Garmin in their wisdom have disabled the 'incident detection' feature when the activity is 'MTB'. Apparently this is that there were too many false alerts.
In all my mountain biking I have only ever set it off once, when I crashed, and as I was ok I cancelled the alert. It was reassuring to know though that if I had been knocked unconscious that an alert would have been sent (although you shouldn't rely on this).
If others are setting off the alert frequently due to lots of jump activities, either they can put up with cancelling the alerts (they don't inconvenience the emergency services), or disable the function on their watches. Instead Garmin have just disabled it for all mountain bikers.
I contacted Garmin. They said sorry, but tough, but that they may, or may not reconsider if they were contacted by enough people. Hence it would be great if people could contact Andy at [email protected]
Thanks
