i continue having problems with the altimeter items

Carles Merin

hello, i have a suunto 9, with the last version of software, and yesterday night, i sincronise with pc to put a route inside.
today i made this rute with a friends, 3 with suunto , 9 baro, and 2 ambit sport, and 2 fenix 5… we run the same rute, and all the watches have a similar meters of altitud acumulated, but my watch have and exagered number of meters climbed. the other watches, garmins and suuntos, have a normal diference of 10 or 20 meters of the 700m total, but my suunto have 870m climbed, 120 meters more than the others.
the gps was sincronise, i have selected gps + glonass, but always, every day i have problems with the meters climbed.
anyone have idea that what is the problem? im very bored of this , and i m thinking about sell this suunto and take a garmin 5…always i have problems.
thanks for your answers

@Carles-Merin
it could be a faulty baro component (dirty or faulty).
If dirty, a quick search here will show you some test to do check , and clean
If faulty, your best friends now is suunto support which it likely to change your watch : it could arrive.

you can try to check if the venting holes for the pressure sensor are always clear and not blocked from wet skin… I’ve had this issue with a Suunto Core once.
But it gave me a 5 times wrong result.
I assume this can also happen with the S9 as the sensors holes are located at 9 o’clock and you want the OHR sensors to work properly and hence tighten the watch straps a bit more… right?

gracias @Mff73 , its the version without baro, only suunto 9… i send mails to the suunto support, but they dont help me with a solution…the other suunto i had, spartan, i had problems too, and i send to finlandia, and the gps rreturns with the same fail…i dont know what i have to do

@Carles-Merin
alright, forget about my post…
GPS altitude is always less precise than with baro.

Carles Merin

yes, correct, but my friends have ambit 3, and the precision was perfect…i dont know how explain this

freeheeler

@Carles-Merin
Ambit 3 what? Run? Sport? Peak?
EDIT: …sorry, you mentioned it…
maybe it’s because of a different GPS chipset… but there are people here knowing that better than me!
I thought I give my input on that question that was related to pressure sensor is measuring “pumping on skin”…

Carles Merin

@TELE-HO its the version without baro, thanks

Carles Merin

@TELE-HO one ambit sport, and 2 ambit run,

Try to reset GPS - see https://www.suunto.com/Support/Product-support/suunto_ambit2_s/suunto_ambit2_s/adjusting-settings/service-menu/ (this should be the same for A3 too).

it a suunto 9. i made a factory reset a few months ago with moveslink

@Carles-Merin The Garmin5 series have barometers. Without a barometer the GPS altitude is just not that accurate. On larger climbs it seems to do better but not on small ones. The S9 without a barometer will not record an altitude change unless it is over 7m. If the altitude is important to you, the S9 with a barometer is a much better choice.

Carles Merin

ok thanks. i know this, with barometer is more exact, but other suuntos like ambit run and ambit sport 3, give the correct values, and my suunto, that is more actual, give an incorrect values of altimeter

Brad_Olwin

@Carles-Merin Make sure the AGPS file is current so always sync the watch with SA before you go. I do think there is room for improvement with the altitude in GPS. The antenna on the Ambits is outside the watch and the chipsets are different but you should not be that far off. Have you used Dimitrios’ QS site to see where the differences are? In addition, do you have the latest firmware?

Carles Merin

@Brad_Olwin yes i have the last firmware, and i sincronise the watch until go to run, but the values dont be correct.i find satelits, and i wait 2 o 3 minutes to have a better signal, but dont works well…sometimes, i start the move, and i m running downhill, and the suunto is increasing the meters of climb up!!! how can be this ??
i really very bored with this watch…it have a good estetique, but the software give me a lot of problems…

@Carles-Merin ill create an issue for this.

Carles Merin

@Dimitrios-Kanellopoulos thanks.
