Medium-range, highly accurate leveling solution The Spectra Precision® LL300N Laser Level features a rugged design with a metal sunshade that provides superior drop and weather protection (IP66). Built to withstand severe drops of up to 3 ft (1 m) directly onto concrete, or up to 5 ft (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 LL300N’s fully automatic self-leveling capability provides fast, accurate setup. Rechargeable NiMH 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. Receiver options include the advanced HL450 Digital Readout receiver or the traditional HR320 receiver.
