Versatile Automatic Grade Lasers for Level, Grade and Vertical Alignment
An Excavator’s Dream Package − a grade laser, magnetic machine mounted display receiver, tripod and grade rod in one convenient kit.
The automatic, self-leveling Spectra Precision® GL412-14N single 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 delivers 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 that provides automatic Grade Match - measures and displays the existing grade over unknown ground and eliminates time consuming and error prone calculations, and 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, and the unique "Fingerprint" function - receiver only accepts the beam from the laser it is paired with.
2-Way full fuction remote control allows grade changes to be made from anywhere on the job-site and has mask mode to eliminate interference from other crews running lasers on the job-site.
Spectra Laser Receiver Model No. CR700
The CR700 can be either rod or machine mounted, making it ideal for a wide range of applications. Using the magnetic mount, the CR700 receiver is easily moved between backhoes, small excavators, box blades or skid steer loaders.
The CR700 uses the patented “light bar” technology incorporated in the HL family of Spectra Precision laser receivers. This unique technology provides more accurate and more consistent readings than traditional methods and has fewer electronic components resulting in the most rugged and reliable laser receivers available.
