Spectra Precision LL300N-4 Laser Package with HL450 Receiver and Rechargeable Batteries

The HL450 — Spectra's Standard Rod-Mounted Laser Receiver

When you're working on grade — setting forms, checking elevations, or grading a pad — you need a receiver that picks up the beam fast and tells you where you stand. The Spectra HL450 is a field-proven, no-nonsense rod-mounted receiver built for everyday construction use. It gives you a precise digital readout of exactly how far above or below grade you are — no guesswork, no moving the clamp to find on-grade, just a number on screen and you're moving.

What the HL450 Delivers on the Job:

Ideal Applications

Site Grading & Excavation

Drainage & Pipe Laying

🚜 Farm & Land Leveling

🏠 Foundation & Footing Work

Elevation Checks & Surveying

△ PRO TIP — Need to Run Slope? You Need This Remote.
Without the RC601, this laser operates in flat/level mode only. If your job requires matching a grade — driveways, drainage ditches, ramps, or any single-axis slope — the RC601 is not optional, it’s essential. One person can dial in slope from the rod position without walking back to the laser. No helper needed.

What the RC601 does for you on the job:

• Set and adjust slope from the rod position — no back-and-forth to the laser
• Run single-axis manual slope with cross-axis self-leveling maintained automatically
• One-person slope operation — saves time and eliminates the need for a second crew member
• Works up to 160 feet from the laser
• Compatible with this kit out of the box — no additional hardware required
