The three-dimensional, highly visible laser projects a horizontal line and two vertical circles for precise alignment of objects. For simultaneous work on the floor and ceiling, the laser crosses form a plumb function. The laser lines can be switched on and off individually, and in case of external interference, the anti-drift system ensures automatic shutdown to prevent incorrect measurements. With the clamp and wall mount, the laser can be hung, securely fixed to metallic surfaces, or attached to ceiling profiles. The powerful HighCapacityPack with lithium-ion technology provides a long operating time, which can even be doubled with an additional battery.
