I love my new F5 S Plus. It is a huge upgrade from my Forerunner 235. After spending the weekend obsessively learning and playing with all the new options, I have submitted one feature/option modification request to the Garmin suggestion box: Move the "Broadcast Heart Rate During Activity" option from the current global setting to the individual activity. For example: I want to broadcast my heart rate to my indoor cycling trainer game (Zwift); but I don't need to waste battery by broadcasting heart rate during a run or outdoor cycling. The current setting is under Heart Rate Options and once set, broadcasts heart rate for all activities which consumes additional battery even for activities when you may not want to broadcast. I am aware that you can manually turn on the heart rate broadcast; but once you start to broadcast, you can't then return to the menu to start an activity.
