Description:  This cross-line laser has a green laser cross and three red laser lines for precise vertical and horizontal levelling. The upper laser cross and the additional plumb laser allow the floor and ceiling to be worked on at the same time. The device can be easily set up in advance using the vial and the height-adjustable feet. The rotatable housing with vernier adjustment mechanism allows the laser line to be precisely positioned. To prevent incorrect measurements, optical signals warn the user when the device is outside the levelling range. Other positive features include the powerful lithium-ion battery for extended periods of operation and a pendulum locking system for safe transportation. When combined with the optional CombiRangeXtender 40, the integral handheld receiver mode allows the red and green laser lines to be detected over long distances and in unfavourable light conditions.
