The new HL760 Digital Readout (DRO) Receiver includes all the functions of the HL750 but adds a new “Fingerprint” feature. Once paired with the laser, the “Fingerprint” function of the HL760 only accepts the beam from the laser it is paired with, reducing errors and conflict between teams working in close proximity with other lasers. The HL760 provides grade matching and PlaneLok capabilities with all the new lasers. In addition, the HL760 can communicate with another HL760 for long-range wireless remote display and monitoring.

The Spectra Precision GL422N dual-grade laser offers all the advantages of its predecessors including long range, high accuracy operation.

Each Spectra Precision GL422N laser system now includes the advanced HL760 Digital Readout (DRO) receiver that provides a digital readout of elevation and can be used at an operating diameter of up to 2,600 ft (800 m).  The CR600 receiver is also an option when a machine mounted display elevation is required.

When used with the Spectra Precision HL760 receiver, several advanced features can be utilized:

Grade Match: Wireless communication between the HL760 receiver and the transmitters provide automatic Grade Match which connects different elevations and will actually calculate and display grade values between two points when using the GL422N.
PlaneLok: For applications that require maximum stability and accuracy is available on the horizontal Y-axis and in both vertical planes. PlaneLok automatically locks the beam on the DRO receiver and keeps it on-grade, reducing typical environmental factors that may induce an error. PlaneLok for vertical alignments provides quick, accurate set-up and easy control. Also provides the ability to quickly set up a vertical plumb or slope reference.

GL412N features and benefits:

• Spectra Precision GL422N is dual grade plus horizontal and vertical. Simple, accurate dial in grade from -10% to +15%.
• Up to 2,600 ft (800 m) working diameter which increases productivity by reducing need for multiple set-ups on a large job site
• Fully automatic self-leveling in both grade axis, horizontal, and vertical which provides fast, accurate setup in all applications
• RC402N radio remote control allows control of all laser functions from up to 330feet (or 100 meters
• Highly rugged design and patented lighthouse seal protects the rotor head and glass and offers superior drop and weather protection for reduced downtime
• 2-way full function remote control allows grade changes to be made from anywhere on the jobsite
• Temperature calibrated for high accuracy over wide temperature changes 
• IP66 dust- and water-proof to withstand harsh jobsite conditions
• Customizable with choice of HL760 or CR600 receivers
• Mask mode eliminates interference from other crews on the jobsite
• Automatic Grade Match and PlaneLok

Applications

• Leveling concrete forms and footers 
• General construction vertical alignment and plumb such as anchor bolt and form alignment
• “Over the top” sewer and storm drain pipe installations
• Sports fields, tennis courts and driveways
