Is my Suunto 9 Baro Defective?

S9B seems to have an issue with the pace compared to A3PS

A stop is a stop for the Ambit 3. Not for the S9B. It’s jumping around and counting additional time and distance. I experienced it several times. For a correct recording of my activities I always use the Ambit 3.

i saw that also during moving time the pace is very kangarooish… this is for slower pace of course.
I need to check how it looks for faster activities once I can undust my bikes again

noticed this today and posted it in another thread (pros and cons of s9b) but thought it would be interesting in this thread, too

Thanks for sharing. It is interesting that Suunto 9 altitude shows more variation, and looking at the graphs I’d predict Suunto 9 to have more total ascent and descent. But in reality Suunto 9 has measured 110 m of ascent vs. 117 for Ambit 3 Peak.

Which altitude graph you think is more accurate?

that’s very hard to say for me at the moment… I need to figure that out over a longer timespan.
But in other threads I also said that eg MC routeplanning as a reference gives WAYYY exaggerated ascent values and SA does not show it during planning, only during navigation, but also there I think it is a bit too much on the plus side.
I will see if I can check with Gaia, Komoot or stuff like that.
Normally I don’t do a lot ups and downs… during winter: once up and once down

don’t know how to understand this: S9B goes in to the lunch break high and goes a bit lower after some time and A3PS is constantly gaining while I was sitting enjoying the mountain view and a sandwich

@TELE-HO I’m really hoping the next update moves the S9 accuracy closer to what was possible with the A3P.

For right now, if I have a route even moderately complicated to track the A3P comes with me every time.

@zhang965 @MC-Hall I think the major issue is the antenna. Ambits, S5 and Trainer (I believe) have external antennae that likely provide better satellite reception than the antennae in the watch bezel. There are many other factors as well, the numbers of satellites, reflections for GPS signals, etc. But in the end I ask, what do you need accuracy for? Is it for accuracies sake? If so, no wrist device will provide accurate GPS tracks, they simply cannot do this. I personally do not think any GPS watches will provide the pacing you may need for accuracy. A footpod is a much better option. My S5 does give me consistently better GPS tracks than the S9. I think the S9 tracks will be improved but I doubt most GPS watches can provide pacing and distance that is “accurate”. Fellrnr argues this same point.

Yes sir! Better explained!

don’t look at my comment about fitness level

I just wanted to update you with what we’ve discussed… ok, S9B received an update yesterday as we all know…
But I am surprised how precise this is on a (for me) almost flat terrain.
I should have taken A3PS with me, but I’ve had the focus somewhere else… sorry!
I’ll do that on Friday

GPS or GPS+GLONASS or GPS+GALILEO?

@vimegar
sorry… GPS only… this also effects FusedAlti of course
