Spectra Precision GL710 & GL720 Grade Lasers
- Precision High Accuracy, Extra Long Range Grade Lasers
- The GL700 series grade lasers are the longest distance, most accurate, and most durable of Spectra Precision Lasers.
- The rugged die cast housing, advanced leveling technologies, and temperature compensation make the GL710 and GL720 lasers the best choice for long distance applications and machine laser display.
- Manufactured in the USA
Features:
- 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 from a short distance
- Better than 5 arc second servo deadband accuracy for demanding high accuracy requirements
GL710 Single Grade Laser:
- Up to a 900 meter (3,000 foot) diameter.
- With -0.5 to 25% grade range,
- the GL710 is a great choice for general construction, site preparation, trenching and pipelaying 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 900 meters (3,000 feet) diameter.
- The GL720 is ideal for general construction and machine control grade applications
The Spectra GL722 Grade Laser
The 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.
Features & Benefits
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 GL700 Series easy to use and learn
Long Life Battery - flexible power options, battery life indicator and wireless operated sleep mode that saves battery during breaks
Fully 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 for example from +1% to -1%
Automatic off-grade sensor - prevents incorrect grading and wasted man and machine hours
Long range remote - 225m (750ft) for general operation and 150m (500ft) 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 – The GL722IR provides all the benefits of the standard model but with Infrared beam
