# Spectra Precision DG711-3 Pipe Laser with RC502 Remote and Large Diameter Pipe Invert
```html
Overview
The Spectra Precision DG711-3 is a professional-grade pipe laser system engineered for large diameter utility installations. This complete package combines the precision DG711 dual grade laser platform with the 1230 Large Pipe Invert, specifically designed for pipe diameters 12 inches and larger. The integrated RC502 remote control provides instant grade adjustments from up to 1,000 feet away, eliminating the need to return to the laser between joint installations. Whether you're laying sewer, storm drainage, or irrigation mainlines, this system delivers the accuracy and efficiency required for municipal and commercial utility projects where grade tolerance is critical and downtime is costly.

Job Applications
- Municipal Sewer Main Installation: The 1230 invert provides exceptional stability in 18"-48" trunk sewer lines where laser movement causes expensive rework and the RC502 remote saves hours of walking in deep, hazardous trenches.
- Storm Drainage Systems: Large diameter storm pipes demand precise grade to prevent standing water and sediment buildup—the DG711-3's ±1/16" accuracy at 100 feet ensures proper flow even on minimal grades of 0.5% or less.
- Commercial Irrigation Mainlines: Golf courses, parks, and agricultural projects require long runs of large-diameter supply pipe where the 1,000-foot remote range eliminates constant trips back to adjust grade between stations.
- Industrial Process Piping: Manufacturing facilities and treatment plants need gravity flow systems where the dual grade capability allows quick adjustments for unexpected site conditions without resetting the entire laser.
- Culvert and Creek Crossing Projects: The IP68 waterproof rating and large pipe invert stability make this system ideal for wet conditions where standard lasers fail and repositioning equipment wastes billable hours.
- Highway Underdrain Installation: DOT projects with strict grade specifications benefit from the DG711-3's precision and the remote control's ability to make micro-adjustments that satisfy inspector requirements without delays.

FAQ
- Can the DG711-3 be used with smaller diameter pipes if needed?
- Yes, while the included 1230 invert is designed for 12"+ pipes, you can purchase the 1231 Medium Diameter Invert separately to accommodate 8"-30" pipes. The DG711 laser platform is compatible with multiple invert sizes, making this a versatile investment. Many contractors keep both inverts on hand to handle varying project requirements with a single laser.
- How does the RC502 remote control improve productivity on large pipe projects?
- The RC502 eliminates the need to walk back to the laser for grade adjustments between pipe joints. On deep trench projects with 12"-48" pipe, this can save 15-30 minutes per adjustment—potentially hours per day. The remote works up to 1,000 feet away and allows you to make precise grade changes, check battery status, and verify settings without climbing in and out of the trench, significantly improving safety and efficiency.
- What's the difference between the DG711-3 and standard pipe laser packages?
- The DG711-3 specifically includes the 1230 Large Diameter Pipe Invert designed for stability in 12"+ pipes, whereas standard packages typically include smaller inverts suited for 6"-12" pipe. The larger invert provides a wider, more stable platform that prevents laser movement in big pipe—critical for maintaining accuracy over long runs. This package also includes the RC502 remote, which is often sold separately with other configurations.
- Is the DG711-3 system durable enough for demanding municipal construction environments?
- Absolutely. The DG711 has an IP68 rating, meaning it's fully waterproof and can withstand submersion and dusty conditions common on utility projects. The rugged construction is built for daily jobsite use, and the 3-year warranty reflects Spectra's confidence in long-term durability. Contractors regularly use these systems in wet trenches, muddy conditions, and extreme temperatures without performance issues. The included heavy-duty case provides additional protection during transport between jobs.
