Spectra Precision®  GL622N Dual Grade Laser — Easy-To-Use, Full Featured Automatic Grade Laser, The GL622N Dual Grade Laser is rugged, automatic self-levelling laser 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. It comes with a radio remote control that provides fully functional capabilities up to 150m (490 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. The GL622N is 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 GL622N can withstand a 1m (3 feet)

  • GL622N dual grade laser with a compensated grade range of -25% to +25%. Vertical and horizontal setups are also compensated
  • Quick setups with the 2-way radio remote control
  • Electronic Leveling Vibration Filter dampens vibrations typically experienced on tall tripods, in high winds, or on high vibration jobsites
  • Very rugged with low service costs; takes a 3 ft (1 m) drop on concrete
  • Mask mode eliminates interference with other crews on the jobsite
  • Automatic Axis Alignment (GL622N only) is easy to setup for increased accuracy
  • Radio communication between the laser and HL760 Laserometer allow advanced features and remote display capabilities
  • Long operating radio range - 490 ft (150 m)
  • Grade Match displays the existing grade over unknown ground and eliminates time consuming and error prone calculations, time spent searching for grade plans, and over excavating
  • 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
  • 5 Year “No Cost” Warranty
