Spectra Precision GL722IR Dual Grade Laser with RC703 Remote and CR600 Receiver

Overview

The Spectra Precision GL722IR Dual Grade Laser System represents the pinnacle of professional-grade laser leveling technology for contractors who demand precision and versatility on every job site. This complete package combines the industry-leading GL722IR dual-grade laser with the RC703 remote control and CR600 receiver, delivering a turnkey solution for excavation, concrete finishing, grading, and site preparation projects where accuracy isn't negotiable.

What sets the GL722IR apart is its dual-grade capability—seamlessly switching between single-grade and dual-grade (slope) modes to handle everything from simple elevation work to complex drainage systems and parking lot slopes. The laser rotates at variable speeds up to 800 RPM, providing a brilliant 360-degree reference plane visible across job sites up to 2,600 feet in diameter. Built to withstand the punishing conditions of construction environments, this system features IP68-rated dust and water protection, allowing operation in rain, mud, and extreme temperatures from -4°F to 122°F.

The included RC703 remote control puts full laser operation at your fingertips from up to 1,000 feet away, eliminating constant trips back to the laser to make adjustments. The CR600 receiver ensures reliable detection in bright sunlight when the laser beam becomes invisible to the naked eye, extending your working range and productivity throughout the day. For contractors running excavators, dozers, graders, or concrete screeds, this complete system provides the accuracy, durability, and efficiency required to keep projects on grade and on schedule.

Job Applications

• Excavation and Site Grading: The GL722IR's dual-grade capability makes it ideal for establishing complex slopes required for proper site drainage, building pads, and parking lot subgrades. The ability to set precise X and Y axis slopes simultaneously eliminates the need for multiple laser setups, saving hours on large grading projects.
• Concrete Slab Finishing: Whether pouring basement floors, warehouse slabs, or commercial foundations, the laser provides a constant elevation reference for screed operators. The variable rotation speed allows you to optimize beam brightness based on ambient light conditions, while the receiver ensures detection even in bright sunlight streaming through open job sites.
• Drainage and Underground Utilities: Proper slope is critical for gravity-fed drainage systems, sewer lines, and water mains. The GL722IR's ±1/8" grade accuracy at 100 feet ensures pipes and trenches maintain the precise fall required for code compliance and optimal flow, preventing costly callbacks for standing water or inadequate drainage.
• Agricultural Land Leveling: From vineyard preparation to field drainage systems, the GL722IR handles the large working diameters common in agricultural applications. The 2,600-foot working range means fewer setups when grading expansive fields, while the rugged IP68 construction withstands dusty, muddy farm environments.
• Parking Lot and Roadway Construction: Complex drainage planes in parking facilities require precise multi-directional slopes—exactly what dual-grade mode delivers. The remote control allows the grade foreman to fine-tune slopes from the active work area without leaving the screed or grader, maintaining productivity while ensuring accuracy.
• Sports Field and Golf Course Construction: Athletic facilities demand precise grading for proper drainage and playability. The GL722IR's accuracy and dual-grade capability ensure baseball fields, football pitches, and golf greens meet exacting specifications for surface drainage while maintaining the gradual slopes athletes require.

FAQ

What's the difference between single-grade and dual-grade mode?

Single-grade mode creates a sloped plane in one direction only—ideal for simple drainage or pipe work. Dual-grade mode allows you to set slopes on both the X and Y axis simultaneously, creating complex drainage planes required for parking lots, building pads, or any application needing multi-directional slope. The GL722IR handles both modes, giving you maximum versatility.

How far can I operate the RC703 remote control from the laser?

The RC703 remote has an effective range of up to 1,000 feet (300 meters) from the laser in optimal conditions. This allows you to control laser functions, adjust grades, and change rotation speed from your work area without walking back to the laser. Range may be reduced in areas with heavy radio interference or physical obstructions.

Can this laser be used for both interior and exterior applications?

Absolutely. The GL722IR excels in both environments. For interior concrete work, the visible laser beam provides easy reference for screed operators. For exterior excavation and grading, the CR600 receiver detects the laser beam even in bright sunlight when the beam is invisible to the eye, extending your working range to the full 2,600-foot diameter. The IP68 rating means weather won't shut down your work.

How long does the battery last on a single charge?

The rechargeable Li-ion battery provides over 100 hours of continuous operation at moderate rotation speeds—typically several weeks of normal job-site use on a single charge. Runtime varies based on rotation speed (higher speeds consume more power) and temperature (cold weather reduces capacity). The system also accepts alkaline batteries or a 12V adapter for extended remote-site projects.
