Sonic Averaging System (SAS)


Topcon’s Sonic Averaging System has been the paving industry’s first choice as a non-contacting replacement to the conventional mechanical ski. The Sonic Averaging System is comprised of a 24 ft. aluminum beam holds four Sonic Trackers which continuously measure the elevation over the surface, automatically averaging and adjusting tow point cylinder. The SAS is convenient, maneuverable and produces a great finished surface.
