The Spectra GL722 is a self-leveling construction laser with dual grade capability, automatic axis alignment, grade matching, PlaneLok, and full radio remote functions. With an operating range of up to 3,000 feet, the GL722 also includes a CR600 laser receiver and remote control. With the same range and base capabilities as the Spectra GL720, the GL722 laser level has an X-axis grade range of +/-10 % and -0.5% to +25% in the Y-axis. Grade match allows you to automatically match and display an existing grade, while PlaneLok virtually eliminates beam drift by locking the laser beam to a fixed elevation for increased stability and accuracy.
Automatic axis alignment enables construction professionals to align the GL722 to within +/-40° of the desired axis to easily perform axis alignments in general construction, site preparation, road construction, and machine control. You can also mount this device vertically or horizontally on a 5/8-11 tripod. The included CR600 laser receiver can be used as a handheld or rod mounted laser receiver for a wide range of applications, such as measuring cut and fill, leveling forms and footers, setting grade and measuring elevation changes. It can also be used for machine control with the magnetic mount for use on a backhoe, small excavator, box blade or skid steer loader.
The GL722 laser level offers automatic temperature compensation for accuracy within environmental changes. With two-way communication between the Spectra GL722 laser and its remote control, you can now change the grade and read measurement information from afar. It also features grade bump for raising or lowering the grade remotely and grade reverse that mirrors the grade setting with the push of a button. With fully sealed aluminum housing and protective lens hood, the GL722 allows you to work in all weather conditions. This grade slope laser uses NiMH batteries and offers flexible power options, battery life indicator, and a wirelessly operated sleep mode that saves power.
