Four temperature-compensated 360-degree CAN-based tilt sensors measure angles from cab, boom, stick and bucket, the company says. The system includes two GPS+ antennae, GPS+ receiver, and GX-60 control box. GX-60 provides an in-cab display that shows operators where the machine is on-site and what the bucket position is.
