Advanced, High Accuracy Dual Grade Laser
The Spectra Precision GL722 dual grade laser is one of the most advanced grade lasers on the market. The long range operation, advanced radio remote, grade matching, Planelok and Automatic Axis Alignment features mean that you can do quick but highly accurate set-ups for any grade application. With the GL722’s powerful, long range remote control, it takes one person to accurately set up and operate the grade laser. Even grade reverse is done in an instant. You can automatically control all the transmitter’s functions using the remote, even while sitting in the cab of your machine. Grades can be changed on the fly up to 225m (750ft) from the transmitter.
With a grade range of ±10% in the X-axis and -0.5 to +25% in the Y-axis, combined with a 900m (3,000 feet) operating range, no job is too small for this laser.
Automatic Axis Alignment can be done up to 150m (500ft) from the transmitter, providing accurate set-up and eliminating the need to climb a ladder to try and align the laser to your grade hub.
