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.

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.

The Laserometer is designed to survive the tough construction site conditions. It is totally waterproof and can withstand a drop up to 5-feet onto concrete.

Spectra HL450 Laserometer Features and Benefits:

Digital Readout of Elevation allows faster readings by displaying the exact numerical distance from grade, eliminating the need to move the receiver to get to "on-grade".
Anti-Strobe Sensor stops construction strobe lights from setting off the receiver and eliminates phantom strikes for easier identification of true laser beam signals.
Large reception height allows faster readings by acquiring the beam quickly, and makes it easier to stay in the beam.
Durable in tough environments provides less downtime due to damage or service requirements after accidental drops.
