The Spectra Precision GL422N Dual Grade Laser was designed for a wide range of general construction, site preparation, and excavations. This rugged, automatic slope laser provides contractors with accurate leveling, grade, and vertical alignment. With a working range of up to 2,600 ft. and it has a grade capability of 10% to plus 15% on both axes. The GL422N is also self-leveling horizontally and vertically within 5% and has an accuracy of 1/16 in. per 100 ft. For anchor bolt and form alignment, it self-plumbs in the vertical position and can be mounted on a 5/8-11 tripod thread vertically or horizontally. The Spectra RC402N full-function remote control comes standard with the GL422N grade laser and offers an easy to use menu-driven interface. With a working of up to 330 ft. this radio remote gives the ability to make long-range grade changes and automatic alignments. The Spectra GL422N has an out of level alert that shuts off the grade laser if it is knocked out of place to prevent inaccurate readings. It also has a selection of sensitivity for accurate results even in high winds or on high vibration job sites. With an IP66 rating, this laser level is dustproof and can be used in heavy rain. It can also withstand drops of up to 3 ft. onto concrete and tripod tip-overs up to 5 ft. This slope laser uses NiMH batteries and works up to 35-hours of continuous use.

I have used the Bosch and Johnson Rotary Laser Levels. but I never felt so at ease then with this Spectra Laser. It’s very easy to operate, basically plus and play right outside of the box. I loved the remote option which I don’t think anyone else has.Love this HL760
