Trimble ST400 Sonic Tracer

The Trimble ST400 Sonic Tracer uses ultra-sonic signals to maintain a set distance or elevation from an object, a design surface, or the ground. When mounted to a motor grader or dozer blade, the ST400 Tracer can be used to reference a string line, curb and gutter, or previous pass as a grade control reference.
