Trimble's GCS600 for excavators is an entry-level product designed to provide a flexible grade-control solution for elevation and slope applications. The system is easy to install, set up and use on excavators with standard buckets or tilt buckets. By adding the AS300 Angle Sensor, the system will work with articulated booms or tilt buckets. It displays required depth and working slope, and lets the operator work across a greater area and slope distance without returning to the laser transmitter each time the machine moves. The system is part of Trimble's Grade Control System family and can be upgraded.
