Trimble’s innovative technology ensures higher accuracy than ever before over a variety of machine control and general construction applications. Plus, unique features help reduce beam drift errors and speed up setup and grade changing to optimise worker and machine productivity. The Spectra Precision Laser GL700 Series from Trimble has four robust models, so you can select the right laser transmitter for the right application. Each model in the GL700 Series is designed to be simple to set up and use.

The Spectra Precision GL720 is easy to use and provides long range, high accuracy dual grade capability. With a grade range of ±10% in the X-axis and -0.5 to +25% in the Y-axis, combined with a 900m (3,000 feet) operating range no job is too small for this laser. The GL720 is ideal for general construction and machine control grade applications.
