Garmin Secret Menu
There is a secret menu hidden away in the depths of the menu systems of many top-end Garmins, including my Garmin Fenix 6 Pro and Forerunner 935, so it’s almost certainly been around for months or years. It probably isn’t that secret either but, hey, it’s news to me. Thank you @Pavel for the heads up.
You can find it in the Settings>About menu. Just press the top left Light button about 8 times and you will enter the murky world of the debug menu. Feel free to play around with these settings and do your very best to break your expensive sports watch. Hint: Don’t.
