It’s the Pool-Mate automatic lap and stroke counter watch from Swimovate. The watch has accurate motion sensors that can recognize each swim stroke and change of lap so you won’t need to count anymore. It displays Lap count, Time, Average Strokes per lap, Speed, Distance, Calories and Efficiency and stores the details in a large memory for later recall. Pair this with the Finis SwiMP3 and you have an amphibious gadgeteer 😉
