Your cart is empty.The automatic self-leveling Spectra Precision GL412N single grade is 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 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.

Warning this laser doesn’t start up on 00.000% slope every time you turn it on (like every other one I have had over the past 30 years) so if you turn it off Friday on 1.5% like we did and Change jobs Monday and start it up it goes back to 1.5% not 0 % like all the other rotary laser I have, and go to work and don’t check the display like we did and do a footing with 4000 dollars worth of concrete in it and 12” of slope ( and no we couldn’t see it there were so many step downs and corners, piers ) then your screwed and will have to demo and redo !! I figure a 8000$ mistake! Really like the receiver most of the time it has a lot of features I wish it didn’t have , seems that if you press the wrong button it gets in a mode that makes it difficult to just keep grade ..maybe it’s to high tech for me .. I will say that when it is set right and in the right mode it is very good .
