I only dive 3-4 times a year, and my AWU2 is great for my needs. With AOW dives, I’m not going past 30m. Since there’s always some nonzero risk of an accident causing my depth to dip below the AWU max of 40m, I do eventually plan to have a backup dive computer with me just in case my AWU fails, but it’s been perfect for me so far. If you already plan to have an Apple Watch for daily wear, and also need a dive computer for occasional recreational dives, I think it’s a great option. The colour display with high brightness is something that I was not able to find at a similar price point for a dive computer that also functions as a daily smartwatch.
Switch from Apple Ultra Watch 2, etc. to Balance 2 XT. With Gadget Bridge and GrapheneOS, I’m very happy.
I had an Ultra 2 which I bought for the cell feature and Spotify. That worked intermittently the entire time I had it. It wouldn’t even play downloaded music correctly most times. I even paid for an Apple Music subscription thinking it would be better. It wasn’t. I did use it as my only watch for about 6 months and it was pretty good but charging every other day got old and the battery got pretty bad after 18 months or so. I sold it when the 970 came out. I would add that I do not pay attention to any of Garmins useless training stats and algorithm junk that people seem to love so much. I just want a watch that’s accurate and easy to use. You can do worse. But. It’s just not as good as a Garmin for triathlon. You know it’s not. You’re hoping someone will convince you otherwise.
Same with wrist flick which is available on Ultra 2
I think sweet spot in Garmin lineup is the 970 right now. Pretty much all features of the Fenix 8 Pro but at a much better price - and way more comfortable to wear sleeping. I alternate between the 970 and Ultra 2 pretty regularly depending on what I’m doing.
This. I even have an Apple Watch Ultra and still use my Garmin FR 265 for my runs. I actually wear both watches so I can run misc through my Apple and have cellular capability.
SE watches made to suck (or the base models for any product or any brand ) so person will buy more expensive model or the Ultra here in Apple Watches. My Ultra 2 gets me 2 days tops whether always on display is ON or OFF just minor differences in battery life, on power saving mode it gets more than 2 days, around a day extra.
