Spectra Precision LL300S


The Spectra Precision® LL300S Laser Level features a rugged design with a metal sunshade that provides superior drop and weather protection (IP66). Designed for durability and reliability, the IP66 protection rating allows the Spectra Precision® LL300S to be operated in adverse environmental conditions, such as heavy rain. Mud and concrete can be washed off with a hose. The LL300S can withstand drops of up to 1 meter onto concrete and tripod tip-over up to 1.5 meters, resulting in reduced downtime and lower repair costs.
