Spectra Precision HV302G-7 Green Beam Rotary Laser Package
The Spectra Precision HV302G-7 is a professional-grade green beam rotary laser package built for contractors who demand visibility, accuracy, and reliability across a wide range of jobsite conditions. Combining the HV302G green laser unit with the HL760U dual-sided receiver, this package is engineered for interior finish work, mechanical and electrical installation, drywall layout, and exterior grading and site work. Green laser technology produces a beam that is significantly more visible to the human eye than traditional red beam systems, making it the preferred choice for well-lit interior environments and covered exterior applications. Whether you are a drywall contractor, general contractor, MEP installer, or site supervisor, the HV302G-7 delivers the precision and range you need to get the job done right the first time.
Product Overview and Jobsite Applications
The HV302G-7 package is designed around real-world contractor workflows. The rotary laser head projects a full 360-degree horizontal reference plane across the entire work area, eliminating the need for multiple setups and allowing multiple crew members to reference the same level plane simultaneously. The HL760U receiver extends the working range beyond what the naked eye can detect, enabling outdoor use and long-distance layout in large open spaces. The system self-levels within its compensation range and alerts the operator if it is set up outside that range, protecting measurement accuracy on uneven ground. From hanging suspended ceilings and plumb-aligning partitions to establishing finish floor elevations and grading drainage slopes, the HV302G-7 is a versatile workhorse on commercial and residential jobsites alike.

Job Application Examples
Drywall and Partition Layout: Use the HV302G-7 to establish a continuous level reference around the perimeter of a room for track installation, dropped soffit layout, and partition plumb alignment. The green beam remains clearly visible against drywall and concrete block, reducing the need for chalk lines and re-marking.
Suspended Ceiling Installation: Set the laser at finished ceiling height and let the 360-degree plane reference every hanger wire, main tee, and wall angle in the space. The HL760U receiver allows workers on opposite ends of a large commercial bay to verify elevation without walking back to the laser.
Mechanical, Electrical, and Plumbing Rough-In: MEP contractors use the HV302G-7 to coordinate overhead rough-in elevations across trades, ensuring ductwork, conduit runs, and piping maintain consistent clearance from the structural deck and from each other.
Exterior Grading and Drainage: On site work, activate manual grade mode to project a sloped reference plane for swales, parking lot drainage, and landscape grading. Pair with the HL760U receiver on a grade rod for one-person operation across large open areas.

Frequently Asked Questions
- What is the working range of the HV302G-7 with the HL760U receiver?
- With the HL760U dual-sided receiver, the HV302G-7 has a working range of up to 2,000 feet in diameter, making it suitable for large commercial interiors and open exterior grading sites. Without the receiver, the green beam is visible to the naked eye up to approximately 130 feet in bright light conditions.
- Can the HV302G-7 be used outdoors?
- Yes. The HV302G-7 is rated IP55 for dust and water resistance and is designed for both interior and exterior use. For outdoor applications in bright sunlight, the HL760U receiver is essential for detecting the beam beyond short distances. The unit operates reliably in temperatures from -4°F to 131°F.
- Does the HV302G-7 support grade or slope applications?
- Yes. The HV302G-7 includes a manual grade mode that allows the operator to tilt the laser head to project a sloped reference plane. This is useful for site drainage, ramp layout, and applications requiring a consistent slope reference over a large area.
- Is the HV302G-7 compatible with Spectra machine control receivers?
- The HV302G-7 is primarily designed for layout and leveling applications with the included HL760U receiver. For machine control or grade control on earthmoving equipment, a dedicated machine control laser system would be required.
