A laser-based system, such as the Trimble Spectra Precision Laser LR50 or LR60, is an option. These systems improve precision for grading, pad construction, and ditch work by using a laser receiver on the blade. As an alternative, think about the Leica iCON iGD2 system, which offers grade information in real time via a receiver on the blade and an intuitive control panel. The Topcon 3D-MC2 system combines laser and GNSS technology for more sophisticated functionality, providing semi-automatic control for improved precision in a variety of grading applications.
