The Spectra Precision LL300N-X11 delivers everything a contractor needs for reliable tenth-of-foot accuracy on demanding jobsites. This turnkey package combines the proven LL300N rotary laser with a deluxe dual-mode receiver, a graduated tenths rod, and a heavy-duty reinforced tripod—eliminating the need to source compatible components separately. Whether you're setting finish grades, laying utility lines, or checking drainage fall, the LL300N-X11 gives your crew a repeatable, field-ready setup from day one.
Package Overview & Jobsite Applications
The LL300N-X11 is purpose-built for contractors who need consistent grade control without the overhead of remote-managed systems. The LL300N's self-leveling mechanism compensates for up to 2 degrees of out-of-level setup, keeping the beam locked and reliable even on uneven ground. At 300 meters of effective working range, the package handles everything from small residential lots to large commercial pads. The deluxe receiver's dual-mode operation lets crews alternate between manual grade checks and automated cut/fill indication, adapting to how each foreman runs their workflow. The pre-graduated tenths rod eliminates field conversion errors that cost time and introduce risk on finish-grade and drainage-critical work.

Job Applications
Finish Grading & Site Drainage: The tenths rod lets operators read grade directly in feet and tenths, eliminating mental conversion on slopes as shallow as 0.1%. Ideal for parking lots, athletic fields, and drainage swales where fall tolerances are tight.
Utility & Sewer Line Layout: Consistent elevation control along long trench runs is straightforward with the 300-meter range and a rod-mounted receiver. Crews can check invert elevations and pipe fall without repositioning the instrument.
Concrete Flatwork & Slab Elevation: Set screeds and check pour elevation against design grade quickly. The 600 RPM rotation speed keeps the beam visible on receivers across large slabs, even in bright daylight conditions.
Landscape & Agricultural Grading: The LL300N's long battery life—up to 100 hours—means all-day operation without battery changes, making it practical for large grading passes on landscape or agricultural projects.

Frequently Asked Questions
- Does the LL300N-X11 include a remote control?
- No. The X11 configuration does not include a remote control. It is optimized for hands-on operation and is ideal for contractors who prefer direct instrument control or primarily work solo. The Spectra RC601 remote is available separately and is compatible with the LL300N if remote operation becomes a priority.
- Can the included receiver be used with other Spectra rotary lasers?
- Yes. The deluxe receiver included in the X11 package is compatible with other Spectra Precision visible-beam rotary lasers that operate in the standard frequency range. Confirm compatibility with your specific model before pairing with a different instrument.
- What does "tenths rod" mean and why does it matter on the job?
- A tenths rod is graduated in feet and tenths of a foot rather than feet and inches. Since most civil grading plans express elevations in decimal feet, reading a tenths rod directly eliminates the conversion step that creates errors and slows down rod work. For drainage or finish-grade work specified to 0.1 ft., it's a meaningful workflow improvement.
- Is the LL300N-X11 suitable for indoor use such as suspended ceilings or concrete pours?
- The LL300N is primarily designed for outdoor horizontal grade applications. While it can be used indoors for floor elevation checks and slab pours, it does not offer a manual slope mode or vertical plumb function. For suspended ceiling grid work or multi-plane interior layout, a laser with manual grade or multi-axis capability would be more appropriate.
