Sonic Tracker II
The Sonic Tracker II measures and controls the elevations of the
moldboard. A transducer, located in the bottom of the Sonic Tracker
II™, generates sound pulses like a speaker and listens for returned
echoes like a microphone. The Tracker measures the distance, and
controls grade from a physical grade reference, such as a curb,
stringline, or existing road surface.
The Sonic Tracker II attaches to the system through one quick
connect cable and attaches to the machine with a single bolt. At the
end of the day, Sonic Tracker II should be removed for proper storage
in the carrying case.
