When it comes to picking a heart rate monitor to use with Argus, you have a couple of great options that were extensively tested:
Instant Heart Rate iPhone App
Instant Heart Rate is one of the easiest tools to get as the app uses your phone's camera to accurately measure heart rate. All you need to do is place your finger over the phone's camera lens and the measurement will take 15 seconds. Be sure to stand still while measuring.
