The Spectra Precision HV302GC-1 is a complete red beam rotary laser system engineered for general contractors, grading crews, and finish carpenters who need reliable horizontal and vertical control across a wide range of interior and exterior applications. This turnkey package arrives job-site-ready with every accessory needed to begin layout work immediately, reducing downtime and equipment sourcing headaches.
System Overview & Jobsite Applications
Designed to handle the demanding conditions of active construction sites, the HV302GC-1 combines a high-accuracy self-leveling rotary laser with a long-range remote control receiver setup. Whether you are grading a pad, setting form boards, transferring elevations across a building floor, or plumbing walls, this system delivers consistent, repeatable results. The included HL760 receiver extends working range beyond what the naked eye can detect, making the package equally capable indoors under bright shop lighting and outdoors in direct sun.

Job Applications
Site Grading & Excavation: Use the single-axis grade function to set cut-and-fill elevations for drainage slopes, driveway pads, and foundation excavations without manual calculations at each stake.
Foundation & Formwork Layout: The horizontal plane projection lets crews set batter boards and form panels to a consistent elevation around the full perimeter of a structure, eliminating cumulative measurement error.
Interior Finish Work: Project a vertical reference plane to align stud walls, dropped ceilings, tile layouts, and cabinet runs across large open floor plans where a chalk line is impractical.
Utility & Pipe Installation: Combine grade mode with the measuring rod to establish consistent pipe slope and invert elevations, reducing rework on underground rough-in.

Frequently Asked Questions
- Can the HV302GC-1 be used outdoors in sunlight?
- Yes. The included HL760 receiver detects the red beam in bright ambient light conditions at distances up to 2,000 ft in diameter, where the beam would otherwise be invisible to the naked eye.
- Does this package include a remote control?
- Yes. The RC402N wireless remote control is included and operates the laser from up to 600 ft away, allowing a single operator to adjust rotation speed, grade settings, and power without returning to the instrument.
- What is the grade range of the HV302?
- The HV302 supports single-axis grade matching up to ±25%, which covers the vast majority of drainage, roadway, and ADA-compliant ramp applications encountered on general construction projects.
- Is the HV302GC-1 covered by a warranty?
- Spectra Precision backs the HV302 with a limited warranty covering defects in materials and workmanship. As an authorized dealer, Express Tools ensures every unit is sourced through official channels so your warranty registration is fully supported.
