Overview
The Spectra Precision DG711-5 Pipe Laser with Vertical Pole Assembly delivers unmatched versatility for complex utility and drainage projects requiring multiple elevation setups. This comprehensive kit combines the proven DG711 dual-grade pipe laser with both the 1230 large-diameter invert assembly and the 1239 vertical pole mount, giving contractors the flexibility to work seamlessly across sewer lines, storm drains, drop connections, and vertical shafts without additional equipment purchases. The dual-grade capability allows simultaneous line and grade reference, while the included mounting options eliminate downtime when transitioning between horizontal pipe runs and vertical alignment work. Ideal for municipal contractors, utility installers, and civil construction teams managing projects with varying pipe diameters and elevation challenges.

Job Applications
- Large-Diameter Sewer Installation: The 1230 invert assembly accommodates 12-48 inch diameter concrete and corrugated pipe, eliminating the need for custom cradles on municipal trunk lines where precise grade control prevents settlement issues and costly rework.
- Drop Manhole Connections: Switch between the horizontal invert and vertical pole assembly to accurately align drop pipes and lateral connections at varying elevations, ensuring proper flow dynamics and compliance with engineering specifications without repositioning equipment.
- Storm Drain Projects with Elevation Changes: The dual mounting options let crews maintain continuous laser reference when transitioning from horizontal pipe runs to vertical shaft alignment, reducing setup time on projects with multiple elevation tie-ins and complex drainage networks.
- Rehabilitation and Lining Work: Use the vertical pole assembly to establish centerline reference inside existing manholes and structures during CIPP lining or rehabilitation projects, where traditional invert mounts cannot be placed due to flow or access constraints.
- Pump Station and Wet Well Construction: The vertical pole configuration provides accurate elevation control for forming work, pipe penetrations, and equipment placement in deep excavations where conventional leveling methods are impractical and precision directly impacts pump performance.
- Bridge and Culvert Drainage Systems: Deploy the laser in both horizontal and vertical orientations to align complex drainage structures, scupper drains, and relief pipes where multiple reference planes are required and survey-grade accuracy prevents hydraulic failures.

FAQ
- Can I use the DG711-5 in pipes smaller than 12 inches with the included assemblies?
- The included 1230 invert assembly is designed for 12-48 inch pipes. For smaller diameters (8-15 inches), you'll need the optional 1232 pipe target assembly, which is sold separately. The vertical pole assembly works independently of pipe size when mounted in manholes or on stable surfaces.
- How quickly can I switch between the invert and vertical pole assemblies on site?
- Switching between mounting configurations typically takes 2-3 minutes once you're familiar with the process. Both assemblies use quick-release mechanisms, and the laser unit transfers between them without recalibration. Keep both mounts accessible in the carrying case for projects requiring frequent transitions between horizontal and vertical setups.
- What's the advantage of dual-grade capability on this model?
- Dual-grade mode projects two independent laser beams—one for line reference and one for grade—allowing your crew to simultaneously check pipe alignment and elevation without repositioning. This is particularly valuable in large-diameter installations where both horizontal and vertical positioning must be verified independently, cutting measurement time nearly in half on complex runs.
- Is the DG711-5 suitable for use in active flow conditions or wet environments?
- Yes, the IP68 rating means the laser can withstand submersion up to 3 feet and handles moisture, mud, and debris common in utility trenches. However, for active flow situations, ensure the mounting assembly is secured properly and consider using the vertical pole setup above the flow line. The rechargeable battery is sealed within the waterproof housing for reliable operation in wet conditions.
