The Spectra Precision HV1305C-SC-2A is a professional-grade dual-slope rotary laser system engineered for contractors who need precise grade control across a wide range of interior and exterior applications. This fully loaded package arrives jobsite-ready with everything you need to start working: the HV1305C laser, HL760 laserometer receiver, remote control, grade rod, and tripod. Whether you're finishing concrete slabs, cutting site drainage grades, or hanging drop ceilings, the HV1305C-SC-2A delivers the accuracy and versatility that keeps projects on schedule.
Overview: Built for the Demands of Professional Contractors
The HV1305C operates as a true horizontal/vertical rotary laser with independent dual-axis slope capability, allowing you to dial in precise grade percentages on both the X and Y axes simultaneously. The red beam spins at selectable rotation speeds to optimize visibility and detection range depending on site conditions. With a working radius of up to 600 meters (diameter) with the included HL760 receiver, this unit handles large commercial pours, grading layouts, and structural plumb work with ease. The rugged, self-leveling design compensates for minor setup inconsistencies and alerts you when the unit is out of level — a critical safety feature on active jobsites.

Job Applications
Concrete Slab Pours & Footer Work: Set dual-axis slopes to match engineered drainage plans and maintain consistent grade across large pour areas without repositioning the instrument. The HL760 receiver clamps to the screed or rod for hands-free grade checking.
Site Grading & Earthwork: The 600m working diameter and remote control let operators manage machine guidance and grade verification from the cab or ground level, significantly reducing layout crew time on cut-and-fill operations.
Interior Drop Ceiling Layout: Switch to horizontal rotation mode and set a reference plane across an entire floor. Consistent ceiling heights across large commercial interiors are established quickly with a single instrument setup.
Structural Plumb & Vertical Alignment: Engage vertical plane mode for column layout, curtain wall alignment, and wall plumb verification — all from the same unit without swapping instruments.

Frequently Asked Questions
- Can the HV1305C-SC-2A be used outdoors in direct sunlight?
- The HV1305C uses a red beam laser, which is best suited for shaded or overcast outdoor conditions. In bright sunlight, the included HL760 receiver is required to detect the beam at extended ranges. For full outdoor visibility without a receiver, consider a green beam rotary laser.
- What does "dual-slope" mean and why does it matter on the jobsite?
- Dual-slope means the laser can be independently tilted on both the X and Y axes simultaneously. This is essential for applications like parking lot drainage, ADA ramp layouts, and agricultural grading where a single-axis slope would not match the engineered grade plan.
- Is the RC603 remote control included in this package?
- Yes. The SC-2A kit designation confirms inclusion of the RC603 wireless remote, the HL760 receiver, grade rod, and tripod. All components arrive in a single package ready for immediate use.
- What is the warranty on the Spectra Precision HV1305C?
- Spectra Precision backs the HV1305C with a standard limited warranty. As an authorized dealer, Express Tools ensures your unit is fully factory-registered. Contact our team for specific warranty term details or to initiate a warranty service request.
