Collect heart rate data during your workout and easily read the data on your iPhone when paired with the Fisica Sensor or Case. 

The Wahoo Fitness Heart Rate Strap strives to reach the ultimate balance of accuracy, comfort and economy. Unlike earlier model heart rate straps made largely of plastic, the Wahoo Fitness strap is made of a comfortable elastic fabric with integrated sensors to receive electrical heart impulses. The soft fabric is ideal for maintaining alignment and for providing a comfortable feel while minimizing any chance of chaffing.

The electronics inside the Wahoo Fitness Heart Rate Strap analyze heart rate activity and transforms electrical activity produced by the heart into digital information. This data is transmitted to a receiver using the ANT+ protocol, the most widespread and robust procedure for wireless communication among fitness sensors. Unlike heart rate sensors that simply transmit raw analog heart rate activity that is processed by the receiving unit, the Wahoo Fitness Heart Rate strap is unaffected by periods of lost communication with the receiving unit so that if the Strap and the receiving unit become separated and rejoined, the receiver will provide accurate heart rate information, even for the period when it couldn’t find the sensor.

Although the Wahoo Heart Rate Strap is specially designed to work with the fisica wireless sensor interface, because it transmits using the standardized ANT+ protocol it works with any of the myriad heart rate receivers and watches that communicate using ANT+. 

Fisica wirelessly connects your iPhone to your favorite ANT+ fitness measuring devices. With fisica, your phone, your favorite playlists, the best fitness Apps and real-time activity information are all in the palm of your hand - or on your arm, or mounted on your bike, or in your pocket.

What is it?

• Your Wahoo Fitness Heart Rate Strap is a device worn in proximity to the heart that gathers electrical activity data to derive your heart beats per minute.

How do I use it?

• Thoroughly wet both electrodes on the Strap with water or electrode gel. It is important that the electrodes are sufficiently moist so that a good skin-toelectrode connection is made.
• Snap one end of the Strap to one side of the Pod. Either end of the Strap can connect to either end of the Pod, but the Pod should have the Wahoo Fitness logo facing up when in use.
• Wrap the Strap around your back and snap the free end to the free side of the Pod so that the Pod is located on your breastplate, just below your breasts. Adjust the Strap to create a snug, yet comfortable fit.
• Once in place, move within 5’ - 10’ of any device that receives ANT+ wireless data.

It won't connect! What do I do?

• If you do not get a reading, or the readings are erroneous, ensure that the electrodes are wet, have good contact with your skin and the that your Heart Rate Sensor is sufficiently snug. Your Heart Rate Sensor ‘sleeps’ with inactivity and ‘awakens’ with good electical contact. A brief physical warm up may be required.

How do I pair it with my device?

• Each Wahoo Fitness Sensor has a unique identification code and can be uniquely paried with a display device or reader so that it will always be recognized when it is activated and within range. Since each reader is unique, you should reference the instructions of your reader for pairing techniques.

How do I change the battery?

• The battery in your Wahoo Fitness Stride Sensor is located behind a cover on the back of your Heart Rate Sensor Pod and can be replaced by placing a coin in the slot and turning the cover 1/4 turn counterclockwise. Replace with a 3 volt CR2032 battery (contact a local waste handling group for proper disposal of old battery). Wait 45 seconds before installing the new battery to ensure the electronics fully reset.
