Automatic Self-leveling Dual Grade Laser

The automatic, self-leveling Spectra Precision® GL422N dual grade laser is the most rugged, cost-effective laser that does three jobs—level, grade, and vertical alignment. Even in harsh jobsite conditions, the GL422N delivers consistently reliable and accurate performance, enabling you to work faster and smarter.

The rugged GL422N laser can withstand drops of up to one meter (three feet) onto concrete and tripod tip-overs up to 1.5 meters (five feet). This strength, combined with full weatherproofing and dustproofing, reduces downtime and lowers repair costs over the life of the product.

Each GL422N laser system includes the advanced HL760 Digital Readout receiver

Grade Match measures and displays the existing grade over unknown ground. As a consequence, it eliminates time-consuming and error-prone calculations
PlaneLok automatically locks on to an existing horizontal elevation or vertical alignment point which eliminates all drift or possibility of error due to improper calibration or weather.
