* Did I mention the poor [[GPS Accuracy]] enough yet? Well, that is probably the biggest flaw in this watch.
* The Fenix 3 includes an internal accelerometer to give you an idea of pace and distance while running on a treadmill without a footpod, but I found the accuracy was rather poor. I have yet to come across a watch that can reasonably estimate your pace from the movement of your wrist, nor does it seem likely that this functionality is practical.
* You need to have the new HRM for the some of the features. The Fenix 3 will display Heart Rate and calculate [[Firstbeat| Training Effect]] with the older Garmin HRM, but not Ground Contact Time or Vertical Oscillation. There is a version of the Fenix 3 with an [[Optical Heart Rate Monitoring| optical HRM]], but it's the same technology as found in the [[Garmin 235]] which I found to be rather useless.
=What's Missing=
While I don't consider these missing features as 'cons', it's worth understanding the features that are missing compared with other watches. You'll notice that the Fenix 3 has a rather short list of missing features.
