Topcon HiPer CR Compact GNSS Receiver Board

The Spectra Precision HV1305C-4-NR is a professional-grade horizontal/vertical red beam rotary laser kit built for contractors who demand precision, versatility, and smart job site technology in a single package. Whether you're establishing level references across a large interior space, shooting plumb lines for wall framing, or setting dual-slope grades for concrete flatwork, the HV1305C delivers the accuracy and workflow efficiency your projects require. This kit includes everything you need to get to work immediately — no additional purchases required.

Overview & Jobsite Applications

The HV1305C-4-NR kit is engineered for interior and exterior applications where a high-visibility red beam paired with smart remote control capability can dramatically improve productivity. With ±10 arc-second accuracy and a working range of up to 1,500 feet in diameter (with receiver), this laser handles everything from suspended ceiling grids and partition walls to floor leveling, site layout, and equipment alignment. The included Spectra smartphone app enables full laser control from up to 200 feet away, eliminating the need to constantly return to the instrument to make adjustments.

Job Site Applications

Suspended Ceiling Installation: Use horizontal mode at full rotation to shoot a consistent reference plane across an entire room, allowing ceiling crews to set hangers and grid components without snapping chalk lines on every wall.

Partition & Stud Wall Framing: Switch to vertical mode to project a true plumb reference line for layout of interior partition walls, door openings, and curtain wall systems with speed and repeatability.

Concrete Flatwork & Floor Leveling: Activate dual-slope mode to simultaneously control grade in two axes — ideal for drainage slopes on warehouse floors, loading docks, and interior concrete pours.

Site Layout & Equipment Alignment: At exterior ranges with the HL760 receiver, establish benchmark elevations across a job site for foundations, footings, and utility trenching without a second person at the instrument.

Frequently Asked Questions

Does the HV1305C-4-NR work outdoors in daylight?

The HV1305C uses a red beam, which is best suited for indoor and low-light outdoor conditions. In bright daylight at extended ranges, you'll want to use the included HL760 digital receiver, which detects the beam reliably in outdoor conditions up to 750 feet in radius regardless of ambient light.

What does the "-NR" suffix mean in the model number?

The "-NR" designation indicates this kit ships without the RC602 dedicated radio remote control. Instead, remote functionality is provided via the Spectra smartphone app over Bluetooth, which offers comparable control range and full instrument adjustment capability from your iOS or Android device.

Can I use the HV1305C for grading and slope work?

Yes. The HV1305C features dual-slope mode, allowing you to set independent grade percentages on both the X and Y axes simultaneously — up to 25% each. This makes it well-suited for drainage slopes, ADA-compliant ramp layouts, and other applications requiring controlled grade in multiple directions.

Is the rechargeable battery pack the only power option?

The included NiMH rechargeable pack is the primary power source, delivering up to 35 hours of runtime. The instrument is also compatible with standard alkaline D-cell batteries via an optional battery holder adapter, giving you a backup option on job sites where charging access is limited.
