Get the mk2i or 3i if you’re into diving. The dive computer is on par with the best tec dive computers. I’m an instructor and my mk2i is always on my wrist
r/GarminWatches • Which Garmin is for me? I do a wild combination of outdoor sports. ->For sure! I haven’t used it for diving in a year and I’ve been using it for everything else. It’s great! It has maps and other features when you’re doing other sports. It has everything all the other sport watches have… just also an amazing dive computer! If I’m doing an all day activity where I have it tracking me the battery might loose 25% a day. If I’m not doing too much it’ll last ~ two weeks
r/GarminWatches • Which Garmin is for me? I do a wild combination of outdoor sports. ->I currently use a Garmin Descent Mk2. It's basically a fenix 6 that has an integrated SCUBA computer. The sensors and software are the same as the fenix 6 series, and I get great data from my swims with this.
r/OpenWaterSwimming • What GPS watches are you using to track your swims? ->I have a Descent Mk2, purchased 2020. Survived a motorcycle crash (direct hit, according to the bezel scratches), extreme temperatures, ocean water, hot springs, you name it. No issues. Battery life has gone from a solid 14 days to maybe 10.
r/GarminWatches • Question on longevity of Garmin Watches ->>I had the mk2i and upgraded to the Mk3i. The flashlight is amazing for getting around the house at night or finding something under the couch. I use it to get dressed for runs in the dark and not wake my wife up lol. Also BATTERY LIFE.
r/Garmin • Which Garmin watch do I need for fitness tracking and SCUBA diving? ->Had the mk2i for a couple years as my daily driver, the thing was absolutely bulletproof. I was a stone mason by trade and that watch kept up unbelievably well. Dove with it several times and loved its simplicity with the garmin dive app. When the mk3i came out, I got it and gave the mk2i to my 18 yo nephew who is probably harder on it then I ever was! I’m 100% sold on the durability of the design, and I love the always lit up feature of the mk3i, not to mention the 11 day battery. Not sure what they’ll have to do for me to upgrade next, but I’m totally here for it. The new Fenix’s have a pretty legit depth rating now as well.
r/Garmin • Which Garmin watch do I need for fitness tracking and SCUBA diving? ->I have the Garmin Mk2i and it is awesome. I run, shoot, fish, snowboard, hike and swim. The Mk3 is only better. The dive computer rocks too!
r/diving • Is the garmin MK3 good for me ->My Garmin has been accurate. I have an mk2i because I also dive, but I learned the swimming features from a you tube video teaching a Forerunner. The software appears to be the same. My watch is most accurate when I complete lengths without stopping. If you're stopping in the middle of a length to do something other than swimming, I think you're going to get poor accuracy. But if you punch through your lengths wall to wall it will be great. You mentioned ecosystems. Trying to upcharge folks that might feel somewhat locked into an ecosystem is unfortunately de rigueur on Wall Street. Apple is doing it and that sucks (my wife is locked into their ecosystem big time), but Garmin is doing it too. They've introduced subscriptions to Connect and Explore, two of the Garmin apps my device uses, in the last year. They're easing into it, and people are complaining, so hopefully it doesn't get too bad, but when you're comparing Apple to Garmin I wouldn't give one company the advantage over another in terms of treating customers well who have sunk costs in the ecosystem. As a Garmin owner obviously I hope to be able to say something different in a year or two, but for now my opinion is that they're both trying to screw people over. In the meantime if you're you're concerned about ecosystems I've heard Suunto is finally back in the game and treating people right. I haven't run one since the '90s, so I can't give advice, but maybe do some research on that if ecosystems are a big concern.
r/Garmin • Does Garmins track swim laps as good as the Apple Watch? ->I have the Descent mk2i. I love it, but didn't have one before this so I didn't have a comparison. Just having a dive watch made a massive improvement to my time in the water. Only regret I have is getting the i model thinking I'd use it scuba and the wireless tank connector. Alas, it's been 4 years and not used it once for scuba lol. So have a good think about what else you want or if it. Otherwise, the device is fantastic. Has maps with GPS for when I'm doing drift diving or hiking, And of course all the other standard Garmin watch apps (running, weight lifting, rowing, wallet, music, etc) Battery life is great too!
r/freediving • Which watch is best for freediving? ->I bought a new mk2i a year ago and love it. SOOO much better than my Fitbit Charge 6. mk3i really only adds 200m vs 100m diving depth. if you don't need air integration, the non-'i' versions are considerably cheaper, or you could get a Fenix 8 and have all the latest fitness/sports features with amoled and touch screen with diving to 40m (enough for Rec diving)
r/Garmin • Which Garmin watch do I need for fitness tracking and SCUBA diving? ->I had the mk2i and upgraded to the Mk3i. The flashlight is amazing for getting around the house at night or finding something under the couch. I also enjoy the AMOLED display more, and the case is a millimeter thinner which makes a big difference. The mk2i is no slouch though if you are concerned about price. Maybe look into health insurance discounts or student discounts. Both offer 20% off.
r/Garmin • Which Garmin watch do I need for fitness tracking and SCUBA diving? ->After owning several Suunto dive computers, I’d recommend looking elsewhere. They are fine computers but they’re overly conservative and their custom service is atrocious. They also had several hardware issues with some of their console computers that left a bad taste in my mouth. For what you’re looking for, the Garmin Descent product line would be a better match.
