Single Grade Laser with 25% Grade Range. Spectra Precision® GL622N Grade Laser - Easy-To-Use, Full Featured Automatic Grade Laser. The GL622N Single Grade Laser is a rugged, automatic self-leveling laser 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. The GL612N comes with a radio remote control that provides fully functional capabilities up to 150m (500 feet) from the laser transmitter - even from the cab of a machine. The graphical, menu-driven interface makes the laser simple and easy to use and can be set to 16 different languages.The ability to operate the laser while working away from the laser transmitter can significantly reduce set-up times and increase productivity. Laser packages may include the advanced HL760 Digital Readout Receiver that can be used at an operating diameter of up to 800m (2,600 feet). 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. Both 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.
