The Spectra Precision Laser LL300 features a rugged design with "hard hat" rotor protection that provides superior drop and weather protection.
The LL300's fully automatic self-levelling capability provides fast, accurate setup. Alkaline batteries keep the unit working with no downtime due to power loss. Single cross-axis manual slope mode with cross-axis self-levelling allows grade matching for basic slope work, while maintaining accuracy in the cross-slope.
Features & Benefits:
· Increases productivity with fast setups, fewer mechanical parts, and automatic self-levelling
· Maintains performance even in rainy, dusty and other harsh job site and weather conditions
· Durable design reduces downtime due to drops and tripod tip-over
· Minimizes power costs, increases reliability with choice of rechargeable or alkaline batteries
· Increases flexibility with remote control slope option
· Comes with HL450 receiver
Applications:
· Checking/setting elevations, concrete forms, footings, and foundations for small- and medium-sized jobs
· Basic slope work such as driveways and ramps
· Excavations, digging footings and septic tanks
