| Spectra Precision LL300N Laser OVERVIEW |
The Spectra Precision LL300N is a high-precision, self-leveling rotary laser built for construction and survey applications. This base package pairs the LL300N laser with the HL450 Laserometer receiver — ideal for contractors who already have a tripod and grade rod, or who need a compact laser-and-receiver setup for a specific task.
The LL300N delivers 3/32-inch accuracy at 100 feet across a 1,650-foot diameter operating range, making it 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 LL300N’s fully automatic self-leveling provides fast, accurate setup. 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 using the optional RC601 remote control.

| HL450 Laser Receiver / Laserometer DETAILS — Included with the LL300N |
The Spectra HL450 Laser Receiver — a highly versatile receiver for basic and advanced leveling and aligning
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 ±40mm or ±1.5 inches. The readout is displayed on the large front and rear LCDs 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 signal.
The Laserometer is designed to survive 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 reach 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 4-inch 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.
HL450 Laser Receiver Applications — Setting and checking jobsite elevation and depth for:
- Cut and fills
- General grading
- Foundations, forms, and footings
- Excavations
