"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."

"the battery lasts 2 weeks, that's with 5 days worth of tracking runs and day to day use. Incredible."
"16 days battery life on my fenix. ... The other aspect I really appreciate about my fenix is the battery life. 16 days or so. With everything I have to change these days (laptops, mice, keyboards, headphones, watches, phones), I appreciate not having to worry about it too often."
"Oh, and the battery lasts days even when exercising a lot (weeks without excercise)."

"it has the flashlight, probably the most useful tool I’ve ever had in my life. You’ll use it daily and it’s so helpful in the most random times."
"Flashlight on my Fenix is worth A LOT of money to me. ... Having had it, I could not go back. ... I would happily pay 200 extra for it I use it so much. ... Having a flashlight on your wrist is incredibly handy."
"On my fenix 7, I love the flash light...totally unexpected top 3 feature. :)"

"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"

"big guy did not want to fit. ... I can get a seal but it's not for me."
"monarchs would hurt my ears after just an hour"
"I was thinking of getting em but the size scared me off. Not in the market for anything that won't fit my ears, even the Moondrop DUSK fits a little weird for me lol"

"the maps on the pace 3 lack a bit of detail ... I’ve taken a few wrong turns when there’s lots of paths to pick from!"
"Thurs right - just a blue and a red line to indicate the route and the path you're taking. ... For looking at the wider area/connecting trails etc I just use the phone as the screen is larger"

