Spectra Precision DG813 Pipe Laser with Dialgrade, RC803 Remote & SF803 Spotfinder

$5,196.00

Overview

The Spectra Precision DG813 Dialgrade Pipe Laser represents the latest generation in laser-guided underground utility construction, combining compact design with advanced beam intelligence. Designed for municipal sewer contractors, water authority crews, and utility installation firms, the DG813 delivers precision grade control in pipes ranging from 8 to 36 inches. The integrated graphic-display Dialgrade technology eliminates manual calculations and setup errors, while the included RC803 wireless remote provides full laser control from the trench—no trips back to adjust settings. Combined with the SF803 Spotfinder receiver for rapid beam acquisition, this complete kit ensures accurate installations whether you're laying storm drains, sanitary sewers, or force mains in challenging underground environments.

Job Applications

Sanitary Sewer Installation: Maintain precise fall rates (typically 1-2%) across long runs to ensure proper flow velocity and prevent settling—the Dialgrade interface lets you dial in exact percentages without conversion charts or calculators.
Storm Drain Systems: Achieve steeper grades for rapid water evacuation while maintaining accuracy in large-diameter concrete pipes—the expanded working range handles jobs up to 1,500 feet between manholes.
Force Main & Pressure Pipe: Set dead-level or minimal-grade installations for pressurized systems where air pockets must be eliminated—the ±10 arc second accuracy ensures proper air release valve placement.
Culvert Replacement: Work in confined spaces where the compact DG813 design fits easily, and the wireless remote eliminates dangerous trips through active traffic zones to make adjustments.
Trenchless Bore Operations: Guide auger boring and pipe jacking projects with continuous grade reference—the IP68 rating withstands mud, groundwater, and demanding underground conditions.
Municipal Utility Rehabilitation: Verify existing grades before rehabilitation and ensure new liner installations match design specifications—the Spotfinder provides quick confirmation without removing equipment.

FAQ

What pipe sizes can the DG813 accommodate?: The DG813 works in pipes from 8 inches to 36 inches in diameter using the included adjustable pipe stand. The stand features spring-loaded extensions that secure the laser firmly against the pipe wall, maintaining stability even in wet conditions. For pipes larger than 36 inches, optional extension accessories are available to expand the range.
How far can I control the laser with the RC803 remote?: The RC803 wireless remote provides reliable control up to 300 feet from the laser, allowing operators to make grade adjustments, power the unit on/off, and check battery status without leaving the work area. This eliminates time-consuming trips back to the laser head and improves safety by keeping workers out of traffic zones and confined spaces.
Can the DG813 be used in wet or flooded pipe conditions?: Yes, the DG813 is rated IP68 for complete dust and water protection, meaning it can withstand submersion and operate reliably in wet trenches, flooded pipe sections, and muddy conditions typical of underground utility work. The sealed housing protects internal electronics while maintaining laser accuracy even when partially submerged.
What's the difference between the DG813 and older Dialgrade models?: The DG813 features an upgraded graphic LCD display with improved visibility in bright conditions, extended battery life (40+ hours vs. 30 hours), enhanced wireless range for the remote control, and lighter weight construction. The accuracy specification remains industry-leading at ±10 arc seconds, but the user interface has been redesigned for faster setup and fewer button presses to change grades.

Why This Equipment

IP67 Waterproof

Fully submersible — rated for trench conditions, rain, and muddy job sites.

Grade Range

Set grades from flat to steep in a single unit — no attachments or recalibration.

Remote Control

Set and adjust grade from the manhole without touching the instrument inside the pipe.

All-Day Battery

Rechargeable Li-Ion with 20+ hour runtime — one charge covers a full shift.

KIT CONTENTS

What's In The Box

Why Buy This?

Grade pipe right the first time. Every time.

String-line setup takes 30–45 minutes per sewer run. A pipe laser sets in under 5 minutes and holds grade all the way to the manhole. That time savings compounds across every run you pull in a day — and every job this year.

The difference between residential-grade and professional pipe lasers isn't just range — it's grade resolution, self-centering targets, and how well the unit holds calibration when it takes a hit inside a trench. On gravity sewer that has to pass inspection, "close enough" is not an option.

Express Tools stocks authorized pipe lasers from the brands contractors trust on municipal and DOT projects. Same-day shipping, genuine factory-fresh units, and technical support if you have questions on setup or calibration.
