Features

Medium-range, highly accurate leveling solution. 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 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 tip over 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. Increases productivity with fast setups, fewer mechanical parts, and automatic self-leveling. Maintains performance even in rainy, dusty and other harsh job site and weather conditions. Durable design reduces downtime due to drops and tripod tip overs. Minimizes power costs, increases reliability with choice of rechargeable or alkaline batteries. Increases flexibility with remote control slope option. The HL450 Laserometer features a digital readout of elevation that provides a numeric display of ±1.5" or ±38 mm. The readout is displayed on the large front and rear LCD’s and shows exactly how far the elevation is from on-grade. It has a large 4" (102 mm) reception height for quick beam acquisition. An anti-strobe sensor prevents construction site strobe lights form setting it off.
