Spectra Precision® LL300 Laser Level

The fully automatic, self-leveling LL300 allows for fast, accurate setup and increases productivity. The laser level’ s single cross-axis manual slope mode with cross-axis self-leveling allows for grade matching in basic slope work and maintains accuracy in the cross-slope. Waterproof and dustproof, the LL300 features “ hard hat� rotor protection and can withstand drops of up to 3 feet ( 1 meter) directly onto concrete or up to 5 feet ( 1.5 meters) when pushed over on a tripod. The included HL450 Laserometer features a 4" ( 102 mm) reception height for fast beam acquisition, and an anti-strobe sensor prevents construction site strobe lights from setting it off. The HL450 displays a digital readout of elevation on large front and rear LCD’ s to show how far the elevation is from on-grade.
