Fenix 6X Sapphire! Works really well in open water. In the pool, it may lose a lap here and there but I've never lose more than 4 laps in a 3000 yard swim.

I have Fenix 6x Sapphire and it's amazing for multi sport. New watches just came out, so anything lower than the 8 is going for less on the used market.

My Fenix 6X Sapphire is awesome for all the tri sports and more. You can get them at time under $500 now.

Garmin Fenix 6 and 7 are having some hot deals right now. Go Sapphire for the extra protection. But if you only need the bare minimum, Forerunner 2xx

why not both? if you get like a Fenix 6 used then you can also get a Garmin 130 Plus for the bike. I use my watch for the overall measurement, but the 130 allows me to have a screen in front of me (I don't sync the bike computer to my workouts).

Not required, unless you plan to make it a lifestyle. Then you need to plan accordingly. I have a Garmin Fenix. My view (just for me) is that I want a sports watch with smart features. Not a smart watch with sport features.

I went from Fenix 6x sapphire (51mm) to forerunner 970. Got sick of how heavy and clunky it was and I’m a bigger guy.

I think Fenix 6x Sapphire was peak Garmin.

Fenix 6x Sapphire. 51mm. Built like a tank. Reliable. Durable. Still great as a fitness tracker.

Yep, AWU2 and Garmin Fenix 6X sapphire. My AWU2 is my daily driver, use it for most things up to and including short 10km hikes, short workouts, etc, however when I do a longer hike or I want to record more health metrics ( I prefer the Garmin fitness metrics) as opposed to just having the smartwatch functionality, I’ll wear both watches and use my Fenix to track my hike, map my route etc.

I was just about to make my own post asking about this! Currently running a Fenix 6x Sapphire, had it for about 4 years now. Mainly used for running, cycling, gym, and the occasional swim/hike. Connectivity to my Wahoo Smart trainer is a must. I almost always wear a chest strap (Polar H10) as the watch HR is unreliable as fuck. What would I lose moving to one of the newer Forerunners? And conversely, what are the benefits of upgrading to say a Fenix 8? Thanks
