Product Description
Professional Dual-Grade Laser for Complex Grading Work
The Spectra Precision LL300N-X22 is a field-proven dual-grade laser level engineered for contractors who need precise single and dual-slope capability across demanding jobsite conditions. Packaged with a deluxe receiver and an inches-graduated rod, the LL300N-X22 is purpose-built for crews working in imperial measurements on varied terrain. Whether you're cutting pad grades, establishing drainage slopes, or laying out complex multi-plane surfaces, this laser delivers the accuracy and flexibility professional grading work demands.
Jobsite Overview and Applications
The LL300N-X22 handles the full range of grading and layout tasks encountered on residential, commercial, and civil jobsites. Its switchable single and dual-slope modes let operators dial in straightforward flat grades or independently control X and Y axis slopes without repositioning the instrument. The self-leveling system gets the laser plumb and ready fast, while the rugged housing stands up to dust, moisture, and the vibration common on active sites. The included deluxe receiver displays real-time grade readout and slope percentage, keeping grade checkers informed whether they're working close in or out at range.

Job Applications
- Site Grading and Pad Preparation: Set precise flat or sloped grades across building pads, parking areas, and rough grading operations with single-slope mode for fast, repeatable results.
- Drainage and Swale Layout: Use dual-slope mode to simultaneously control fall in two directions, ideal for parking lot drainage, agricultural land forming, and stormwater management grading.
- Foundation and Footing Layout: Establish consistent elevation benchmarks around a foundation perimeter, ensuring footings and stem walls meet spec before concrete placement.
- Pipe and Utility Trenching: Maintain consistent invert grades over long trench runs for sewer, storm drain, and utility installations where consistent fall is critical to system performance.

Frequently Asked Questions
- What is the difference between the LL300N-X22 and other LL300N kit configurations?
- The X22 kit pairs the LL300N laser with the deluxe receiver, which shows real-time grade percentage and slope on an easy-to-read display, and includes an inches-graduated rod. Other kits may include metric rods or standard receivers without the grade readout feature. Choose X22 when your crew works in imperial units and needs on-rod grade feedback.
- Can the LL300N-X22 be used for vertical applications like plumbing walls?
- The LL300N is optimized for horizontal grade and slope work. For vertical layout and plumb transfer, a laser level with a plumb or vertical beam function would be more appropriate. The LL300N excels at site grading, drainage, and elevation control tasks.
- How do I enter a specific slope percentage on the LL300N?
- Slope values are entered manually through the instrument's control panel. You can set grade values from 0 to 50% on one or both axes depending on whether you're in single or dual-slope mode. Refer to the operator's manual for the step-by-step input sequence, or see our setup guide linked above.
- Is the LL300N-X22 compatible with machine control systems?
- The LL300N is designed primarily for hand-grade and rod-and-receiver operations. For full machine control integration on dozers, scrapers, or graders, Spectra Precision offers dedicated grade control systems. Contact Express Tools to discuss the right solution for machine-mounted applications.
Why This Equipment
Auto Self-Leveling
Compensates for job site movement and setups — no manual leveling required.
Long Range
Reach 2,600+ ft with a receiver — covers large pads and site-wide grading without moving.
IP55+ Protection
Dust-tight and water jet resistant — built for outdoor construction in any weather.
Radio Remote
Change grade or elevation from the cab or anywhere on site without walking back.
The right rotary laser pays for itself in weeks.
A grade checker costs $600–800 per day. A quality rotary laser setup eliminates that cost indefinitely — and works faster. One operator with a good laser and receiver can cover ground that used to take a two-person crew.
The gap between a budget unit and a professional-grade one shows up in the field: self-leveling range on uneven pads, IP55+ protection through rain and dust, and radio remote control so you're not walking back to the instrument every time the job moves.
Express Tools is an authorized dealer with genuine, factory-fresh inventory and same-day shipping on in-stock units. We know this equipment and can answer spec questions before you order.
