It is an outstanding tool for training communication between the coach and students on the open water field. By the transmitter, the coach can give students continuous technical corrections from the Coast. This allows the swimmer to get real time hints about stroke rate, lap times, feedback during turns and rhythm or breathing cycles changes, and so on.
