Suunto9 Baro Elevation Issues
-
@Oisinb
Either the wind, or your hand is blocking the holes while moving your wrist. -
I’ve just come in from a run…exactly same as yesterday…Baro 9 recorded exactly same distance BUT a 25 metre discrepancy between the 2 runs over 4 mile??
I’m having major doubts about this watch as never had a single issue with my Fenix 5x
I really want to work with this watch but I’m quickly losing faith after 1 week??

If you think this can only get worse, I would return it.

@Oisinb I once had a hike up a hill in very high wind that almost blew me off of the mountain.
Elevation data for this activity was bad as well - while usually there are absolutely no issues at all with the S9B.
Others are right - the barometer holes are facing forward when the watch is worn on the right hand.
It then depends on clothing and running style if there is an impact in the altitude measurement.t6, S6, Elementum Terra, Ambit 3 Sapphire, Spartan Ultra Copper, Traverse Alpha, S7 Graphite LE, S9B Ambassador, S9P Granite Blue Titanium, S9PP Titanium Sand, Vertical All Black, Race Titanium Charcoal, Race S All Black, Race S Titanium Canary

25m in distance or altitude?
If distance: this is a very good accuracy over 4miles, but off topic in this thread
If altitude: what is the absolute altitude gain/loss during those 4 miles? -
@Egika sorry it was an altitude difference of 25 metres over the 4 miles

@Egika
my favourite topic
blocked holes is the reason in most cases IMHO…
strong winds could also be a reason as wind equalizes pressure differences and hence the baro gets “tricked”. but should be compensate with fusedalti…?! -
@TELE-HO yeah - it’s not compensated. Fused Alti is relevant for the low pass filter offset over all - while the baro sensor is responsible for the quick changes (and thus influenced by heavy wind and other stuff like getting some air pump effect from moving clothes worn over the watch )

I have a very similar issue. I have just purchased a 9 Baro and went for a 54 I’m ride which was a flat route around the Bay and along the beaches of Singapore. The GPS tracked the route perfectly but the altitude measuring recorded 6.3km of ascent! I think the highest point of the route would have been about 15m near home away from the coast. The plot shows wild variations with a Low point of -116m as per the attached plot. I never had such issues with my Ambit3P and this should be a superior product. Any suggestions, or is this one to take to Suunto support?

@Cookiemonster It only happened once to me (well, except kayaking, that’s a different topic though) wearing the watch inside the jacket during a very strong storm, with very strong winds. I guess you didn’t wear long sleeves in Singapore right? I never did
Maybe your arms were bent enough to create some kind of vacuum around the baro sensor?
