The Datum DUO DUAL GRADE Laser uses a high quality 3 axis electronic compensator
for accurate automatic levelling. It is a visible beam model, and so can be used
either internally or externally, with a Dual Grade range of ±10% including an XY
memory system to retain the grade settings after power off. An out of level warning
system alerts the user if the Laser is disturbed or knocked.
The DUO DUAL GRADE laser can be used on its side for vertical alignment operations
suitable for both internal and exterior use.
Supplied complete with Sighting Telescope, Remote Control, Detector, Clamp, Battery
Pack, Alkaline Battery Housing Cover, Charger, Wall Mount, Magnetic Target and Protective
Carry Case.
