Product Description

Spectra Precision GL422 Grade Lasers w/ HL700, Remote Control , Nimh batteries


Rugged New Grade Laser with Two-Way Radio Remote Offers Superior Grade, Level and Vertical Capabilities

The Spectra Precision Laser GL412 (single grade) and GL422 (dual grade) transmitters are costeffective, automatic self-leveling lasers that do three jobs—level, grade and vertical alignment with plumb.

Both the GL412 and GL422 feature a 2-way, fullfunction remote control with a built-in back-lit grade display. You can do everything with the remote control that you can do at the laser keypad, including grade reverse on both axes, up to 100 m
(330 ft) away from the laser—even from the cab of the machine! The ability to make grade changes from anywhere on the job greatly reduces setup time and speeds operation, especially when multiple job grade breaks are needed.

Additionally, the GL412 and GL422 Grade Lasers self-plumb in the vertical position, to allow an even wider range of applications such as anchor bolt installation, plus form, tilt up and curtain wall plumbing. Both units also incorporate automatic temperature and grade compensation for high accuracy in any weather or geographical location.

On both models, the laser beam can be turned off electronically on up to 3 sides of your choice. This capability eliminates interference with other crews on the job site by keeping the beam from straying into other work areas.

The GL422 offers two additional advanced features: pointing mode for “Over the Top” pipe laying applications and grade match where the laser can be used to measure the existing grade value between two known elevation points. Use this versatile laser with a Spectra Precision Laser HL700 Laserometer at an operating diameter up to 800 m (2,600 ft), or use it with the CR600
machine-mounted laser receiver for fast and easy machine control display.

Spectra Precision Laser HL700 Laserometer
The Spectra Precision Laser HL700 Laserometer uses new technology to measure and display beam location and is ideal for use with the GL family of transmitters. The HL700 features a digital readout of elevation that shows exactly how far you are from on-grade allowing quick elevation checks without moving the rod clamp. The large 127 mm (5 inch) reception height speeds up beam pickup in grade match and alignment applications. An anti-strobe sensor stops construction lights from setting off the receiver, and makes it easier to identify true laser beam signals. The protective over molded housing withstands a drop of 3 m (10 ft) onto concrete. The highly visible LED display and dual sided LCD’s allow you to work anywhere.

Spectra Precision Laser CR600 Receiver
Another receiver option is the Spectra Precision Laser CR600 Receiver. In addition to use as a handheld and rod-mounted receiver, the CR600 can be used as a machine control mounted receiver with 270-degree reception and a highly visible
display for use on a backhoe, small excavator or skid steer. Rugged, accurate and easy to use, the CR600 provides high, low or on-grade information for all your grading and excavation applications.


  • Fast, easy horizontal level, grade and vertical plumb setup with no manual leveling
  • Easy setups with the 2-way, full-function radio remote control and single and dual grade application capability offer quick payback
  • Automatic temperature and grade compensation eliminates rework
  • Very long operating range of 800 m (2,600 ft) for GL422 increases machine control capability and reduces setups over the jobsite.


  • Leveling concrete forms and footers
  • General construction vertical alignment and plumb such as anchor bolt and form alignment
  • Grading and excavating
  • Concrete sections with runoff for sports fields, tennis courts and driveways
  • Steep slope road embankments and ditch banks
  • Parking garages, ramps and drainage
