What is it?
  • Your Wahoo Fitness Blue HR 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 Bluetooth Smart wireless data, such as the iPhone 4S.

How do I pair my Blue HR using the Wahoo Fitness App?
  • Open the Wahoo Fitness App
  • Tap the wrench icon in the top right for settings
  • Choose Workout Settings
  • Select the Workout Type
  • Choose Add Sensor
  • Select HR
  • It should start searching for the HR. You might also see the BT logo flash.
  • Click Save in the top right
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 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.
  • Make sure the Bluetooth setting on your device is turned on and that you have latest version of your favorite compatible app. 
  • Pair the heart rate strap in the app, not in Bluetooth settings.  In the wahoo app, it is under quick settings and then either pair new sensor (if you don't have a paired hr strap yet) or heart rate. You can pair the strap there.

How do I change the battery?
  • The battery 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).

I've been looking for a HRM for years but I'm too much a tech lover to settle for a watch with a display that looks like it's from the 90s. I wanted something from 2012 that is updatable via firmware. When I came across this, I knew it was a winner. LOVE that the monitor itself isn't tied to a particular app or interface. I use the Wahoo app during my workout and then synch the data to Nike+ (it exports my heart rate, pace, calories, route...). The Wahoo app is even better that over Nike+ (and others I've tried). Super flexible in terms of voice feedback. You can set just about any variable at any interval (distance, time or gesture). Pretty fantastic. Highly recommend.

I use the Wahoo Blue Tooth HR strap for cycling, spinning and other gym workouts. It connects easily and every time. I highly recommend this product!

It has worked perfect, exactly what I needed. It is light, the strap is comfortable, and is a reasonable price. If you have an iPhone 4s it's the way to go. I have never cared for wearing a wrist HRM, or a watch for that matter. I use it for running but have found I use it often when doing the P90X workout program. I have been at least 15 feet away with no signal loss, further then that you can't read it anyway. If you do get out of range it picks up the signal in a second or 2. Very pleased with the purchase. I suspect the apps will continue to improve. I wouldn't mind a really large display of just the heart rate to toggle to.
