Best underwater time tracking device

Swimtraxx has developed a swim tracking device that measures tons of data that is translated into real-time valuable insights. One of the measured parameters is underwater time. Swimtraxx One tracks your time under water. Because every breakout counts Swimtraxx One helps you get a clear view of your hypoxic effort for every lap.

Swimtraxx One gets clicked onto the side of your swimming goggles and therefore tracks all the data while being in the water. 

With Swimtraxx One you can easily keep track of your swimming workout routine. You can look up all registered data on the Swimtraxx App at any time. 

Because Swimtraxx One measures underwater time next to many other swim specific parameters, it’s the best swim specific tracking system ever.
