It also features IP67 rating moisture and dust sealing to handle the tough construction environment. With its rugged design, the GL622N laser level can survive a drop of up to three feet on concrete. Mask mode eliminates interference with other crews using a laser onsite and electronic leveling vibration filter reduces vibrations typically experienced on tall tripods, in high winds, or on high vibration job sites. The Spectra GL622N incorporates automatic temperature and grade compensation for high accuracy in any weather or geographical location. The included Spectra HL760 laser receiver provides a digital readout of elevation and features an anti-strobe detector that prevents false readings from site strobe lights. The self-plumb in the vertical position enables an even wider range of applications such as anchor bolt installation, form, tilt-up, and curtain wall plumbing. It also has an automatic dual grade range of ☒5% in both axes, providing a fast and easy horizontal level and vertical plumb setup. ![]() Ideal for agricultural and construction applications, the Spectra GL622N grade laser delivers a self-leveling accuracy of ☑/16 inch. This allows construction professionals to easily perform axis alignments for grade work applications such as sports fields, parking lots, tennis courts, driveways, or any irregular field with non-perpendicular grade profiles. Automatic axes alignments can be accomplished by positioning the laser receiver at the direction hub in a range of ±40° at the desired laser axis. ![]() Capable of tilting on both axes for precise measurement of slopes, the GL622N laser can be used in a wide variety of outdoor grading and excavating. With an intuitive keypad and graphic LCD, this rotary laser features automatic axis alignment and offers PlaneLok and grade matching capabilities for highly-accurate results. The Spectra Precision GL622N is a self-leveling, dual-grade construction laser with long-range operation up to 2,600 feet.
