The sturdy, fully automatic rotary laser is perfect for precise alignment of horizontals. Furthermore, the device can be used for the levelling of verticals and slopes. Aligning partitions is easy thanks to an additional reference beam. The laser receiver can be easily attached to measuring staffs and allows a height reference to be marked. This has the advantage that the laser can be reset to the specified height at any time. The remote control for operating all of the functions at a distance of up to 40 metres is particularly handy. In the event of external influences, the automatic shut down prevents measurement errors. The HighCapacityPack with lithium-ion technology can be used and charged at the same time which means users can work without interruption.
