Trimble announced the new Spectra Precision GL412 and GL422 grade lasers. The GL412 single-grade laser and GL422 dual-grade laser offer fast, easy horizontal level, grade and vertical plumb setup with no manual leveling. The GL412 and GL422 lasers send a continuous, self-leveled 360 degree laser reference over an entire work area, and feature a wide grade range of -10 to +15 percent, which allows them to be used for a range of slope applications. These lasers can withstand a drop of up to 1 meter (3 feet) directly onto concrete, and feature a two-way, full-function remote control with built-in backlit grade display. Both models also incorporate automatic temperature and grade compensation for high accuracy in any weather or geographical location. Additionally, the GL412 and GL422 lasers can be used with a Spectra Precision HR550 laser receiver at an operating diameter up to 800 meters (2,600 feet), or with the Spectra Precision CR600 laser receiver mounted on a machine for easy machine control display.
