Overview
The Spectra Precision DG813-5 Dialgrade Pipe Laser represents the pinnacle of grade control technology for professional pipe laying operations. This complete system combines a precision-engineered laser transmitter with an intuitive graphic display, comprehensive mounting hardware, and remote control capability to deliver unmatched accuracy in sewer, water, and storm drain installations. Built to withstand the punishing environment of underground construction, the DG813-5 features fully waterproof housing rated to IP68 standards, ensuring reliable performance even when submerged. The included large pipe plate, vertical pole mount, wireless remote control, and spot finder target provide everything contractors need for immediate deployment on municipal infrastructure projects, utility installations, and large-scale development work where precise grade establishment is non-negotiable.

Job Applications
- Sanitary Sewer Installation: Maintain precise slopes from 0.50% to 2.00% across extended runs, ensuring proper flow velocities and preventing settling in gravity sewer systems up to 1,500 feet between manholes.
- Storm Drain Construction: Set steep grades up to 40% for inlet connections and outfall structures while maintaining accuracy in large-diameter RCP and HDPE pipe installations where flow capacity depends on exact grade establishment.
- Water Main Placement: Establish minimal grades (0.25% to 0.50%) required for proper drainage during maintenance and air release in potable water transmission lines, with accuracy critical for preventing air pocket formation.
- Culvert and Cross-Drain Work: Project laser reference through highway culverts, driveway crossings, and railroad bores where direct line-of-sight verification is impossible and grade tolerances are tight.
- Microtunneling and Guided Boring: Provide surface reference for underground steering operations, with the remote control allowing grade adjustments without entering the excavation or disrupting boring operations.
- Tunnel Construction: Waterproof design withstands high-humidity tunnel environments while delivering the long-range capability needed for mining, subway, and utility tunnel applications where control points may be hundreds of feet apart.

FAQ
- What's the difference between the DG813 and DG813-5 models?
- The DG813-5 is a complete kit that includes the large pipe plate, vertical pole mount, remote control, and spot finder target. The base DG813 includes only the laser transmitter, battery, and case. The "-5" kit provides everything needed for immediate field deployment without purchasing accessories separately.
- Can this laser be used in flooded trenches or standing water?
- Yes, the DG813-5 carries an IP68 rating, meaning it's completely waterproof and submersible to depths of 16 feet. The laser will continue operating normally even when partially or fully submerged, making it ideal for dewatering challenges common in utility construction. Always ensure the battery compartment seal is properly seated before water exposure.
- How do I set a grade like 0.75% using the Dialgrade display?
- The graphic Dialgrade display allows direct grade entry in 0.01% increments. Simply use the control panel or remote to input "0.75" and the laser automatically adjusts to that exact slope. The display confirms your setting and shows whether you're in positive (downhill) or negative (uphill) grade mode. No conversion calculations or grade sticks required.
- What's the maximum distance I can use this laser effectively?
- Visible range depends on ambient light conditions. In underground or shaded conditions, the beam is visible to the naked eye up to 200 feet. Using the included spot finder target extends range to 500 feet, and when paired with an electronic receiver like the CR700 (sold separately), you can achieve accurate grade control at distances up to 1,500 feet.
