The IRTrackStar RS Ultralight is the lightest IRTrackStar yet, weighing just 3.1oz. The IRTrackStar increases performance over the standard Trackir5 pro clip by increasing precision, removing all blind/dead spots, and provides a wireless head tracking solution with over 9hrs of runtime. Trackir5 or Opentrack with a suitable webcam is required.
