While snow skiing and recording the activity, my 67i constantly beeps (every 3-4 seconds) when riding the chair lift and actually skiing. Then while I get to the bottom of the hill and I have look at the screen, the screen is off and the beeping has stopped.
My research has told me this may indicate loss of satellite connection however I have it set to Multi-GNSS & Multi-Band and I'm at the top of a mountain (even on clear days) so I don't know how it would struggle to get a satellite connection.
