TOPCON SMOOTHTRAC
ADVANCED SCREED CONTROL

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.
