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. 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. 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. 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. </p>
<p data-mce-fragment="1">Ideal for agricultural and construction applications, the Spectra GL622N grade laser delivers a self-leveling accuracy of ±1/16 inch. It also has an automatic dual grade range of ±25% in both axes, providing a fast and easy horizontal level and vertical plumb setup. 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.</p>
