Smoothtrac
Topcon's Smoothtrac Sonic Averaging System is a proven advantage over a traditional mechanical ski.
Advantages of Smoothtrac vs a Mechanical Ski
Superior smoothness and ride-ability
Smoothtrac uses four non-contacting Sonic Trackers which are positioned along a 25 Ft. aluminum beam. Choose dual sided Smoothtracs, or run on one side with a Sonic Tracer or Slope Sensor to control the other side.

Saves set up and tear down time.
Smoothtrac consists of an aluminum beam, four Sonic Trackers and cords and weighs a fraction of a mechanical ski. Save time whenever you have to get started, turn around , back up or remove the system.

Easier to transition from the SAS to a Single Sonic Tracker
Just unplug the SAS cord and plug directly into a Sonic Tracker for matching a joint or tracking off a curb, stringline etc. The Smoothrac can quickly be folded up and left alongside the asphalt paver.
