The Spectra Precision HV302-14 is a professional-grade red rotating laser system engineered for contractors who need reliable horizontal and vertical plane projection in a single instrument. Packaged with the CR700 remote-capable receiver, wireless remote control, and batteries, this kit is ready to deploy straight out of the case for earthwork grading, structural layout, and plumb verification — no additional accessories required on day one.
Built for Mixed-Use Job Sites
Whether you are establishing finished floor elevations on a slab pour, shooting grade across a large excavation, or setting building corners during framing, the HV302-14 delivers the range and accuracy that mixed-use crews demand. Its dual-axis self-leveling design eliminates setup errors common with manual instruments, and the variable scan mode lets operators focus beam intensity on specific work zones to maximize visibility in challenging light conditions. The wireless remote control keeps one operator productive without a second person at the instrument — a real labor saver on solo or small-crew jobs.

Job Site Applications
Excavation and Rough Grading: Set the HV302 on a tripod at the edge of the cut zone and use the CR700 receiver on a grade rod to establish consistent cut and fill targets across the entire excavation — no stringlines required.
Foundation and Slab Layout: Project a vertical plane to transfer building lines from batter boards to footing forms, maintaining squareness and alignment without constant re-measurement from a baseline.
Interior Framing and Ceiling Work: Use horizontal mode to project a level reference line around a room perimeter for drop ceiling grid installation, partition wall top-plate alignment, and MEP rough-in elevations.
Plumb Transfer and Column Setting: Switch to vertical plane mode to plumb-check columns, curtain wall mullions, and rough door or window openings in a single pass, replacing traditional plumb bobs and reducing cycle time.

Frequently Asked Questions
- Can the HV302-14 be used outdoors in direct sunlight?
- Yes. When paired with the included CR700 receiver, the HV302-14 operates effectively outdoors at ranges up to 2,000 ft even in bright sunlight. The receiver detects the beam electronically, so ambient light that limits naked-eye visibility does not affect instrument performance.
- Does this kit include everything needed to start working on day one?
- Yes. The HV302-14 package includes the laser instrument, CR700 receiver, RC703 wireless remote, batteries, and a carrying case. You will need a tripod and grade rod for most elevation and grading tasks, both of which are available separately on our site.
- What is the self-leveling range of the HV302?
- The HV302 self-levels automatically within a ±5° range. If the instrument is set up on terrain or a surface that exceeds this tilt, an out-of-level alarm activates and the laser shuts off to prevent inaccurate readings. Always set up on a reasonably stable, near-level surface.
- Is the HV302 compatible with other Spectra Precision receivers beyond the CR700?
- Yes. The HV302 is compatible with a range of Spectra Precision and Trimble laser receivers, including the HL760. Using an alternative receiver may affect available remote-control functionality, so confirm compatibility with your specific receiver model before substituting.
