Class 2 Laser and <3.4mW (less than 3.4 Milliwatts)

The automatic self-leveling Spectra Precision GL412N single grade and GL422N dual grade lasers are the most rugged, cost-effective lasers that do three jobs—level, grade, and vertical alignment. Even in harsh jobsite conditions, the GL412N/GL422N deliver consistently reliable and accurate performance, enabling you to work faster and smarter. The rugged GL412N/GL422N lasers can withstand drops of up to 1 meter (3 feet) onto concrete and tripod tipovers up to 1.5 meters (5 feet). This strength, combined with full weatherproofing and dustproofing, 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. The receiver provides automatic Grade Match which allows measurement of unknown grade values between two points over unknown ground and eliminates time consuming slope calculations. PlaneLok automatically locks on to an existing elevation or vertical alignment point which eliminates all drift or possibility of error due to improper calibration or weather. The new unique “Fingerprint” function only accepts the beam from the laser it is paired with. The CR600 receiver is also an option when a machine mounted display elevation is required.
