PowerDigger 3D is a cable-free system that can be easily transferred between excavators, dozers and graders for 2D and 3D applications. It expands on the PowerSnap concept, which makes it easy to swap panels between laser, slope, and 3D machine control. PowerSnap also offers complete backwards compatibility and affordable upgrade paths from traditional laser/slope control to 3D. The system supports full GNSS (GPS & GLONASS) coverage as standard.
