Description:  This long range, fully automatic rotary laser is ideal for excavation work. The robust device provides precise levelling of horizontals, verticals and slopes. A 90° reference beam provides plumb-lining and aligning for partitions. Green laser technology provides excellent visibility. Available modes include spot, scan, rotary and hand-held receiver. The combination of light-weight tripod, laser receiver and measuring staff is ideal for determining and working with reference dimensions. All functions can be easily controlled with the remote control up to a maximum distance of 30 metres. In the event of external influences, the device shuts down automatically to prevent measurement errors. The battery pack can be used and charged at the same time which means users can work without interruption.
