Spectra Precision Laser GL412 single-grade and GL422 double-grade lasers can perform three types of jobs, says Trimble: level, grade and vertical alignment with plumb with no manual leveling. A continuous, self-leveled 360-degree laser reference is sent over the work area. The beam can be turned off electronically on up to three optional sides to prevent interference with other work areas. Lasers can withstand a drop of up to three feet onto concrete, the company says. Two-way, full-function remote control has built-in backlit grade display.
