The PoolMate 2 takes distance counting to the next level by allowing you to track your distance in open water, perfect for triathlon training or just exercising out in the elements. It allows you to keep track of laps, strokes, distance, speed, efficiency, duration, sets, rest time and calories in the pool and in open water (minus the lap count in open water) and stores 50 sessions for recall, records and is water resistant to 50m and includes a 24 hour clock, alarm and a chrono mode for timing other sports.
