Wahoo Blue HR Bluetooth Heart Rate Belt
The Wahoo Blue HR heart rate monitor has been designed to be as quick and easy as possible to put on before your cardio or workout.
Wearing the heart rate monitor belt
Many heart rate monitor belts will rely on you having to connect the clips in front of you before rotating it round your body so the clips are at the back.

With the Wahoo Blue the connector for both ends of the strap is the heart rate monitor unit itself.
You can simply pass the belt around your body and clip each end into the back of the main unit. This removes the need to then raise it up around your body and rotate the belt which can lead to the belt rolling over and giving incorrect readings.
Bluetooth connectivity
The Wahoo Blue uses the new Bluetooth 4 transmission which is identical to the Bluetooth 3 but uses less power. This is important for preserving the battery life of your phone if you are carrying it with you to display your progress during your run.
While some other smart phones are starting to offer Bluetooth 4, the Wahoo Blue has been designed primarily for use with the iPhone 4S and iPhone 5 smartphones.

Being able to secure the belt so easily without having to twist it around your body after, and the clear display of how long your heart rate was in different ranges are two very useful features that make this Heart Rate belt unique.
