the watch is taking a warm bath

you have to treat nicely what you love

Hi again,
Sorry, but I’m still annoyed by this issue.
Both S9B and A3P on handle bar, recorded exactly the same ride: S9B recorded 539m elevation gain and A3P recorded 641m.
How could it be?

both calibrated at the begining of the activity?

@andré-faria Yes.

[Dimitrios Kanellopoulos]

@oktan link. Please so I can compare.

@oktan
I would bet on wind effect on S9B and lateral holes.

If confirmed by Dimitrios, try protecting holes with something like this

[Dimitrios Kanellopoulos]

@mff73 nah then the s9 would have had more. I suspect the opposite

@dimitrios-kanellopoulos
Oh yes, I misread it.

@mff73 We have people in Jerusalem with similar hats. I will borrow one

[Dimitrios Kanellopoulos]

@oktan the reason is because ambit 3 looks more jaggy in the data.

[sky-runner]

@dimitrios-kanellopoulos Ambit3 barometer has 1 meter resolution, Suunto 9 - 20 cm resolution if I remember correctly from looking at the FIT files - either that or Suunto 9 averages over 5 seconds which makes the altitude resolution look more fine grained. But that isn’t the reason Ambit3 has more elevation gain and Suunto 9 has less. These graphs don’t reflect elevation gain because if you simply add all changes on the graphs, that not what the watches report.

[Dimitrios Kanellopoulos]

@sky-runner yeah but adding all the changes even on QS that does not use those filters A3 has way more

@Oktan
I agree, I’ve been fighting since I bought it with support, from 2020. I joined this forum just to see if I’m the only one and if there is a solution. I have the 9 baro, I use it on a dinghy sail boat, they are always at unsuitable heights or -25m or +30. I’m thinking of selling it.
