The Spectra Precision Laser LL300N package is your complete medium-range, high-accuracy solution. Ideal for basic slope work such as driveways and ramps, checking or leveling elevations, concrete forms, footings and foundations for small -and- medium sized jobs, and for excavations, digging footings and septic tanks.
The Spectra LL300N 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-feet directly onto concrete, or up to 5 feet 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 Spectra LL300N'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.

HL450 Laser Receiver / Laserometer - Included with Full Package:
The Spectra Precision® HL450 Laserometer is an easy-to-use tool that accurately measures elevations across the site, and is ideal for use with any rotating transmitter.
The HL450 features a digital readout of elevation that provides a numeric display of ± 40 mm or ±1.5 inches. The readout is displayed on the large front and rear LCD’s and shows exactly how far the elevation is from on-grade. Accurate measurements can be made without moving the rod clamp, saving time and increasing productivity.
The HL450 has a 4-inch reception height, double the typical industry standard, which allows quick acquisition of the laser beam. Also included is a patented anti-strobe sensor that prevents construction lights from setting off the receiver and makes it easier to identify the laser beam signals.
