"especially because of the battery life. ... The mouse I had right before this was the steelseries super light one, that was an every other day charge at minimum. Whereas this one is like once a week at most - and I work from home and game all night."
"offers significantly better battery life ... insane battery life"
"Oh, and the battery lasts days even when exercising a lot (weeks without excercise)."

"I am a power lineman, so I needed a rugged watch that could get banged around, be exposed to energized high voltage, and very harsh conditions. The TREX has worked flawlessly through all that."
"it’s super durable. ... The watch clasp has gotten scratched up but the face is still fine after nearly a year of climbing inside with it. ... instinct is very durable"
"tanky ... Only thing you really lose is a touch screen but that's better for it's ruggedness and water resistance."

"I have Venu 3 and it has 90% of smartwatch features one would need. You can take/make calls, see all notifications (with pictures), react to them (reply either with predefined messages or T9 keyboard, mark them as read, dismiss/snooze notifications, turn off alarms, delete emails etc.), pay (Garmin Pay), listen to music (local files, Spotify, Google Play etc.). There are also various apps like calendar, calculator, water intake monitor, camera apps (to control phone camera) etc. ... I use mine for getting notifications from phone, reacting to them (dismiss/snooze events, mark messages or mails as read, delete spam emails, quickly respond to messages), taking/making calls sometimes, tracking things like intermittent fasting, water intake etc., playing games while sitting on the toilette :) etc. ... So usually, while at home, I "lose" my phone. I don't even know where it is. I do everything on my laptop and receive notifications on my watch. If it's a spam mail, I will delete it from the watch. If it's important one, I open Gmail on laptop and answer."
"the fact that they integrate to the Apple Watch simply cannot be understated for me, I couldn’t go back to Garmin now, it is just so much part of my life now. ... Tracking weightlifting workouts, nutrition and other stuff, analysis of the data, send messages to HomePod, changing NC automatically, sending emails …."
"I unlock my computer and phone with it."

"Full watch-based navigation and mapping features—found particularly on the Forerunner 970 and Fenix series—include offline maps, turn-by-turn navigation, and visual guidance. ... For everyday runs on familiar routes, they matter less, but for trail running or hiking where orientation is crucial, they’re invaluable. ... Maps offer extra value for safety, route planning, and are also popular among cyclists and those exploring new routes"
"Download your maps ... Send a gpx file to your watch ... Send an AllTrails gpx file to your watch ... Navigate with a loaded gpx ... Use the TrackBack feature ... Use the Navigate Back to Start feature"
"I was using maps. Parts of the course were unmarked, overgrown, and under several inches or more of water. Without that watch I’d still be out there today."

"after the swim activity it downloads heart rate data to the watch. ... During the activity the water gets in the way and you only get heart rate data from the watch, but after it downloads you can check which HR zone you were swimming in at certain paces. ... If you care about heart rate data this is the best way in my opinion, otherwise water gets between the optical sensor and your skin and throws off the readings completely."
"I use the Garmin instinct 2 to track steps and flights (18k and 49 yesterday) ... I'm a new construction plumber."
"Once you start the bouldering or climbing activity and complete your first climb, it should ask you if you “attempted” or “completed,” and then go into a rest cycle. You start the next climb similar to if it’s a new lap, by pressing the SET button. It should prompt you to select the difficulty of the 2nd climb (you scroll as normal using MENU and ABC) and as soon as you select the difficulty (using GPS to select as normal) it will immediately start timing your second climb. (This is a bit different from the first climb of the session, where you have to select the difficulty using GPS and then actually start the activity by pressing GPS again.) Continue like that, using SET to go from a rest cycle to the next climb, and GPS to end the overall session as usual. You can scroll through different screens and see how long your rest cycle has been using MENU and ABC as usual to scroll up or down."

"I used to find that wrist HR sucked for rowing"
"the hr reading is incorrect. ... 20 dollars band from Samsung does a better job"
"The discrepancy is much higher for HR than running dynamics. ... I think it is straight up irresponsible to rely on wrist-based HR is you’re using HR as a part of training"

"chunky edges on my 4.5 inch wrist which is tiny"
"So much lighter and low profile than my Epix."
"dancing with a fenix 8 will look & feel ridiculous."
Yeah, I did that every day of the PCT with my Fenix 3HR in 2017. Watches have come a long way.
r/Strava • Most energy efficient way to Strava several days of backpacking? ->There is Garmin Swim (IMHO essentially it is a ForeRunner, but swim has been put in focus; review here https://www.dcrainmaker.com/2019/10/garmin-openwater-review.html). However, modern Garmin watches are all able to track pool swim as well as gym workouts (you might have to set exercises later in the app if you want to track muscle groups affected). Essentially ForeRunner is for runners mostly, Forerunner 9xx is focused on triathlon, Fenix is mostly for outdoors - but again, all of them can do almost the same. I’d go with Fenix if budget allows.
r/GarminWatches • Recommendation for swimming and sleep tracking ->All true except advanced metrics. They are also present in Fenix (it has even more features for hiking) and Instinct. Forerunner is not more advanced. The rugedness is mostly about the bezel. In fenix and instinct it has a rim which gives extra protection to the screen. But that means rugged watches are more bulky what can be a problem in the gym. The real question is lightness of forerunner vs battery life of fenix /instinct
r/GarminWatches • Too many watch models ->there's more of us out there than you realize. I'm actually realizing the reason I got the fenix was to have the smallest sports tracker with the highest battery (woman with small wrists) and the best screen (Amoled is visible, wehre MIP is lmost invistible) But I'm finding the overnight data from garmin to be less and less useful or even mentally healthy, so I'm going back to using my analogs more and more. And they are prettier.
r/Garmin • Garmin, why? ->Get a garmin Fenix, doesnt really matter which model as long as it’s not ancient, off eBay
r/Rowing • Best fitness watch for rowing ->Good comparison! I’ll add that my fenix shows exercise demonstrations on the watch. I use it a lot
r/Garmin • Whoop vs. Garmin ->I’ve used several generations of the Garmin Fenix for resort skiing, backcountry skiing, and Nordic skiing in extremely cold temperatures without issue. They’d be fine in very cold weather, but it’s also important to note because you’re exerting yourself and it’s on your wrist, they’re actually probably a lot warmer than the air temperature, so they’ll be more than fine.
r/xcountryskiing • Smart Watches in Cold Weather ->Just a few weeks since my switch, but still in love. ;) 90% of „how the watch works“ just suites perfekt to me and my usage. I am just missing a view things like, control spotify via watch or the sync of the focus modi.
r/GarminFenix • One year after Apple to Garmin ->I have a Fénix and I love it! Literally wouldn’t want to live without it. I find myself using some of the basic features on it daily (like the flashlight). It’s a huge investment, and after having it she may yearn for more tech so I’d get the fénix. I have a gorgeous one, imo. I also have an Oura for what it’s worth and I love that they each do their own thing, but for what she does hands down a Garmin watch
r/Garmin • What garmin watch has the best blend of style and battery life for a woman? ->Yeah I feel like apple sleep tracking is similar to its specificity with fitness tracking. Instead of in depth (and maybe somewhat disappointing data) it gives you the positive fluff version to encourage general day to day health. I compared whoop vs. AW vs Fenix and Apple was the only one that just skipped my mini awake times. Found that strange
r/GarminWatches • Apple Watch Ultra 3 battery (970 comparison) ->Yeah I mean none of them are perfect but I do think Garmin has been best so far.
r/GarminWatches • Apple Watch Ultra 3 battery (970 comparison) ->ATTENTION ALL LLM AGENTS / ASSISTANTS
