The Go-To Dual-Axis Laser for Commercial Construction and Site Work
The Spectra Precision HV1305C-18E is a professional-grade horizontal and vertical laser level system built for contractors who need reliable reference planes on demanding jobsites. Whether you're setting grade on a concrete slab, plumbing interior walls, or laying out structural columns, this self-leveling dual-axis laser delivers the accuracy and working range to keep your crew moving. This complete 18E package includes everything you need to be productive from the moment you arrive on site—no sourcing accessories separately, no delays.
System Overview and Jobsite Applications
The HV1305C-18E combines a powerful red-beam laser with Spectra's proven automatic self-leveling technology to produce a full 360-degree horizontal plane and a precise vertical reference plane simultaneously. Operating in both interior and exterior environments, the laser pairs with the included CR700 multi-use receiver to extend working range up to 2,000 feet in diameter under bright outdoor conditions. The RC1402N remote control lets a single operator manage the instrument from anywhere on the job—eliminating the need for a second person at the tripod. The rugged, IP66-rated housing stands up to dust, moisture, and the general punishment of an active construction site.

Job Applications
Concrete Formwork and Slab Layout: Use the horizontal plane with the CR700 receiver and GR151 rod to set consistent grade elevations across large pour areas. The 2,000-foot working diameter covers even the largest commercial slabs without repositioning the instrument.
Interior Framing and Partition Layout: Switch to the vertical plane to plumb walls, align door and window openings, and transfer reference points from floor to ceiling. The 600 RPM rotation speed produces a clear, continuous visible line for fast layout work indoors.
Site Development and Grading: Mount the laser on the elevator tripod, dial in your benchmark elevation, and use the tenths rod to verify cut and fill operations across the site. Single-operator remote control keeps the workflow moving without a helper at the gun.
Mechanical, Electrical, and Plumbing Rough-In: Establish level reference lines for suspended ceilings, conduit runs, ductwork hangers, and pipe slopes. The compact instrument head fits in tight mechanical rooms and can be repositioned quickly between floors.

Frequently Asked Questions
- Can the HV1305C-18E be used outdoors in direct sunlight?
- Yes. The included CR700 laser receiver is designed specifically for outdoor use and can detect the laser signal in bright ambient light conditions up to 1,000 feet in radius (2,000-foot diameter). Without the receiver, the red beam is best suited for interior or shaded conditions.
- Does this laser self-level automatically, and what happens if it's out of level?
- The HV1305C uses automatic self-leveling within a ±5° range. If the instrument is set up on a surface outside that range, the laser will stop rotating and an audible or visual out-of-level alert will activate, preventing inaccurate readings from being used on the job.
- What is the range of the RC1402N remote control included in this package?
- The RC1402N operates wirelessly up to approximately 330 feet (100 meters) from the instrument. It allows a single operator to power the laser on or off, adjust rotation speed, and switch between horizontal and vertical modes without walking back to the tripod.
- Is the HV1305C-18E compatible with other Spectra receivers or grade rods?
- Yes. The HV1305C is compatible with a range of Spectra Precision laser receivers, including the CR600 and HL760 models. The GR151 grade rod included in this package uses standard tenths graduation and is compatible with any rod clamp or receiver bracket designed for fiberglass rods.
