The Spectra Precision® Laser GL512 single grade and GL522 dual grade transmitters are rugged, cost-effective, automatic self-leveling lasers that do three jobs--level, grade, and vertical alignment. Both the GL512 and GL522 include a 2-way, full-function radio remote control with a built-in back-lit grade display. You can do everything with the remote control that you can do at the laser keypad, up to 100 m (330 ft) away from the laser--even from the cab of a machine!
The ability to make grade changes from anywhere on the job greatly reduces setup time and speeds operation. Verbal and visual communication errors are eliminated.
New wireless communication between the HL750 Laserometer and the transmitters provide automatic Grade Matching. Grade Matching allows measurement of unknown grade values between two points. PlaneLok is also available in both the horizontal and vertical planes. PlaneLok automatically locks the beam on the receiver and keeps it on grade. This eliminates all environmental factors that may induce an error. The GL512 and GL522 Grade Lasers self-plumb in the vertical position to allow an even wider range of applications such as anchor bolt installation, tilt up, and curtain wall plumbing.
