Pros/Cons of Suunto 9 BARO * ONLY * be fair and polite!

@TELE-HO I think it is at least two weeks but it seems better than that. I have two S9baros (don’t ask) and if one is not connected to the phone or tracking anything I am fairly certain I can get a month out of it.

But my charging solution was to simply buy another cable and put it in my car. I have a 40 min one way commute to work. Charging the watch while I commute once per week is all I need, plus if I am going on a very long weekend run I can charge on the drive there and be in good shape. For me as long as I get a few days of charge I am fine so I usually do track HR and track sleep.

I tested route planning, sync and navigation yesterday. works great! I’m looking forward for vacation end of next week. I don’t have to prepare a hike or two that we might want to do already at home. I can do that spontaneous on site

I am flying home from Europe right now where I was at a meeting. While enroute to Europe, I planned 3 different runs in Copenhagen after looking up where my hotel was. It was so easy to use the heat maps and I probably mapped out about 10 runs just to see how long they were. I wanted one 10k, a 15-18k and a ~22k route. I synced them all to my watch and was ready to go when I got there. All I can say is the route planning on SA is the best on any mobile app hands down. Kudos to Suunto for their implementation of that.

I tested today S9B vs A3PS in direct comparison on a family “hike” with a lot of playground and icecream pitstops…
what I notice is that A3PS has a calmer recording. I saw couple of times while just sitting in the sun (I did not hit pause by purpose!) that S9B keeps showing some speed and adds up distance.
In the end S9B recorded 5.27km and A3PS 4.8km which I consider more realistic. I think this is cause by FusedSpeed?!
Normally I don’t do so much pauses, so for me nothing to worry about.
When I look at the recorded track: yes, A3PS has better accuracy.
And for me the most important value was total ascent: it is a more or less flat topography and S9B recorded 110m while A3PS recorded 117m.

Here are the links:

and here’s the link for direct comparison of the track.
…and if you go into the graph you can clearly see that S9B seems to have an issue with the pace compared to A3PS. of course I did not press pause for our pitstops… but you can see pitstops in A3PS pace and S9B is just spikes… also during the entire activity…

apart from that: awesome tool @Dimitrios-Kanellopoulos

I live in a neutral country, I just say what I see

from scientific point of view there is nothing wrong to check and compare the truth.
Ok, it is not a representative analysis… this might take a bit longer.
But it’s nice to have two watches and to check and verify what’s discussed in here.

here’s another comparison of S9B and A3PS. Both watches in performance/Best GPS mode and GPS only.
Both tracks have some offsets on different sections.
During the pauses (they were quite short this time and pause button was not pressed) the watches did not freak out and started counting unwanted distance. S9B showed – in pace field during the my pauses while A3PS showed some min/km.
I see that S9B still has some pace spikes during the activity and A3PS had one major pace spike. But it’s not as bad as with my last test. This is by the way not visible in Strava and SA. QS is very precise in this case.

I think the best improvement is the total ascent. My activity was one big climb at start and then one slightely interrupted descent and then rolling terrain until the end. 7m difference is about 1% and more than acceptable for this type of profile in my opinion.

And another one. A stop for the Ambit 3 is not a stop for the S9B. 4 minutes difference in moving time is not okay. And the difference in the ascent is not okay too. I recorded the ride additional with an Amazfit GTS and the results are quite close to the Ambit 3. Astonishing.

I think you face the same problem as I do with the S9 Baro. The speed wobbles a lot which, in my opinion, is due to a bad signal reception or GNSS algorithm. This adds some distance to the total track

@surfboomerang
I see that it has improved. The distance is reasonable and differs minor to the distance of A3PS recording.
It was an issue, it has improved. If it is good ebough, I will check in the next month with slow moving activity on skis.
But for me it’s going absolutely in the right direction

freeheeler

@pilleus agree, your recording of the alti graph looks a bit worse than mine.

I think we must not forget that also sensors have tolerance.
I’m by far not a top athlete but from my personality quite demanding. For me it’s fine as it was today.

@sartoric I am rather late to join the visibility part of the discussion. For me I more or less solved the issue by simply switching the mode under options to light, also that I have dark numbers on a light background, which improves visibility (for me) vastly, even when the backlight is inactive and the sunlight no longer / still not that bright.

… just compared my wifes and sister in laws half marathon track recordings from last week.
one A3R and one A3PS.
Both are a bit offset… and from a distance it roughly looks like same accuracy as S9B…
every device receives satellite data and calculates individually… this makes me think that it is nice to compare A3PS vs S9B directly but we should not judge too critical…

… I mean… please correct me if I’m wrong, but the satellites are located more or less half way to the moon… 1m accuracy is like if you would want to shoot a football from the moon into a goal in whatever stadium, isn’t it?!

Yes, it is. And in all cases the tracks of the Ambit 3 are better. More accurate, more precise.

freeheeler

@pilleus
but when I checked A3R vs A3PS they also differ… it’s hard to quantify but it is a measuring system and it has tolerance. That’s my point of view.

here are two tracks of the same skitour, both with A3PS… first how it should be, second when recording is crap… even A3PS hast its weak days

edit: if you follow the second track you’ll fall over a not insignificant cliff…
