Combining many lasers into one unit, the Spectra Precision UL633 Universal Laser provides grade in three axes and allows contractors to control a multitude of applications with one tool. The laser provides a 25% grade range in the X and Y axes for single and dual slope work, and with the SpotFinder, the UL633 can automatically align the beam for pipe laying applications.
