  • 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° perpendicular
  • (+/-40° alignment range on Y- and X-axis)
  • Automatic Grade Match (Y- or X-axis separate) measures and displays the existing grade over unknown ground and eliminates time consuming and error prone calculations, time spent searching for grade plans, and over excavating (X- only GL622)
  • Automatic PlaneLok (Y- or X-axis) 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 (X- only GL622)
  • Very rugged, survives a 1 m (3 ft) drop on concrete—reduces service and repair costs
  • Mask mode eliminates interference with other crews on the jobsite
  • Different rotation speeds (continuously adjustable) plus Scanning Mode offer additional value and make sure also requirements of Interior jobsite will be fulfilled (only GL622)
