves a levelling accuracy of ±0.3 mm/m, with a standard working range of 30 m. Range extends to 120 m when paired with a compatible receiver for larger outdoor or open-plan applications.

The IP54-rated housing resists dust and water splashes for reliable operation on demanding job sites. Four included AA alkaline batteries deliver up to four hours of continuous operation. An integrated battery level indicator helps track remaining charge during extended work sessions. A pendulum lock secures the internal levelling mechanism during transport to prevent misalignment. The unit supports tripod mounting via both 1/4-inch and 5/8-inch threads for stable fixed-position use. Bosch includes a target card alongside the batteries in the package.
