I don’t really track fitness, not sure what data my Garmin Instinct gives me that tells me, other than HR and sleep info. Im sure if I learned all the features, it would tell me stuff, not interested currently. I do use my Instinct (2 Solar) to send HR to my Edge 1040 when riding, as well as it tracks my swim workouts in a pool, or can track open water swims, as well as tracks my kayak trips. Every completed activity goes to RWGPS via Connect, which is a requirement as that’s my activity tracker. Since it allows Live Track via the Garmin Connect Mobile App, my wife knows where I am when solo kayaking (when there’s cell service), which is useful. I have seen 42 days in a charge on this watch when I am riding and kayaking hub summer, usually battery is 24 days or so between charges.
