The automatic, self-levelling Spectra Precision® GL412N single grade laser is the most rugged, cost-effective lasers that do three jobs—level, grade, and vertical alignment. Even in harsh job site conditions, the GL412N delivers consistently reliable and accurate performance, enabling you to work faster and smarter.

The rugged GL412N laser can withstand drops of up to one metre (three feet) onto concrete and tripod tip-overs up to 1.5 metres (five feet). This strength, combined with full weatherproofing and dust-proofing, reduces downtime and lowers repair costs over the life of the product.

The GL412N 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.
The CR600 receiver is also an option when a machine mounted display elevation is required.
