Long battery; but wrist HR tracking is inconsistent.

Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
Garmin swim 2. Gives you pretty accurate yards that you can see while swimming. My Fitbit charge wouldn’t show distance until I stopped and synchronized with my phone after. Also, wet touchscreen on the Fitbit is useless.
Using Garmin Swim 2. Happy with its function for tracking laps in indoor pool, took a little getting used to for accuracy. I have to be deliberate and smooth on my turns. Original band was tight on my large wrist, larger band was expensive, around $40.
I stopped using my Garmin Swim 2 because it would routinely add or subtract a lap or two on auto lap count. Maddening.
Plus one for the swim 2.. It's a basic watch that really only does swimming but it does swimming well. Both in the pool and open water. I particularly like that there is no touch screen and it's all button operated. Touch screens in the water are the devil.
I've had a Swim2 and upgraded to a 265 (which has a better accelerometer). Stroke detection probably won't get much better with an Apple. My watches sometimes confuse sprint free and fly, but otherwise it mostly gets it right. I find stroke detection matters a lot less than being able to count laps anyway. Auto lap counting on all watches is about the same.... all are 95%+ but if you want 100% you need manual stop/start and only Garmin has that
Don’t insult my push offs like that. Just kidding lol. I’m still getting used to the watch and absolutely use the auto interval feature. May just need to turn it off! Seems to be the advise
Ohhh yea I have that issue with the garmin 2. Meaning, I can’t go back in and edit it once it’s complete. I wish I could do that purely because I don’t know what workout I’m doing until I’m in the water and the coach tells me what to do
This is my issue. I want out of the Garmin ecosystem altogether. My swim2 routinely adds an extra 25 and I'm not doing anything strange. I do hit the lap button to mark the end of a stretch. I don't have hope that a different Garmin will be better since it's most likely the same code under the hood. I loved my apple watch until I busted it. I'm considering replacing it but I'd love to leave the Apple ecosystem behind as well. I'm really stumped on finding a replacement that will match the apple functionality. I don't think it exists.
