The GLL 3-80 C Professional line laser is simply connected and provides excellent visibility via the projection of 3 x 360° lines. Thanks to innovative CAL Guard monitoring and Bluetooth® connection to the smartphone app, remote control, contactless adjustment and high precision are possible. Powerful diodes guarantee high visibility, while 3 x 360° lines ensure simultaneous horizontal and vertical leveling and thus high work efficiency.This line laser was developed for the construction of floors, the assembly of windows, the installation of shelves, the laying of drainage pipes, the rough construction for drywall and the laying of tiles.Thanks to dual power source technology of the GLL 3-80 C Professional, operation is possible with both 12 V Li-ion battery and standard alkaline batteries, a plus in flexibility. The device is able to self-level on non-planar surfaces in less than 4 seconds with an excellent accuracy of ± 0.2 mm/m by +/- 4° and has a working range of 120 m when using the optional receiver LR 6 or LR 7 Professional This line laser is compact, easy to use and extremely robust.
