Overview
The Spectra Precision HV302 Horizontal/Vertical RED Laser is the industry standard for general-purpose construction applications that demand precision across both interior finishes and exterior site layout. This dual-plane red laser system projects vertical and horizontal beams simultaneously, eliminating the need for multiple setups and cutting your layout time in half.
Built for the demands of active jobsites, the HV302 delivers ±1/8" accuracy at 100 feet with visible red beams that are easy to see in most lighting conditions. The included HL760 Receiver extends your working range to 2,600 feet diameter, making this package ideal for commercial construction, site preparation, and large-scale layout work where long-distance referencing is critical.
This complete package includes the HL760 digital laser receiver with LCD readout, RC602 remote control for line selection up to 300 feet away, and the rugged carrying case that protects your investment between jobs. Whether you're establishing building lines, setting grade stakes, or installing drop ceilings, the HV302 gives you the versatility to handle multiple applications with a single tool.

Job Applications
- Commercial Foundation and Slab Layout: Project horizontal and vertical reference lines simultaneously to establish building corners, column locations, and wall lines without constantly repositioning your laser. The dual-plane capability means you can square up foundations and check plumb in a single setup, saving hours on large concrete pours.
- Site Grading and Excavation: The 2,600-foot diameter range with the HL760 receiver makes the HV302 ideal for establishing grade elevations across large sites. Mount the receiver on your grade rod or excavator stick to achieve precise depth control for footings, utilities, and drainage systems without needing multiple benchmark setups.
- Interior Wall Framing and Partition Layout: Use the visible red vertical beam to establish plumb lines for metal stud layout, ensuring walls are perfectly straight over long runs. The horizontal beam simultaneously provides a level reference for header heights and door openings, keeping your framing crew moving efficiently without stopping to check individual locations.
- Ceiling Grid and Soffit Installation: The horizontal beam creates a consistent elevation reference around the entire room perimeter for drop ceiling systems and drywall soffits. Because the beam is visible up to 300 feet indoors, one setup typically covers an entire floor, eliminating the time wasted on chalk lines that sag or multiple laser moves.
- Concrete Formwork and Elevation Control: Set your deck elevations, curb heights, and wall forms to the horizontal beam while using the vertical plane to check formwork alignment. The RC602 remote lets you switch between horizontal-only, vertical-only, or dual-plane modes from across the jobsite, so you're not walking back and forth to the laser every time you change tasks.
- Electrical and Mechanical Rough-In: Establish consistent mounting heights for electrical boxes, conduit runs, and HVAC penetrations using the horizontal beam as your reference. The vertical beam helps align equipment rooms, panel boards, and vertical conduit runs to maintain professional-looking installations that pass inspection the first time.

FAQ
- What's the difference between using this with and without the receiver?
- Without the receiver, you're limited to the visible red beam range of approximately 300 feet indoors and less outdoors depending on lighting conditions. The HL760 receiver detects the laser beam even when it's not visible to the eye, extending your working range to 2,600 feet diameter. For interior work under 200 feet, you'll often work with just the visible beam. For site work, excavation, or long-distance layout, the receiver is essential. The receiver also provides precise digital readout showing exactly how far above or below grade you are, which is critical for elevation work.
- Can I see the red beam in full sunlight for outdoor applications?
- Red lasers are visible in moderate outdoor lighting conditions, but become difficult to see in direct bright sunlight beyond 50-75 feet. For outdoor site work, you'll rely on the HL760 receiver which detects the beam regardless of ambient light. If you regularly work in bright outdoor conditions and need to see the beam without a receiver, consider a green laser model which is 4x more visible to the human eye. That said, the red beam of the HV302 works perfectly for most construction applications where you're using the receiver for precision work anyway.
- How does the remote control work and what's the range?
- The RC602 remote control operates up to 300 feet from the laser and allows you to select which beam(s) to display: horizontal only, vertical only, or both planes simultaneously. This is valuable when you need different configurations throughout the day—you can switch modes from wherever you're working without walking back to the laser. The remote also lets you enable scan mode (sweeping beam for specific layout tasks) and includes slope-matching capability. It uses a standard coin-cell battery and clips to your belt or tool pouch.
- What's the battery life and can I run this all day without recharging?
- The included rechargeable NiMH battery pack provides 40+ hours of runtime in dual-plane mode, which translates to a full work week on a single charge for most applications. If you run only one plane (horizontal or vertical), battery life extends even further. You can also run the HV302 on 4 D-cell alkaline batteries as a backup option, which is useful for remote jobsites where charging isn't convenient. Many contractors keep a second NiMH battery pack charged and ready to swap mid-day on jobs where the laser runs continuously for layout checking.
