The Wahoo Blue SC is the world's first Bluetooth Smart (4.0) cycling speed/cadence sensor made for the new Low Energy band of Bluetooth. Easy to pair to the Satmap Active 12, this sensor allows you to monitor pedal revolutions (cadence) and wheel speed. All the data is stored in the universal TCX format, for later upload to your favourite activity website.
Cadence data is very useful for improving cycling efficiency, stamina and endurance, and allows you to make better use of the bike gearing over a variety of terrains. Speed derived from the rotation of the wheels is a good backup and alternative to speed derived from your GPS location. Unlike GPS speed, wheel speed is not subject to poor signal issues from overhead tree cover or tall nearby buildings. Wheel speed and GPS speed are available as separate data items on the Active 12.
Wahoo's Speed & Cadence sensor is especially easy to fit and very secure. No zip ties are required; instead, a super-secure thick rubber strap is used to hold the sensor securely in place and is easy to adjust. Likewise, the crank and wheel magnets are no-fuss.
Also recommended: Wahoo Heart Rate Monitor. Used in conjunction, and with the Active 12, both these sensors will give you a complete picture of your cycling activity and workout, all in a standard format to upload to your favourite site, including route taken, elevation profile, average total speed, average moving speed, cadence, average cadence and heart rate data.

Not a problem - this great sensor can be used with a number of smartphones and tablets, including: iPhone 5, iPhone 4S, iPod Touch (5th generation), iPad (3rd and 4th generations). This sensor and downloadable Wahoo App combination transforms your iPhone into a powerful cycling computer. The Wahoo Blue SC connects wirelessly to your iOS device (no Wahoo Key or Bike Case required) and tracks your cycling speed, cadence, and distance through the free Wahoo Fitness App.
