The small, water-resistant tempo trainer attaches conveniently to the strap of swimming goggles and helps you find the desired pulling frequency. You can adjust the meter to your desired frequency level, so the meter helps maintain the desired speed and frequency. The meter also includes a clip that can be attached to sneakers, for example for running training.
The audible sound stands out well in the water. Tempo can be adjusted up to 1/100 beat/second. Can be used e.g. for cycling, running and swimming. Small size, easy adjustability, fits well in a swimming cap. Water resistant. Closes automatically if the meter is left on.
