Description: This robust rotary laser is perfect for precise levelling of horizontal and vertical surfaces over extremely long distances. Available modes include spot, scan, rotary and hand-held receiver. The device aligns itself automatically to save time and has simple one-button operation. All functions can be controlled remotely up to a distance of 40 metres. In the event of external influences, automatic switch-off ensures measurement errors are avoided. A special motor brake provides excellent protection during transportation. The receiver has a large reception range of 400 metres. LC displays on the front and rear of the device, bright, three-colour LED signals, and acoustic signals indicate the height of the laser beam.
