The Spectra Precision HV302GC-1-NR is a professional-grade dual-plane laser level kit engineered for contractors who demand decimal-precise elevations and reliable performance across interior and exterior jobsites. Combining the HV302 self-leveling red beam laser with the HL760 remote-capable receiver and a GR151 grade rod graduated in tenths, this kit eliminates field reading ambiguity and reduces costly rework on high-accuracy applications.
Kit Overview and Jobsite Applications
Built for demanding construction environments, the HV302GC-1-NR delivers simultaneous horizontal and vertical plane projection for fast, accurate layout and grade work. The self-leveling mechanism compensates for minor tripod settlement and uneven terrain, keeping the beam reference true throughout the workday. The HL760 receiver extends usable range well beyond unaided eye detection, making this kit practical on sun-drenched exterior sites, large concrete pours, and expansive grading operations where direct beam visibility is impossible. The GR151 rod's decimal graduations align with engineer-specified tolerances, supporting precise elevation transfer without conversion math in the field.

Job Applications
Concrete Flatwork and Slab Elevation: The decimal rod graduations let finishers set and verify slab elevation to 0.01 ft, matching structural drawing tolerances without manual conversion from fractions.
Site Grading and Drainage Slope: Use the horizontal plane with the HL760 receiver across large grading footprints to establish consistent cut-and-fill elevations and verify positive drainage slopes before compaction.
Interior Framing and Mechanical Layout: The vertical plane projects a precise plumb reference for wall layout, column alignment, and mechanical rough-in across multi-story interior spaces.
Utility and Pipeline Grade: Decimal rod readings support consistent invert elevations for underground utility installation where slope tolerances are specified in hundredths of a foot.

Frequently Asked Questions
- Can the HV302GC-1-NR be used outdoors in direct sunlight?
- Yes. While the red beam is difficult to see with the naked eye in bright conditions, the included HL760 receiver is specifically designed for outdoor use and detects the beam reliably at distances up to 2,000 ft in full sunlight, making the kit fully functional on exterior sites.
- What does the GR151 rod being graduated in tenths mean for field work?
- The GR151 is graduated in decimal feet at 0.01 ft (one-hundredth foot) increments rather than fractional inches. This matches engineer and civil drawing conventions, eliminates inch-to-decimal conversions in the field, and reduces reading errors on elevation-critical work like slabs, utilities, and grading.
- Does the HL760 receiver work with other Spectra Precision lasers?
- The HL760 is compatible with a broad range of Spectra Precision and Trimble red-beam rotating lasers. However, remote control functionality is only activated when paired with compatible transmitters. Confirm compatibility with your specific laser model before purchasing as a standalone receiver.
- Is this kit suitable for interior partition layout as well as grade work?
- Yes. The HV302 projects both a horizontal reference plane and a vertical plane simultaneously, making it effective for interior framing, wall layout, and plumb column alignment in addition to elevation and grade applications. The dual-plane capability makes it a versatile single tool for most commercial and residential construction tasks.
