Open water GPS drifting
-
@gerasimos
Of course, as I mentioned, I don’t have a major problem, but comparing my previous tracks from before the update, they look much better.
I think Suunto should investigate this.
-
I agree, same for me, since December 2024 GPS goes crazy as hell. Previously, I had not noted any problem. Let’s hope Suunto is aware of this and is working on a fix. I have let go the accuracy of this watch in the pool, but if this negative trend continues for open water swimming it will mean that the brand is moving away from supporting disciplines such as triathlon and swimming marathons.

To give an example:
-
I have one better. I started and finished within a few meters of each other, and swam in relatively straight lines up and down the beach, going down ~100m, back and so on. I know the distance because of the grounds on the beach, and can measure it using satellite maps…
If anyone wants to say ‘GNSS soak!’ I cycled for about 30m to the beach, and let the watch ‘soak’ for about 5m while getting ready. It had copied the bike ride to the watch before I swap, so it will have had opportunity to update the A-GPS.
This was with a Race, not a Vertical.
Then this was with a Vertical. Better… but for an out-and-back swim in calm water, not great.

@Ze-Stuart This is really crazy. Suunto, what happened to your devices…!?
-
@Ze-Stuart Exactly the same GPS behavor .
maybe @Dimitrios-Kanellopoulos can give an andvice

I should mention again that my brother has no problem with Ocean. Ocean’s last firmware is from December? So I would look for a problem somewhere after that time.

@Pavlas yes, I think as long as the firmware rollback also rolls back the firmware of the GNSS receiver I think we could have decent OWS again.

Can you share your pool swimming experience?
What do you think about the “new” algorithm?
What are your thoughts on swimming style recognition?Suunto Viper
Suunto HelO2
Suunto Ambit 3 PEAK
Suunto 9 Baro Titanium
Suunto Vertical -
or if anyone try to use the support chat in the Suunto app to find a sotution for this issue.

What are your thoughts on swimming style recognition?@Artus-Diver Swimming in the pool is the most poorly designed activity in SV in my opinion (I also do other sports, so I have some reference as to how SV performs in other fields), nothing here works well. I don’t know if there is a new algorithm, but style recognition is worse than it used to be (about a year ago). I’m not developing the thread here, because it would be off topic, but through my profile you’ll hit the posts where I write a bit more. Generally, they boil down to the fact that I don’t have a good opinion about the SV measurements quality in the pool, and I’ve stopped hoping that it will get better. Although swimming is one of my preferred activities. I feel even more disappointed when, in addition, recent updates have broken SV functionality in open water swimming. I also reported the similar issue with snorkeling in December, it’s all about the GPS signal, I guess. After all, it all worked well, certainly a year ago.

@Ars-Vitae check this reviews for openwater
before and after uptdate
very good gnss

To save others a trip down memory lane:
Now, we move on to openwater swimming. I’ve done a lot of openwater swimming with the Suunto Vertical – and frankly, none of it is good. In fact, it’s all horrifically bad. On present firmware, the unit has yet to complete a single one of nearly half a dozen openwater swims without failing halfway through. Essentially, if I tread water for even a very short timeframe (such as waiting for my swim buddy), then it’ll lose GPS permanently for the rest of the swim.
Bold is my addition.

I’ve just downgraded to FW 2.40.44 as the GPS drifting during OW swimming is quite annoying in 2.43.12. The previous FW was better, according to my experience.
