Yeah, I did that every day of the PCT with my Fenix 3HR in 2017. Watches have come a long way.

I had my Fenix 3 HR for almost 10 years before switching to the F8 Solar. It was still working, not a single scratch on the sapphire glass (used it for rock climbing and in harsh environments). Only replaced it as the battery runtime started to decrease (had to charge at least once a week in the end) and mainly because I wanted the bee features 😁

Is the Instinct a touch screen? I had a Fenixn3 HR which I used for about 5 years. Upgraded to a Tactix 7 and was disappointed with how much dimmer it was than the 3. I figured it must be the touch screen functionality which I don't even use.

Hmm Fenix 3 HR had sapphire crystal but no touch screen or solar charging. I thought the solar was just the ring. Who knows....Fenix 3 HR was noticeably brighter. Anyway I want MIPs so 8 pro definitely won't do anything for me. Instinct 3 looks nice but I have Tactix 7 now so I'll stick with that.

I still use a Garmin Fenix 3 HR. I like the quick release charging adapter. I have it on a quarter turn mount that allows me to swap from arm to bike in seconds.

Good to know. I have a Polar H10 chest strap for workouts, so that will work. I had a Fenix 3HR YEARS ago when I didn’t know what I was doing, but for some reason, that watch helped me get into the best shape I was ever in. I think seeing all the data in one place, with context added, encouraged me to get after it more.

Fenix 3 HR, looks like I have the oldest Fenix so far. I bought it for my 30th birthday. I'm turning 40 this year and see no reason to upgrade.

I was recently in the market because I couldn’t find my watch, but I found it and I’m back in action and my Fenix 3 HR is still going strong. I definitely think you could get one of the older models that is still newer than that for well under 250.
