Pool-mate lap and stroke counter

From their website: "The Pool-Mate is the only fully automatic lap and stroke counter for swimmers. It will work with all major strokes, all abilities of swimmer and all sizes of pool.

Containing accurate motion sensors and our unique software algorithms, the Pool-Mate automatically recognises each swim stroke and change of lap so you don't have to count anymore. The Pool-Mate will display Lap count, Time, Average Strokes per lap, Speed, Distance, Calories and Efficiency, all completely automatically and store details in a large memory for recall at your leisure."


Looks pretty cool, assuming it works.
