Overview

The Spectra Precision DG711 Pipe Laser Standard Package delivers professional-grade accuracy for gravity-flow pipeline installation with dual power flexibility. Built on the proven DG511 platform, this system upgrades your crew with enhanced RC502 remote capability and dual battery options—NiMH rechargeable and alkaline backup. Whether you're setting 500 feet of storm drain or running multi-day sewer mains, the DG711 adapts to your project timeline and power availability. The included NiMH rechargeable battery pack reduces operating costs on extended jobs, while the alkaline option provides instant backup without waiting for recharges. Accurate to ±10 arc seconds, this laser maintains grade over distances up to 1,000 feet with the precision municipal inspectors demand.

Key Specifications

  • Accuracy: ±10 arc seconds (±0.8 mm at 30 m)

  • Grade Range: -10% to +40% in all four directions
  • Self-Leveling Range: ±5° in all directions
  • Battery Runtime: Up to 40 hours (NiMH), 30 hours (alkaline)
  • Remote Control: RC502 with 500-foot range
  • Beam Type: Single red visible laser diode
  • Operating Temperature: -4°F to 122°F (-20°C to 50°C)
  • Protection Rating: IP68 (dust-tight, submersible)
  • Pipe Diameter Compatibility: 8" to 72" with optional adapters

What's in the Kit

  • DG711 pipe laser with self-leveling head
  • RC502 remote control with 500' operating range
  • NiMH rechargeable battery pack with charger
  • Alkaline battery holder (batteries not included)
  • Standard laser target/detector
  • Hard-shell carrying case with foam insert
  • Operator manual and quick-start guide
  • Calibration certificate

Job Applications

  • Storm Drain Installation: Maintain precise 2% minimum grade over hundreds of feet to ensure proper water flow and prevent standing water that leads to maintenance issues.
  • Sanitary Sewer Lines: Hit exact grade specifications for gravity-flow sewers where even 0.1% deviation can cause backups or require costly pump stations down the line.
  • Culvert Placement: Set drainage culverts under roadways and embankments with accuracy that survives inspection and prevents future erosion problems.
  • Agricultural Drainage Tile: Establish consistent grades for field tile systems where water must move efficiently across flat terrain with minimal slope.
  • Industrial Process Piping: Install gravity-fed process lines in plants and facilities where material flow depends on precise elevation control.
  • Force Main Alignment: Set horizontal and vertical alignment for pressurized sewer lines before excavation to minimize conflicts with existing utilities.

FAQ

How long does the NiMH battery pack take to fully charge?
The included charger fully charges the NiMH battery pack in approximately 4-5 hours. A partial charge to 80% capacity takes about 3 hours, which is sufficient for most single-day pours. The charger features LED indicators showing charge status, and you can swap to the alkaline battery holder for immediate operation while the NiMH pack charges overnight.
Can I use this laser in pipes smaller than 12 inches?
Yes, with the appropriate pipe adapter. The DG711 works in pipes from 8" to 72" diameter. For 8"-10" pipes, you'll need the small-diameter adapter kit. The laser housing fits 12" and larger pipes with standard adapters. Keep in mind that in smaller pipes, you'll have less room for the target and may need to work in shorter sections depending on visibility and access.
What's the difference between the DG711 and DG511?
The DG711 includes the upgraded RC502 remote control (versus RC501 on the DG511) with extended 500-foot range and improved button layout. More importantly, the DG711 Standard Package ships with both NiMH rechargeable and alkaline battery options, while the DG511 typically includes only alkaline. The laser head accuracy and leveling mechanisms are identical between models.
Does this laser automatically shut off if it gets bumped out of level?
Yes. If the DG711 is knocked beyond its ±5° self-leveling range, the laser beam shuts off and an alarm sounds to alert your crew. This prevents you from setting pipe to incorrect grade. Once you reposition the laser within its leveling range, it automatically re-levels and the beam resumes. This safety feature has saved countless contractors from expensive re-work on gravity-flow installations.
