"if you have to take your phone anyway, there's a much better device on you for making calls. ... apple watches can have sim cards and place calls *without* having your cellphone on you. that's a real use case -- go for a run, leave the bulky phone at home."
"Garmin is only a smart watch in terms of activity tracking, the true smart watch features are rudimentary and rely on your phone being close by."
Yeah as he said not an insane sale but a reasonable one. The mapping is nice and the battery lasts a long time. (finished a 100 easily with it)
r/Ultramarathon • Simple watch - long battery life, pace, and GPS ->nah not 945 ha, i upgraded from it to the 970. So much better in every way, especially the quality of gps tracking
r/GarminWatches • Forerunner 970 or Fenix 8? ->The forerunner 945 is on sale here https://www.walmart.com/ip/Forerunner-945-GPS-Running-Smartwatch-in-Black/219688585?athbdg=L1600&from=/search I love this watch.
r/Ultramarathon • Simple watch - long battery life, pace, and GPS ->Weird mine lasted me for the full Hennepin 100 so 26 hours
r/Ultramarathon • Simple watch - long battery life, pace, and GPS ->I have been a Whoop wearer for 4 years. I have had a Garmin 945 for 5. This is exactly my use case—run and strength (and whatever else) with the Garmin and whoop for the overall experience.
r/whoop • Running watch just to run ->Garmin Forerunner. I have the 945 and it still going strong. Does a great job with running, swimming and biking. Add in a Garmin Edge eventually for your bike. I do know several people that are quite happy with their Coros though. Not sure what they offer for cycling computers though.
r/triathlon • Which running watch to buy? ->Can't speak for the Instinct, but I got my Garmin Forerunner 945 in 2019 and it's still going strong. Passive battery life a week+, GPS battery is still close to 24h (I think, haven't done a race that long in a bit). No issues with connectivity, bluetooth, charging, nothing. Some of their newer models are a little bloated and they're adding a ton of features at the cost of battery life, which is the only disappointing part. For ultras the only thing I _really_ care about is battery, and their out of the box battery life says 26 hours or something now, instead of 32+. Either way though, they make really good devices.
r/trailrunning • I have to choose between the Suunto Race 2 and the Garmin Enduro 3. ->Yep, great watch. I've had mine 12 months now, and I ocean swim about 4 times a week, plus trail running and MTB. Does it all, very nicely integrated on Apple devices.
r/Garmin • Pool swimming killed my Apple Watch, now I want to switch to a Garmin ->This must depend on your model. I often use the buttons of my FR 945 while swimming (usually because I forgot to start the activity!)
r/Garmin • Pool swimming killed my Apple Watch, now I want to switch to a Garmin ->I have garmin forerunner 945. I really like it and it is great for running as well. I can also listen to music, podcasts etc. You can find deals sometimes so that it might fit in your budget.
r/Kayaking • GPS watch for kayaking? ->How quickly does it charge? I've gotten used to popping my Garmin (FR645, FR945, Fenix 7s, then Fenix 7s Pro) on the charger for 10min or so while I shower and that is enough that I never have to worry about the battery. Think the same would be true of the Venu 4?
r/Garmin • Finally, Venu4 is here ->well, the 945 is now 3 generations old so I'm honestly surprised it's come up that often to even make the list. I have a 955 and i feel like it's dated being 2 generations behind now. I'm more surprised the 965 isn't on the list. Maybe 945 is there because it can be had for cheap if buying used?
