Tempo Trainer Pro

The Tempo Trainer Pro from Finis is a waterproof device that easily hides under a swim cap and sends an audible tempo beep. The athlete uses the device's audible signal to maintain their opimal or race pace to enhance their performance. The Tempo Trainer Pro now comes with a replaceable CR1620 3V battery, so you can use the device repeatedly. The Tempo Trainer Pro includes a clip for attaching it to your glasses strap or for use in other sporting activities. A great advantage is that if you drop the device into the water, it will float on the surface. The audio signal of this device can be heard both underwater and out of the water. The tempo can be set up to 1/100th of a second. This device is not only suitable for swimming, but also for cycling, running and other sports.
