Spectra Precision GL710 Single Grade Laser package with HL700 Receiver

Purpose-Built Grade Laser for Earthwork, Drainage, and Civil Construction

The Spectra Precision GL710 is engineered from the ground up for contractors who live and die by grade. Whether you're cutting drainage swales, pitching a parking lot, prepping a building pad, or managing a large excavation site, the GL710 delivers the slope accuracy and range you need to get the job done right the first time. Paired with the HL700 digital receiver, this is a complete, field-ready grading package — not a general-purpose laser with a slope mode bolted on.

Overview and Jobsite Applications

The GL710 operates as a single-slope rotary laser, projecting a grade reference plane at a user-defined pitch across your entire worksite. With a self-leveling range of ±5° and a manual slope range of 0–25%, it handles everything from nearly flat drainage grades to aggressive site cuts. The 2,000-foot diameter operating range (with receiver) means one setup covers most commercial pads and roadway segments without repositioning. IP66-rated sealing protects the instrument against dust and water intrusion, making it a reliable tool on muddy, wet, or dusty jobsites. The HL700 receiver features a large digital display readable in direct sunlight, audible and visual grade indicators, and a wide 12-inch detection window that lets operators work efficiently without line-of-sight precision to the instrument.

Job Applications

Drainage and Stormwater Grading: Set your target slope once and run the entire drainage corridor without rechecking with a hand level. The GL710 holds grade consistently across long runs, reducing rework and compaction re-cuts.

Parking Lot and Flatwork Pitch: Achieve consistent 1–2% cross-slopes across large paving areas. Machine operators and screed crews can reference the HL700 in real time without stopping for grade checks.

Building Pad Preparation: Cut and fill to a precise elevation plane before foundation forming begins. The GL710's accuracy keeps subgrade tolerances tight enough to satisfy most structural specifications.

Road and Infrastructure Excavation: Establish consistent subgrade on road projects. The 2,000-ft operating diameter means you're not repositioning the instrument at every station.

Frequently Asked Questions

Can the GL710 be used for machine control on a motor grader or dozer?

The GL710 is compatible with Spectra machine control receivers such as the HR320, which can be mounted directly to blade masts on motor graders, dozers, and scrapers. For full automated blade control, verify compatibility with your machine control system or contact us for guidance.

What is the difference between the GL710 and the GL722?

The GL710 is a single-slope laser, meaning it projects grade in one axis only. The GL722 is a dual-slope model that can simultaneously set grade in two directions — useful for complex drainage intersections or crowned road sections. For most grading and drainage applications, the GL710 is sufficient and more cost-effective.

How long do the batteries last in the field?

The GL710 runs up to 100 hours on four standard D-cell alkaline batteries. In normal field conditions with moderate rotation speed, most crews get multiple full work weeks before needing to swap batteries, which are available at any hardware store.

Is the GL710 waterproof enough for rainy conditions?

Yes. The GL710 carries an IP66 rating, meaning it is fully protected against dust ingress and powerful water jets from any direction. It is designed to continue operating in rain and wash-down conditions typical on active grading sites.
