Spectra Precision GL412 Series; GL412, Single Slope Laser w/HL700 Detector, Remote, NiMH System, Manual & Case.

Versatile Automatic Grade Lasers for Level, Grade and Vertical Alignment

The Spectra Precision® Laser GL412 and GL422 Grade Lasers are cost-effective, automatic self-leveling lasers that do three jobs—level, grade and vertical alignment with plumb. Both lasers feature a 2-way, full-function remote control so you can make grade changes from anywhere on the jobsite for reduced setup time and faster operation.

The GL412 (single grade) and GL422 (dual grade) lasers send a continuous, self-leveled 360-degree laser reference over your entire work area, and have a wide grade range so they can be used in a variety of slope applications.

Features

Fast, easy horizontal level, grade and vertical plumb setup with no manual leveling
Easy setups with the 2-way, full-function radio remote control and single and dual grade application capability offer quick payback
Automatic temperature and grade compensation eliminates rework
Very long operating range of 800 m (2,600 ft) for GL422 increases machine control capability and reduces setups over the jobsite.
