Spectra Precision GL422N Dual Slope Laser

The automatic, self-leveling Spectra Precision® GL422N dual grade lasers is the most rugged, cost-effective lasers that do 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 lasers can withstand drops of up to one meter (three feet) onto concrete and tripod tip-overs up to 1.5 m (5 ft). This strength, combined with full weatherproofing and dust-proofing, reduces downtime and lowers repair costs over the life of the product. Each GL412N and GL422N laser system now includes the advanced HL760 Digital Readout (DRO) receiver that provides automatic Grade Match, PlaneLok and Fingerprint function. 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. The unique “Fingerprint” function only accepts the beam from the laser it is paired with.
