Wahoo TRACKR Heart Rate Sensor

The Wahoo TRACKR heart rate sensor is the first heart rate monitor from leading manufacturers in the market to use a high-capacity integrated lithium-ion battery instead of a button cell. This protects the environment and makes the sensor less likely to suffer damage. Thanks to the Multiple Peripheral Bluetooth function, the Trackr Heart Rate can maintain up to 3 parallel Bluetooth connections at the same time. Easily visible LEDs on the top indicate the status of the heart rate sensor.Features:Material: PlasticWater resistance: 1 m water column for 30 minutes (IPX7)Size: 66.7 - 87.5 cm (adjustable); maximum chest circumference 127 cmData transmission signal: Bluetooth, ANT+Battery: integrated and rechargeable lithium-ion battery; approx.
