Spectra Precision GL722 Dual Grade Laser

When the highest precision is required, the GL722 has unmatched dual grade performance for general leveling, fine grading and screed machine control applications.

For the highest precision in grade work, the Spectra Precision GL722 is the choice.
The GL722 is a fully automatic, dial-in self leveling dual grade laser designed for machine control operation in the fields of roading, civil construction, drainage and general earthworks.
The Spectra Precision GL722 is tested, calibrated and serviced in New Zealand by our Auckland and Christchurch Calibration Service centres, who have a full range of parts and backup.

Compared with the GL422N and GL622N models, the GL722 features a different detection system that is specially designed to work with machine control receivers as well as a long range radio remote control, with an operation range of up to 230 meters.
The GL722 offers automatic features like automatic Grade Match, PlaneLok and Automatic Axis Alignment.
The included CR600 receiver is a combination hand and machine mounted laser receiver, it has the facility to be attached to a machine via magnets.

For applications that require maximum stability and accuracy such as sloping concrete pads, PlaneLok automatically locks the beam on the receiver and keeps it on grade.
