What is the Trimble ST400 Sonic Tracer?<\/h2>\n

The Trimble ST400 Sonic Tracer is an ultrasonic grade control sensor used on dozers and motor graders to maintain accurate elevation based on a physical reference such as stringlines, curbs, gutters or previous passes. It helps operators achieve consistent grading results without relying on GNSS<\/a> or laser systems.<\/p>\n
