Pool Mate Live
€115, CABLE €35, TRITRADE.IE
Ever lost count of the number of laps you are doing in the pool? Set inside this convenient wristwatch is a built-in accelerometer that senses your movement and ticks over at the end of each lap. The hard-wearing glass face is easy to read with goggles on, tracks distances reasonably well and, when you plug it in, can give you details on efficiency and more.
A good gadget to keep you focused in the pool.
It's bulky on your wrist. The download clip is an additional cost.
