Suunto 7 Altitude Issues

[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.

@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.

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 …

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

@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.

@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…

I think so. Since I installed Alti-Barometer app with automatic altitude calibration the altitude reading and ascent are great. Start and end altitude are correct and ascent and descent too.

But in Ghostracer I must calibrate the barometer even if the Alti-Barometer app does it before.

@pilleus alti-barometer app???

@pilleus I tried the application, but the altitude is completely wrong sometimes …

I cannot solve the problem. With a run of 400m ascent, the S7 shows between 100m and 200m more ascent compared to an Ambit3 and an S9. There are always short spikes down and up that are wrong. I had the watch at service and was told that the sensor was not faulty.
The S7 is dark green

[Brad_Olwin]

@kurt68 It appears that something is temporarily blocking the sensor holes, either you skin or fabric.

[Kurt68]

@brad_olwinI can exclude clothes I paid special attention to that. If it’s the skin that’s a problem, I can’t change anything? It can’t be dirt. The watch was just at the service.

@kurt68
Suunto Core, Suunto 9 and Suunto 7 obviously have this issue.
With S9 and Core it does not matter so much as you have either no HR at all or you can but on the chest belt. With S7 I consider this as an issue, since OHR requires a proper fit on the wrist.
IMHO it is a design flaw that can happen to all designers. Let’s hope Suunto improves that for their upcoming baro watches. I would have ideas… but @cosmecosta and I are still fighting who’ll get the job

[cosme.costa]

@freeheeler I thought that we agreed to be collaborative .

Now seriously, I see the issue but I also see advantages to the actual design. This design is also used in some Spartans without many complains (the Ultra has different case but same position for the holes and Spartan Sport with baro has the same case). I also remember @Dimitrios-Kanellopoulos commenting that A3 peak had also some downsizes regarding the baro design, but he didn’t commented which ones.

@Kurt68 have you tried to use the watch in the other arm?

[Kurt68]

@cosmecosta with the S9 I didn’t have the problem. The idea of ​​wearing the watch on the other arm also occurred to me today. I’ll try tomorrow.

[freeheeler]

@cosmecosta
I assume he meant that the same location in S9 as in A3P was not possible because of internal electronics etc.
