Spectra Precision® GL622 Grade Laser.
The GL6x2 Range of Grade Lasers provide either single or dual grade capability in addition to being fully self-levelled in vertical for building axis alignment or setting 90 degree. Simple, robust and easy to use with a menu driven interface that is replicated on the radio remote control makes the GL612 (single grade) and GL622 (dual grade) the first choice for any contractor requiring grade capability.

The GL612 Single Grade Laser and GL622 Dual Grade Laser are rugged, automatic self-levelling lasers with grade capability from -25% to + 25% and can be used for a wide variety of grade, excavating and alignment applications by general and speciality contractors.

 Both lasers come with a radio remote control that provides fully functional capabilities up to 100m (330 feet) from the laser transmitter – even from the cab of a machine. The graphical, menu driven interface makes the lasers simple and easy to use and can be set to 16 different languages. The ability to operate the laser whilst working away from the laser transmitter can significantly reduce set-up times and increase productivity.

 Each laser package includes the advanced HL760 Digital Readout Receiver that can be used at an operating diameter of up to 800m (2,600 feet). The Digital Readout allows the user to get to the on grade position faster as the distance is displayed to the on grade position in mm, or inches, fractional inches. Wireless communication between the receiver and the laser allows advanced functionality such as Automatic Grade Matching to be achieved. Automatic Grade Matching basically means that the laser moves to the on-grade position on the receiver and the grade is then calculated – this is generally used when a constant fall is desired but the grade may not be known (renewing existing driveways or matching existing surfaces). The HL760 can be paired with another HL760 turning the second receiver into a remote display that could allow a machine operator to see what the rodman is seeing when dipping for levels. 

Both GL612 and GL622 are self-levelling in vertical, allowing more productivity by being able to carry out more tasks such as building axis alignment or setting 90 degrees or aligning anchor bolts. Designed to be used on the toughest jobsites the GL612 and GL622 can withstand a 1m (3 feet).


  • Automatic electronic self-leveling provides fast, easy horizontal level, grade, and vertical plumb setup
  • Large compensated grade range from -25% to +25%
  • Quick setups with the radio remote control for horizontal, vertical and grade applications
  • Electronic Leveling
  • Vibration Filter dampens vibrations typically experienced on tall tripods, in high winds, or on high vibration jobsites
  • No rework due to automatic temperature and grade- and cross axis compensation
  • Automatic Axis Alignment doing precise automatic axes alignments to a desired alignment points without positioning the receivers 90
