The Spectra Precision LL300N-X22-PRO is the most capable configuration in the LL300N lineup, purpose-built for contractors who demand remote slope control, rechargeable power, and extended receiver sensitivity on demanding jobsites. Whether you're managing road subgrade, complex drainage planes, or large-scale earthwork, this kit delivers the precision and workflow efficiency that separates professional-grade tools from the rest.
Product Overview & Jobsite Applications
The LL300N-X22-PRO pairs Spectra Precision's trusted dual-slope self-leveling laser head with the X22 remote control system, a rechargeable battery dock, and the deluxe HL760 receiver. Slope values can be entered and adjusted wirelessly from the machine cab or grade rod—eliminating costly walk-backs to the laser head during active grading passes. The combination of dual-axis slope capability and remote operation makes this kit the preferred choice for road construction crews, site civil contractors, and drainage engineers working across irregular terrain.

Job Applications
Road Subgrade & Paving: Set dual cross-slope and longitudinal grade simultaneously to match design drawings. Adjust crown or superelevation from the cab without interrupting the grading pass.
Site Drainage & Swale Construction: Program independent X and Y slopes to direct water flow precisely across large pad areas, parking lots, and athletic fields with a single laser setup.
Large Earthwork & Cut-Fill Operations: The 800m working diameter and deluxe receiver give machine operators reliable grade reference across expansive sites where single-axis lasers fall short.
Agricultural Land Leveling: Remote slope adjustment allows operators to fine-tune field grades on the go, maximizing irrigation efficiency and minimizing soil disturbance.

Frequently Asked Questions
- Can I control both slope axes independently with the X22 remote?
- Yes. The X22 remote allows you to adjust slope values on both the X and Y axes independently from up to 200 meters away, so you can dial in dual-plane grades without leaving your machine or grade rod position.
- How long does the rechargeable battery last on a full charge?
- The included NiMH rechargeable battery pack provides up to 80 hours of runtime under normal operating conditions, significantly reducing downtime and eliminating the recurring cost of alkaline batteries on long projects.
- Is the LL300N-X22-PRO compatible with machine control systems?
- The LL300N is designed for grade rod and receiver-based workflows. For full machine control integration, Spectra offers dedicated machine control lasers. Contact Express Tools to discuss the right solution for your equipment setup.
- What is the difference between the LL300N-X22-PRO and the standard LL300N kit?
- The PRO kit includes the X22 wireless remote control, the deluxe HL760 receiver with extended detection range, and the rechargeable battery system with dock charger—upgrades that improve efficiency on larger sites and reduce consumable costs over time.