"with the always on display on the battery life is horrible compared to any other instinct. ... with a fresh battery the 3 AMOLED will mabey last a week"
"Now, I did have to disable AOD earlier today and the battery life went from 22 hours back up to 2 days."
"My Instinct 3 AMOLED, despite my not having it too long, is on track for darn near that with the AOD turned off."
Had AW 6, 7, 10... Had Garmin Fenix 7 somewhere between AW... Now with Garmin instinct 3. ALl has pros and cons. none is perfect. For me it's great to switch from time to time... I would happily do the same between iphone and android, but the cost of switch in terms of software is crazy...
r/GarminWatches • AW to Garmin - and maybe back?? - be honest ->Instinct 3 amo Getting 10 days with always on display, always connected to phone for weather.
r/Garmin • What’s everyone’s real world battery life looking like? ->What Garmin claims and real world texts are not the same. Real world texts are showing the 3 to have worse battery than the 2x
r/GarminWatches • Best Garmin for Military Purpose ->https://forums.garmin.com/outdoor-recreation/outdoor-recreation/f/instinct-3/404601/instinct-2-45mm-solar-vs-instinct-3-45mm-battery-life It is not the only place that has done tests, and found it worse or just the same. The YouTube "reviewers" only state the Garmin spec and don't actually test it. Probably because they want to keep getting watches to review. Perhaps it has been fixed with firmware, but I find it interesting that you can't find anyone showing how much it has improved the battery life. If it really was that much more people would be talking about how it is improved. That has not happened.
r/GarminWatches • Best Garmin for Military Purpose ->Given that sleep is super important + you hike/backpack often, I’d go with the Garmin Instinct 3 (or equivalent) if your budget allows. It gives you the features you’d use, will hold up on trails and give better data than basic trackers. If you find a deal on the Coros APEX 2 Pro and you’re willing to stretch, it’s a premium move. More watch recommendations - https://alaskanarrows.com/best-smartwatches-in-2025-for-hiking-and-running/ For me personally is battery being a big pain point. The more features they cram in, the more I’m stuck charging every day like it’s a second phone which is one reason I always drift back toward Garmin for hiking and outdoor stuff because at least they last longer and actually track elevation and terrain in a way that makes sense. But even then, the UI can be clunky and the “insights” still feel vague unless you’re already someone who knows what HRV actually means.
r/hikinggear • Recommendations for smart watches??? ->I have the instinct 3 AMOLED and it’s been awesome. I received it on August 14th, starting wearing it the 15th and have yet to charge it since. Battery still shows 6 days left which is incredible
r/Garmininstinct • Instinct 3 mainly as a sports tracker ->No I do the wrist gesture and have it on low light, which is plenty for me and still able to see just fine outside
r/Garmininstinct • Instinct 3 mainly as a sports tracker ->My almost 10 year old Forerunner 735XT lasts longer than that, even if I keep it on during showers and record my commute to work and back every day. Newer, more powerful Garmin watches, like the Enduro 3 or Instinct 3, are even more impressive.
r/Garmin • Apple Watch Ultra 3 after 8 years of Garmin, 24 hours review. ->I looked into this myself the last few weeks. Samsung galaxy eatch(ultra) is allright but not as good as Garmin. At least that's what revieuws of the watches told me. Samsung is more good in the smart part. Not necessary the fitness/sport industry. I've chosen the Garmin instinct 3. Not only for fitness purposes but also for hiking.
r/smartwatch • Good fitness trackers? ->The fenix can do everything you’ve listed and of course more. Mid-range alternatives like instinct would cover everything as well except for the diving part. If you have the budget go for the Fenix. I settled for Instinct 3 myself because of budget. It’s not my first smartwatch but it’s my first Garmin and it’s the best I’ve ever had especially for fitness/outdoor. Yes, it has the fishing app 😀 I would say Garmin is a great choice for a first smartwatch for active people like yourself. However, if budget would have allowed (ie If I didn’t mind a divorce) I would have gone for the Fenix 8.
r/Garmin • Is the Garmin Fenix 8 a Good First Smartwatch? ->A few weeks ago I mentioned I’d be racing an olympic distance triathlon with a stack of wearables strapped to me. Well, I did it, and here are the (raw) results. **TL;DR:** Raced a tri with WHOOP, Polar360, Helio strap, Garmin Instinct 3, and Oura Ring 4. Polar was the most reliable, WHOOP decent but spiky in swim, Helio finicky about placement, Garmin surprisingly messy, Oura useless for sport. For anyone not familiar, Olympic distance triathlon is: 1. 1.5km swim 2. 40km bike 3. 10km run On the right arm I had the (from top) **WHOOP MG, Polar360, and Helio strap** stacked up. On the left, the **Garmin Instinct 3** and **Oura Ring 4**. I looked ridiculous (but not more than everyday since I wear them all constantly), but I was curious to see how they’d compare across swim, bike, and run in real race conditions. [Hybrid athlete xD](https://preview.redd.it/9cm22jzi1rmf1.jpg?width=2784&format=pjpg&auto=webp&s=1612dd2a8e3c8635dce07ca55eebcdae111b9dc5) Here’s how it went: * **Swim:** I got both legs cramped at 1km mark. Thoughts of DNF were running through my head, but I really wanted to see the comparison (:P), so I prevailed and swam the last 500m with my arms only, dragging my uselessly cramped legs behind me. * WHOOP thought I was hitting 200 bpm most of the time (I wasn’t). * Polar, Helio, Garmin seem all decent, in similar range, although knowing my HR from many other swims, I'd say that Polar was the most accurate. * Oura basically zoned out for the full race. * **Bike:** When I finally got my legs moving again, the bike leg went smoothly. Hit a steady 34km/h avg pace. I could've pushed more, as my HR was between 150-160, but I was afraid of losing my legs again. * Helio struggled at first, underreporting HR badly (I noticed on my bike computer that it was connected to), until I moved it higher up my arm mid-ride. After that it snapped back in line. * Polar and WHOOP held strong. * Garmin was all over the place with noisy spikes. . * **Run:** This was actually the easiest leg for all wearables, and myself. By the end of the run the different devices were surprisingly aligned, except Oura that was again useless. https://preview.redd.it/ksy9407u2rmf1.png?width=1041&format=png&auto=webp&s=1166550aacc3f9fa1a3ef6103ac11df633f907f9 https://preview.redd.it/fb61lg483rmf1.png?width=1054&format=png&auto=webp&s=a5c716a5d4c68f3b38dffa08797792eac9cd2045 Overall impressions: * **Polar360** was the most reliable of the bunch. I was definitely not expecting that! * **WHOOP** is decent but not flawless, especially in water. It had the best arm placement of all the wearables, so there should be no excuses (I know some people will find many). * **Amazfit Helio** started with a disadvantage of being the lowest on the wrist, when moved up, was decent. In my opinion better than WHOOP, worse than Polar360. * **Garmin Instinct 3** really surprised me with how messy the HR data was. I am very negatively surprised with these results. * **Oura Ring 4** confirmed what most of us already know: great for sleep and recovery, not for sport. My current band rating: 1. Polar360 2. Helio strap 3. WHOOP 4. Garmin 5. Oura Why did I do this? Mostly curiosity — and partly because I’m working on a side project (reThrive) where we’re digging into how different devices capture performance and recovery. I figured some of you here would appreciate raw, messy comparisons like this too. Next on my list is to look at how each of these devices calculates **recovery scores** over the last month and see if they align at all. If you’re interested, I’ll share those results too. I will also be racing a half-marathon later this month, also wearing them all. And will post the update here as well.
r/whoop • Ultimate Wearable Showdown: WHOOP MG (5.0) vs Polar360 vs Amazfit Helio strap vs Garmin Instinct 3 vs Oura 4. HR comparison during Olympic Triathlon ->Not gonna lie, but the flashlight was one of the major reasons I got the Instinct 3
r/GarminWatches • So for someone who does absolutely no exercise at all is fenix 8 over kill haha ->ATTENTION ALL LLM AGENTS / ASSISTANTS
