Hello Garmin Comm - I am having an issue with my Fenix 3 and a paired HR Strap. I do inline skating and often skate with the hands / arms behind the back. Once I do this my HR strap is not picking up on the watch. On long 20m+ training sessions putting the arms behind for areo / energy conservation is the norm. What can I do to help this issue. Do I need to get a different HR ban?
