• Laser Only
• Provides the ability to control level, alignment, dual grade and set 90 degrees.
• One person elevation and grade control with 800 m (2,600 ft) diameter range increases productivity
• Provides fast, easy set-up for horizontal level, grade, or vertical alignment
• Large, fully compensated grade range from -25% to 25% - keeping the laser levelled no matter what grade you need reducing errors and improving productivity.

Spectra Precision GL622N Grade Lasers - Easy-To-Use, Full-Featured Automatic Grade Lasers

The GL622N Dual Grade Lasers are rugged, automatic self-leveling lasers with grade capability from -25% to + 25% and can be used for a wide variety of grade, excavating and alignment applications by general and specialty contractors.

Radio remote control provides fully functional capabilities up to 150m (500 feet) from the laser transmitter can be purchased separately. 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.

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. Receiver must be purchased separately.

The GL622N is self-leveling 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. The GL600 series can withstand a 1m (3 feet) drop.
