Spectra Precision LL300N-X1 Laser Package, HL760 Deluxe Receiver, TENTHS-Rod, HD Tripod and Small Case

The Spectra Precision LL300N-X1 is a complete, job-ready laser level kit engineered for contractors who demand tenth-of-foot precision on critical elevation work. Bundled with the HL760 deluxe receiver, a tenths-graduated grade rod, and a heavy-duty tripod, this kit delivers everything your crew needs to hit grade right out of the case — no extra purchases required. Whether you're screeding a concrete slab, fine-grading a parking lot, or setting drainage swales, the LL300N-X1 gives you the accuracy and reliability to get it right the first time.

Overview & Jobsite Applications

Built around Spectra Precision's proven self-leveling horizontal laser platform, the LL300N-X1 is purpose-built for single-grade applications on commercial and residential jobsites. The laser automatically levels within its 10-degree range and maintains a consistent 360-degree horizontal plane across the entire work area. Combined with the HL760 receiver — one of the most sensitive detectors in its class — this kit is fully capable of operating in bright outdoor conditions at working ranges up to 2,600 feet in diameter. The tenths rod eliminates interpolation errors and speeds up grade checks significantly on finish-critical work.

Job Applications

Concrete Flatwork & Slab Screeding: The tenths rod and HL760 receiver let your crew set and verify slab elevation quickly, reducing costly re-pours and ensuring ADA-compliant floor tolerances on commercial projects.

Finish Grading & Drainage Layout: Hit ±0.1-foot grade targets confidently on landscaping, parking lot drainage, and swale construction where close tolerances directly affect water flow performance.

Foundation Elevation Checks: Use the LL300N-X1 to verify footing and foundation wall elevations before framing begins, catching high or low spots early when corrections are still simple.

Irrigation & Utility Trench Grading: Maintain consistent pipe-fall grades over long trench runs — the 2,600-foot operating diameter means a single setup covers most residential and light commercial sites end to end.

Frequently Asked Questions

Can the LL300N-X1 be used for slope or grade-setting applications?

The LL300N is a single-grade (horizontal only) laser and does not support slope or dual-grade settings. For grade-setting applications requiring a sloped plane, consider the Spectra LL500 or a dual-grade model. The LL300N-X1 excels at flat horizontal elevation work where a consistent level plane is required.

What is the effective range of the HL760 receiver included in this kit?

The HL760 deluxe receiver extends the operating range of the LL300N to up to 2,600 feet in diameter (1,300-foot radius). Under bright outdoor sunlight the receiver picks up the beam far beyond what the naked eye can detect, making it the preferred method for all outdoor use.

Is the LL300N-X1 kit waterproof enough for outdoor use in rain?

Yes. The LL300N laser head carries an IP66 rating, meaning it is fully dustproof and protected against powerful water jets. It is designed to continue operating in rain and muddy jobsite conditions. The HL760 receiver is also weather-resistant, though it should be stored out of direct submersion.

How accurate is the tenths rod compared to a standard grade rod?

The tenths rod reads in 0.1-foot increments, allowing your crew to read and record grade directly from the rod face without converting fractions or doing mental arithmetic. This reduces reading errors on finish work and speeds up grade checks across large areas. Standard rods graduated in feet and inches require conversion math that introduces opportunity for error on tenth-critical applications.
