@mrony how high are the deviations and how is the refernce defined?

10meters is also ok. 20 no. only as an exception

If you want me to analyse what happend please provide a link from suunto app, the expected values and so on

freeheeler

@dimitrios-kanellopoulos
that’s what I understood, yes.
and no adjustment of the altitude prior to the activity

@mrony Does that picture illustrate how you were wearing the watch? If so, it looks like the barometer holes covered by your shirt…

@fazel
I also check that my sleeve goes below the watch.
But let’s see his QS graph first, once he shares it… or the link to Dimitrios

@freeheeler said in GPS altitude meter:

personally I would only worry about the 90m low.

Yeah, I mean, come on, 11m on 2347 peak? That is less than 0,5%…
It’s like going 100 km/h with your car but your speedometer is showing 99,53 km/h…

I decided to buy S9B instead of Polar or Garmin after reading DC Rainmaker review in which he said that S9B was the only one on Stelvio showing altitude different only 0,5m than real. And since altitude was crucial for me, S9B it was. But I was not expecting S9B to be 0,5m accurate all the time.
Am I disappointed? Absolutely no! Most of the times accuracy is about 99,7%, quite often reaching 99,9-100%, worst I have seen is no lower than 99%. I think it is great.

@kabzior
that’s what I’m saying further up.
90m is a bit mutch but everything below 20m easy for me

stelvio? I envy you

@freeheeler hello, sorry for the late response, tomorrow I’ll be doing another tour to a registered peak! as soon as I have these values, I share them! I still have the clock (according to customer service) set to factory settings! BG

MRony

@freeheeler Hello, I was on a tour today and the values were right (reset the clock to the factory settings), there was a deviation of 10m on the first summit, 1m on the second and 5m on the third !! Thank you for your support! Best regards, Rony
