The Spectra Precision Laser LL300 features a rugged design with "hard hat" rotor protection that provides superior drop and weather protection. Built to withstand severe drops of up to 1 m directly onto concrete, or up to 1.5 m when pushed over on a tripod means less downtime and cost due to damage caused by accidental drop or tipover - and lower repair costs over the life of the product.
The LL300's fully automatic self-leveling capability provides fast, accurate setup. Rechargeable Ni-Cad battery pack or alkaline batteries keeps the unit working with no downtime due to power loss. Single cross-axis manual slope mode with cross-axis self-leveling allows grade matching for basic slope work, while maintaining accuracy in the cross-slope.
