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.

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 got a Felix 3 in 2018 that I replaced earlier this year and it was still only needing charges weekly, maybe twice a week if I did some real long bike rides

Garmin user since the Fenix 3HR and I don’t know where the hate is? Are we sure it’s not bots lol? Everyone I know in real life loves their garmin and through the years I’ve gotten at least 9 other friends and family to get Fenix’s or Descents. They all love them. Nothing comes close to durability, battery life and sheer amount of data and options. A lot of times the “chatter” online doesn’t equate to what’s happening IRL. That statement applies to most things in life.

I have had 2 Garmin watches (fenix 3hr and Fenix 6)in the same time my friend has had no less than 5 AWs. The build quality is unbelievable on Garmin and the battery makes Apple look pitiful. 2-3 weeks on a charge. I forgot I had my fenix on and did a mud run. Didn’t even phase my watch. Literally dragged it through the mud and it just kept going. Apple Adds a good product but Garmin is next level.
