The Spectra Precision HV302GC-X22 is a contractor-ready dual-grade laser package built for general construction crews who need reliable horizontal and vertical reference planes on the jobsite. Whether you're setting elevations for concrete flatwork, aligning structural walls, or establishing grade control on exterior layout projects, this complete kit delivers the precision and range to get the job done right. The package ships with every component you need to be productive from day one — no hunting for compatible accessories, no compatibility guesswork.
Package Overview & Jobsite Applications
The HV302GC-X22 centers on the HV302GC red beam rotating laser, a rugged self-leveling instrument capable of projecting both horizontal and vertical planes simultaneously. With a working range of up to 2,000 feet in diameter when used with the included HL760 receiver, this system is equally at home on tight interior fit-out jobs and open exterior construction sites. The RC402N radio remote control lets operators adjust settings and start or stop rotation from up to 200 feet away, eliminating unnecessary trips back to the instrument. The 16-foot grade rod graduated in inches provides precise rod readings for elevation transfer and differential leveling tasks, while the heavy-duty aluminum tripod ensures a stable, repeatable setup on uneven ground. The hard-shell carrying case keeps all components organized and protected between jobs.

Job Applications
Concrete Flatwork & Slab Layout: Establish a precise horizontal reference plane across large pour areas. Use the HL760 receiver on the grade rod to verify slab elevation and control screeding height, even in bright daylight conditions where the red beam is not directly visible.
Structural Wall Plumb & Alignment: Switch to vertical plane mode to align CMU walls, tilt-up panels, or wood-frame bearing walls. The HV302GC projects a sharp vertical reference line that crews can reference from multiple points simultaneously.
Interior Fit-Out & MEP Coordination: Set consistent ceiling heights, align suspended grid systems, and coordinate mechanical, electrical, and plumbing rough-in elevations on multi-trade interior projects — all from a single instrument setup.
Site Grading & Drainage Layout: Use the manual dual-axis grade mode to match existing slope or establish designed grade on drainage swales, parking lots, and building pads. The RC402N remote keeps the operator at grade rod location for efficient single-person operation.

Frequently Asked Questions
- Can the HV302GC-X22 project both horizontal and vertical planes at the same time?
- Yes. The HV302GC is capable of projecting simultaneous horizontal and vertical rotating planes, making it useful for both elevation control and wall alignment without reconfiguring the instrument between tasks.
- Does this package work outdoors in direct sunlight?
- The red beam laser is most visible indoors or in low-light conditions. For outdoor use in bright daylight, the included HL760 receiver is essential — it detects the beam at distances up to 2,000 feet in diameter where the beam itself is not visible to the naked eye.
- Is the RC402N remote control included, or is it an optional add-on?
- The RC402N radio remote control is included in this X22 package. It allows one operator to control rotation speed, grade settings, and instrument functions from up to 200 feet away, enabling efficient single-person operation on the jobsite.
- What is the warranty on the Spectra Precision HV302GC?
- Spectra Precision provides a standard manufacturer's warranty on the HV302GC laser. As an authorized dealer, Express Tools ensures all units are sold new with full factory warranty coverage. Contact us for current warranty terms or to initiate a warranty service request.
