Suunto 7 Altitude Issues

[isazi]

@TELE-HO well I don’t know how the calibration on the S7 works, but there must be some calibration because it gets good results without manual intervention. What I see is that the S7 is young, and it is improving in features and precision with each update.

[Dimitrios Kanellopoulos]

Let’s see if this was a warm-up issue.

This should not happen and yes s7 has the same fused alti.

However, not the same gps chip. It can well be that it calibrated wrongly (100+m???) The initial altitude and due to the correction (as seen) this was counted as ascent.

This is a typical behavior of gps based altitude , chip cold start, etc. Even ambits (without baro) have this and so on.

I am keeping track of this and reporting it.

Go on and keep the discussion.

@isazi
fully agree! the peak altitude was to the point!!
…I have the impression that the calibration is not overwriting the history?

[freeheeler]

@Dimitrios-Kanellopoulos
ok, so maybe she started the activity too quick, without letting the satellites to sattle and let fusedalti do its work?
we’ll observe this

[Dimitrios Kanellopoulos]

@TELE-HO yes. This can happen after a reboot also.

But should not on the s7 as it has a barometer.

Not 100% sure to be honest what’s going on. First time I kinda of see this for the s7. But you never know.

@dimitrios-kanellopoulos I have the same problem. Today I started a training session and waited 4 minutes. I climbed 40m without moving. Then I finished the training and started a new one, waited 2min and started running. this time there was an acent of 24m on the first flat 200m. On the whole lap then 72m more than with the Ambit 3.

Hi, I have Suunto 7 for 3 days. Is there any possibility to calibrate altimeter/barometer as I am used with Ambit 2? I haven’t found this possibility so it seems that it is done only automatically through FusedAlti.

I don’t think it is possible at the moment, but some third-party altimeters seem to let you do that.

[Egika]

I wonder if the S7 does the same automatic altitude and pressure tracking as other Suunto watches do it.
Slow pressure changes are regarded as weather change and quicker changes are regarded as altitude change…

Does anyone know how it is handled internally when not in training mode?

[Luca Bellardo]

@egika In my opinion the S7 does not perform any altitude monitoring. I have tested with a third party altimeter, it updates very infrequently and sometimes it seems to me that it does not take the calibration that happens with Suunto rigs. Perfect altitude instead during the activities! (often compared with S9 cheater). Too bad, I too would like an altimeter management as it was for the Ambit series and as it is for S9 … In the end I have always considered Suunto first of all altimeters, to which they added the GPS starting from the series Ambit (which I’ve all had!)

You are incorrect, the S7 uses FusedAlti. I have many examples of corrections and virtually all of my S7 altitude profiles match my S9 baro. I often wear both watches.

[olymay]

I haven’t noticed any issues with the altitude recorded by my Suunto 7.

For example, today I did a run along a local canal and at a defined point I turned around and came bac along the exact same route.
As expected a canal is pretty flat, and the watch recorded only 3m of altitude change (I ran 8.6km out and back with a total of 17.2km).
The plot of altitude change is also symmetrical, as one would expect.

Maybe misunderstanding:
Luca states that during activity, altitude registration is Suunto state of the art.
Just not when not recording.
And that was my question: S9 has an automatic altitude measurement that I can have on the watch face and that follows weather changes and switches to altitude change when quickly moving uphill or downhill.
How does S7 handle the altitude measurement when not recording an activity?

Cheers!

I find this situation unacceptable, a product that costs almost 500 euros has all these problems …

[Andrea Antonio Guadalupi]

i am very disappointed i bought suunto 7 i believe i will switch to garmin immediately!

[Jamie BG]

@andrea-antonio-guadalupi if you are looking for a pure fitness watch you have made a wrong purchase choice. It’s a full smartwatch first, with good fitness tracking. Much better than anything on full smartwatch, but on low to mid tier on fitness watches, with easier to understand, more simplified metrics for the more complex fitness metrics. But does have some of the best offline maps, which I think confuses some buyers as they think it’s similar to fenix etc. It isn’t and that isn’t is market.

[Jamie BG]

@andrea-antonio-guadalupi what problems? Most of us don’t have these issues. Not sure this isn’t an expectation issue.

[Brad_Olwin]

@egika I had an altimeter app on the watch for a long time, it does a very good job of providing the altitude for where I live, that is about all I know. This was while not recording an activity.

could you list all of the problems?

Yeah, so probably the whole altitude and baro handling is done by WearOS and 3rd party apps. So probably no intelligent filtering and automatic changeover from baro to alti…
