Designed for Precision and Performance: The Spectra Precision DG813 Pipe Laser

When it comes to pipe laying, the Spectra Precision DG813 is engineered to deliver unmatched productivity, precision, and ruggedness, especially in demanding underground conditions. Whether you’re working with tight inverts or expansive trenches, the DG813 thrives in environments where reliability is paramount.

Rugged, Reliable, and Ready for Any Challenge

The DG813 is built to withstand the harshest underground conditions, ensuring maximum durability and efficiency. Featuring the latest cutting-edge technology, it moves with incredible speed and pinpoint accuracy for alignment and grade — making it the top choice for professionals worldwide.

Smart Technology for Seamless Operation

The DG813 comes equipped with Smart Spot Finder technology that allows the laser to automatically align to a target, simplifying even the most complex setups. Plus, it calculates the grade, enabling you to quickly check the accuracy of your previous work with ease during a second-day setup.

Extended Range & Effortless Control

With an impressive operational range of 500 feet, the DG813 can cover long stretches of pipe with a single setup between manholes. The included RC803 Remote Control provides full function control, utilizing infra-red for up to 500 feet of control inside pipes, while radio communication extends functionality to 430 feet for over-the-top setups.

User-Friendly Interface for Quick Setup

Say goodbye to the confusion of hidden buttons or complicated controls. The large graphical user interface is easy to read and navigate, even in low light conditions, such as when working inside a manhole. With intuitive, menu-driven controls, the DG813 ensures anyone on your crew can operate it with minimal training, cutting down setup time and boosting productivity.

The RC803 remote control mirrors this simple interface, making remote operation just as straightforward.

Advanced Features for Maximum Productivity

With its Smart Spot Finder SF803, the DG813 enhances productivity by aligning the laser automatically to the center of the Spot Finder, ensuring precise setups right from the first day. The Beam Alignment, Beam Detection, and Grade Calculation functions are exclusive to the Spectra DG813, further streamlining your work.

Brilliant Beam Visibility

The DG813 boasts a bright, fast-moving beam that offers exceptional visibility inside pipes. A unique patented target bends the beam upwards, making it easy to spot from above or inside the trench, eliminating the need for awkward bending.

Versatile Mounting Options

The DG813 is highly versatile, offering multiple attachments that allow it to be mounted in pipes ranging from 6 inches (150mm) upwards. Additionally, the blower accessory evenly circulates air inside the pipe, preventing beam refraction and ensuring consistent, accurate readings.

Maximize Efficiency and Performance

Thanks to its intuitive interface and automatic features, the DG813 significantly improves efficiency, offering unprecedented performance and reliability. Working in the trenches has never been easier with Spectra Precision's latest innovation in pipe lasers.

• Why Contractors Trust the Spectra Precision DG813 Pipe Laser

  • Compact Build, Big Advantage
    The reduced length design allows for quick and easy setup — even in tight inverts or confined trench spaces.

  • Self-Leveling Across the Full Grade Range
    With an impressive self-leveling range of -12% to +40%, the DG813 handles everything from flat grades to steep slopes without breaking a sweat.

  • Faster Setups with Cross-Axis Compensation
    No need to level the pipe — just place it in position and the DG813 takes care of the rest. Cross-axis compensation ensures faster, more accurate setups with less guesswork.

  • Bright, Visible Beam Up to 150m (500ft)
    The highly visible beam provides clear sightlines for long runs, even in bright outdoor conditions or deep trenches.

  • Dual-Mode Remote Control with Extended Reach
    The RC803 remote works via radio (130m / 430ft) or infra-red (150m / 500ft) for full control whether you're working in-pipe, in-trench, or over-the-top.

  • Intuitive Graphical Interface – Laser & Remote
    A large, high-visibility display makes it easy to read and operate from inside or outside the pipe. The same graphical menu appears on the RC803 remote — what you see on the laser is exactly what you see on the controller.

  • Long Runtime with Flexible Power Options
    Includes NiMH rechargeable batteries for up to 40 hours of runtime and alkaline compatibility for up to 50 hours — no external battery pack needed. An optional car charger keeps you powered up on remote job sites.

  Advanced Features That Save Time and Prevent Rework

  • Line-Set/Check – Quickly align to the manhole and establish direction with ease. The beam supports up to 100% grade, perfect for short or steep trench sections.

  • Line Scan – Quickly centers the beam on your target, ideal for second-day setups.

  • Line Alert – Notifies the crew if the laser has been disturbed, preventing costly rework and errors.

  Smarter with the SF803 Spot Finder – Precision You Can Count On

  Pair the DG813 with the SF803 Spot Finder to unlock powerful automatic features:

  • Spot Align – Automatically centers the laser to the Spot Finder or aligns it to the manhole in deep or short trenches, as well as over-the-top setups.

  • Spot Match – Verifies that pipe has been laid on-grade and helps calculate the slope between manholes. Also great for checking existing pipe grades.

  • SpotLok – Locks the beam in a fixed position, ensuring stability when external factors like vibration or movement might cause drift.

  • Spot Search – Helps manually locate the beam over long distances, even when working outside the trench.

• Installation of gravity flow sanitary pipelines
• Storm sewer pipelines
• Pipe jacking
• Tunnel boring
• Can be used in a pipe or in “Over the Top” set-ups
• Steep slope applications at mountain areas
• Installation of solar farms

Industry-Leading Self-Leveling Range

The Spectra DG813 delivers the largest automatic self-leveling range in the industry. No rough leveling, no complicated setup — just place it in the pipe, manhole, or open cut and start working. The DG813 levels itself, saving time and reducing training needs for your crew.

Line Alert – Your Safety Net Against Costly Rework

Working in wet, vibrating, or unstable environments? Line Alert flashes the beam if the laser has been bumped or disturbed — giving you instant feedback and helping you avoid expensive rework. Combined with a self-leveling warning, it ensures you stay accurate, on schedule, and within budget.

Line Set/Check – Setup Without Slowing Down

With Line Set/Check, raise the beam up to 100% above the trench to set your line using an above-ground stake — no need to move excavators or wait for a clear trench. This is a huge time-saver and perfect for pipe jacking operations where the line needs to be rechecked after every push.

Spot Finder SF803 – Makes the DG813 the Smartest Pipe Laser on the Planet

The optional SF803 Spot Finder unlocks exclusive features only available on the DG813:

• Spot Align – Automatically centers the beam to your target

• Spot Match – Check installed grade or measure slope between manholes

• SpotLok – Lock the beam in place, even on steep or unstable grades
  These automated features make the DG813 the most advanced pipe laser in the industry.

Patented Target – See the Beam Without Bending

The patented Target Lens bends the laser beam upward into your natural line of sight, making it easy to see the beam from above — no need to crouch or lean over.
