 Spectra LL300


LL300S rotating laser

Spectra LL300S laser level prepared to perform at all times.

The Spectra LL300S Laser Level features a rugged design with “hard hat” rotor protection that provides superior drop and weather protection. 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. With the addition of the grade arrow buttons, grade matching can be performed while the other axis remains self leveled.
