Open water tracking

COROS watches support freestyle stroke types in Open Water mode for accurate GPS tracking. Breaststroke, Backstroke and Butterfly styles don’t have a guaranteed GPS tracking.

In order to ensure the GPS tracking accuracy, please wait until you receive a confirmation from the watch about GPS acquisition before jumping into the water. Make sure to provide substantial amount of time for the watch to stay out of water during your strokes as GPS signals can’t travel underwater.
