Bluetooth turn time tracker
Swimtraxx has developed a swim tracking device that helps you track the rotational speed of every turn in real time. Swimtraxx One works with Bluetooth connection. After measuring your turn time during a swim workout the data gets sent to the Swimtraxx app where you can keep track of all your swimming information.
Because Swimtraxx One measures turn time next to many other swim specific parameters, it’s the smartest swim specific system ever.
