Features & Benefits

  • Temperature compensation provides accurate stable results regardless of temperature changes
  • Long battery life and flexible power options keep the unit working throughout the day
  • Large displays make the numbers easy to read, even when set-up on a tall tripod
  • Better than 5 arc second servo deadband accuracy for demanding high accuracy requirements

GL710 Single Grade Laser

  • Up to a to 3,000 foot (900 meter) diameter. With -0.5 to 25% grade range, the GL710 is a great choice for general construction, site preparation, trenching and pipe-laying applications

GL720 Dual Grade Laser

  • The GL720 features +/- 10% in the X axis grade range and -0.5 to +25% Y-axis grade range with high accuracy up to 3,000 foot (900 meter) diameter. The GL720 is ideal for general construction and machine control grade applications

GL722 Dual Grade Laser

  • With a Long-range Radio Remote and the same range and base capabilities as the GL720, the GL722 includes all the benefits of the full Radio Remote functions… plus Automatic Axis Alignment, Grade Match and PlaneLok capability. Ideal for general construction, site preparation and road construction
