Earthworks X300 excavator guidance system integrates Crescent Vector GPS compass technology to measure and display 3-D excavating positioning. It provides real-time visual feedback on the position of the bucket teeth relative to design grade surface. It also functions in a full 2-D mode when jobs don’t require a 3-D design file; a touchscreen interface guides operators through 2-D jobs. Hemisphere GPS. 480-348-9919.
