Spectra Precision Laserplane GL422N dual slope laser level was built from the ground up with long range and precise grade applications in mind. From agricultural land leveling to commercial sites, there isn't another laser available that can deliver slope this accurately or easily. Accurate, stable and reliable, GL422N is ideal for longer range measurements across your entire site. Spectra Precision GL422N is construction tough, precision laser instruments designed for ease of setup and use by anyone. With high-speed self-leveling, there's no leveling screws! No bubble vials! Just turn it on, and in seconds you're working. Convenient push-button control and power management options contribute to the GL422N simplicity. Spectra Precision GL422N features a 2-way, full function remote control with a built-in back-lit grade display. You can do everything with the remote control that you can do at the laser keypad, including grade reverse on both axes, up to 330 feet away from the laser even from the cab of the machine! The ability to make grade changes from anywhere on the job greatly reduces setup time and speeds operation, especially when multiple job grade breaks are needed. GL422N laser system now includes the advanced HL760 Digital Readout (DRO) receiver that provides automatic Grade Match measures and displays the existing grade over unknown ground and eliminates time consuming and error prone calculations, and PlaneLok automatically locks on to an existing elevation or vertical alignment point which eliminates all drift or possibility of error due to improper calibration or weather and the unique "Fingerprint" function - receiver only accepts the beam from the laser it is paired with. Additionally, the GL422N grade laser self-plumb in the vertical position, to allow an even wider range of applications such as anchor bolt installation, plus form, tilt up and curtain wall plumbing. GL422N also incorporate automatic temperature and grade compensation for high accuracy in any weather or geographical location. GL422N laser beam can be turned off electronically on up to 3 sides of your choice. This capability eliminates interference with other crews on the job site by keeping the beam from straying into other work areas. The GL422N offers two additional advanced features: pointing mode for “Over the Top” pipe laying applications and grade match where the laser can be used to measure the existing grade value between two known elevation points. Spectra Precision GL422N is built JOBSITE TOUGH! Slope control has never been this easy. Spectra's waterproof housing ensures maximum productivity anytime, anywhere.
