Product Overview

The Spectra Precision GL722 dual grade laser is one of the most advanced grade lasers on the market. The long range operation, advanced radio remote, grade matching, Planelok and Automatic Axis Alignment features mean that you can do quick but highly accurate set-ups for any grade application.


  • Active Temperature Compensation - accurate, stable results regardless of temperature change
  • Long Range Wireless Link - unaffected by direction or sunlight provides quick, accurate set-up even when the laser is on a 3m tripod and provides full functional control of the laser
  • Protective Lens Hood - ensures laser performance in inclement weather means the laser will work when you are working regardless of weather
  • Intuitive, simple controls - makes using the GL722 easy to use and learn
  • Long Life Battery - flexible power options, battery life indicator and wireless operated sleep mode that saves battery during breaks
  • Full sealed, rugged aluminum housing - with weather-resistant control panel, allow you to work in all weather and work conditions
  • Grade Bump - allows you to simply raise or lower the grade remotely
  • Grade Reverse - mirrors the grade setting with the push of a button, flipping the set grade
  • Automatic off-grade sensor - precents incorrect grading and wasted man and machine hours
  • Long range remote - 225m (750 ft) for general operation and 150m (500 ft) for automatic alignment
  • Automatic Axis Alignment - allows you to align automatically to your grade hub eliminating costly error by not being aligned correctly when using grade
  • Machine Control Compatible - works with all laser-based machine control systems
  • Infrared Model - for rail work where red beams are not allowed on live track - GL722-IR provides all the benefits of the standard model but with infrared beam
