Calibrate altimeter

Dear forum colleagues, how do you calibrate the altimeter? I've not been able to see how to do this. The values shown are not the right ones, so calibration is needed...

Best regards-

    Agree. A £200 device with HR Strap is not a cheap item. If it has an elevation function or should be reasonably accurate with a way to calibrate it. Anyone from Garmin read these posts that would care to comment on a fix as there is potentail brand reputation damage and customer confidence issues where functionality simply doesn’t work. Reference new device at sea level in Peterborough was reporting out of box at -20 which was ok. Updated firmware to V3 and had a starting evelation on Manchester 100mile in Wythenshawe as -80. None of Manchester or Cheshire is below sea level. Come on Garmin sort it out please.
  • Yep, I agree.

    On my commutes to work the altitude is out by more than 100 m: I'm always riding below sea level.

    Having accurate current altitude is important to me, especially on longer rides with climbs as I know the height of the 'col' on a climb and would like the Edge 130 to give me an indication of how much more climbing is left to reach the 'col'.

    For a £200 device - I paid for the Edge 130 with HRM strap - the performance of the Edge 130 is very poor.


    The major problem is, they do not allow to calibrate. If you understand how automatic evelevation calibrations works together with GPS, you will realize as quicker you start, as more inaccurate it is. I don't care about elevation that much as long as total ascent/descent seem to be fairly accurat - which it seems to be.

    Yes, this is my experience too. Was fine until the latest firmware since when i've been below sea level by up to 60m in London. As above, absolute height is important - how much more climb have i got to the top of the mountain?

    What's absurd is my older Garmin Edges (200/Touring) which did NOT have barometric so were relying just on satellites gave 'accurate enough' altitude readings. Adding the barometer but without any way to calibrate makes it useless. If Garmin won't add calibration then they need to disable the barometer.

    Customer Service suggestion was a hard reset (which suggests perhaps there is some auto calibration on first boot?) but setting up display preferneces and linking devices takes about 15 minutes - that can't be a long term solution as it would be a regular as weather systems roll through

    Same problem. I bought the edge 130 since May and it's getting worse. Especially from 3.0 firmware.

    I lost 80 meters from my real altitude. I work 10 meters from the beach and altitude is - 80 meters.
    One day to another there is no reason for "random" altitude (same pressure, same GPS fonction, same firmware).
    I bought it especially for the altimeter for mountain bike.

    Very disapointed from this device and the way Garmin (does not) fixe that bug with no listen their customers.
    Because it's an enormous bug whatever they say.

    Altimeter calibration seems to be getting worse. Commutes to and from work yesterday and today have been recording elevations more then 200 m under sea level.

    Would be good to hear from Garmin the reason why recorded elevations are wildly inaccurate - as I've reported previously such inaccuracies on a £200 device is woeful - and whether this will be fixed in forthcoming firmware releases, with some idea of timeline.

    I too. With FW. 3.0 altitude -115 mts and light not shines when cycling too.I made hard reset but not solution.

    Yes, my altitude recording has got much worse this week. I had a few days last week where the readings were pretty accurate but this week my commute has been 500 feet below sea level apparently. I have a fairly consistent commuting routine so nothing has changed from my perspective. I really am getting fed up with this Garmin.
  • The absolute altitude calculated by Edge 130 is wrong. I'm not sure since when, if it has something to do with firmware 3.0, or just the air pressure is changing more in the autumm, but it drifted more and more in both directions. Last week I've got for the same place the altitudes -30 and 180m (correct is 100m). The altitude gain and loss are OK, so the problem is the calibration.
    My 8years old, 25€ SIGMA BC14.12 has the possibility manually calibrate the altitude, I'm wondering why the Edge 130 doesn't have this feature.
  • come on Garmin and fix this !!!!!
  • I have the same problem. Latest software installed but absolute elevation goes to -130m and before was 77... I really hope that Garmin will release some quick fix for this.
