Absolutely the best Garmin watch

I ran more than 3000 miles per year and have plan in future for triathlons. Fenix 8 Pro is absolutely the best gear. I bought the 51mm version for the longer battery life but you won’t regret with other smaller versions

Great Multitool Watch

I've had this for a little over a month and am very happy with it so far. My primary use cases are outdoor ultrarunning, strength training, cycling, and climbing. I upgraded from a Fenix 8 to get the LTE/Sat connectivity, because I dislike running with my phone.
Overall, this watch has been superb. All of the "base Fenix 8" aspects have performed flawlessly; I will focus on the "pro" aspects.
On LTE: LiveTrack has been working flawlessly. The LTE messaging has been working well, also. One note: When somebody replies to you, sometimes it doesn't come through right away (such as if the watch is getting its internet connection through a phone); hopefully Garmin will fix this latency issue. I have not used the satellite messaging feature yet.
On the size...The 51mm model feels a little large, and the pro version is a little thicker than the base Fenix 8, but I got used to it and don't mind it. I opted for the larger size to have sufficient battery life on longer runs when using LTE and navigation, and so far the battery performance has demonstrated well.

Great watch

Bought this watch over a month ago and am so far enjoying it. I have finished some long rides and a half Ironman without any glitches. I have not subscribed yet to the inReach subscription plan so cannot comment on that but I have to say that the original Livetrack is not very consistent and does not always send message to the recipient when activity is started. I have researched in forums but could not find a clear solution. Garmin needs to work on this. Other than that I am yet to explore all features but it was a great upgrade from my prior Fenix 6 Pro to this one.

I’ve had this watch for 3 weeks but it’s my fourth generation of Garmin watches. I absolutely love this watch and the previous fenix and forerunner versions I’ve owned. Superb battery life and relentless number of features. I’ll never give it up. Love tracking all my stats.

It’s a great tool

I was gifted an Fenix 8 Pro 51 for Christmas and lucky enough to get it early, so Iv been wearing it for about 3 weeks.
Coming from an Apple Watch Ultra for me there has been a learning curve. With that being said I couldn’t be happier with the switch. Tracking is great. Garmin Coaching plans are amazing and hard and push you. The mapping features are second to none. Haven’t used the inReach features but haven’t had the need to. In testing they seem flawless.
Does everything I need it to do and more well worth the switch.

So far ... so great!

I needed something with a longer battery life that would allow me to track iterative, all day hikes, like on the Appalachian Trail. I considered the Fenix 47mm Pro, but a few $$$ more, I could almost double the power with the 51mm Pro. Preliminary test hikes, using auto select, utilizes about 10% of the watch power for a 10 mi / 6hr hike (which collects all the metrics), and is about what I expected. It's a baseline, but I need to research / know & test what metrics can still be collected with more battery efficient gps / tracking settings. My other activities (cycling, running, walking, strength, HIIT training) and metrics will just be bonus. Also, love how the health and sleep metrics that are collected and summarized graphically and textually by Garmin Connect. Still need to test other settings and scenarios, including the subscription plan (but I have the Inreach Mini 2, so somewhat familiar). Integration to Strava is automatic and immediate.
Pleasantly surprised how well the 51mm wraps around my (only) 18.3 cm wrist. Love the Titanium bezel, sapphire lens, & watchface variability! The reports (e.g. weather, stock, sunset, etc), compass, and flashlight are bonus. Overall and so far (two weeks in), completely satisfied! Well done Garmin!

Great features, tough watch

I purchased this watch about a month ago. This was an upgrade from the Fenix 5 sapphire. My previous watch was solar so I really enjoyed almost never having to charge my watch. Thankfully this watch battery seems to last at least a few weeks before needing a charge. Also I didn’t even realize this watch is touch screen as well, great feature update. The screen is much brighter and clearer. Still exploring all the features, there are many! Overall a great fitness and activity tracking watch. I’ve had a couple Apple Watches and they don’t even compare to Garmin. Definitely recommend!
