Elevation Gain Problems
Hello,
I'm a long time Karoo (2) user but first time posting.
For the past 9-12 months or so, my elevation gain ride data is wildly incorrect - massively over /higher what it should be. I know this was a topic a few years ago, but I don't see anyone talking about it now.
I've tried resetting the device, setting up my profiles and sensors multiple times and when I do that it seems to be fine for a few rides, then reverts back to being incorrect.
Is anyone else still having this issue or is it just me? Any advice would be greatly appreciated,

Unfortunately there is nothing you can do. Even the replacement unit I received was inaccurate. And if you try to exchange it, HH will tell you there is no guarantee that the replacement unit will work any better. They have known about this issue for years and still didn’t update their hardware. They refuse to add any smoothing or allow us to use map data as a replacement. Your only option is to return it or deal with it. And I have a feeling that K3 will have the exact same problem as people reported K1 having elevation issues as well. They have also promised that they would look into this and try to correct it software side but they never did and don’t admit there is a problem. They say some units are affected yet unable to track down the reason, lot, source of the issue. I hope Ali reads this and can update us again on this topic.

this has been discussed endlessly both here and on the Facebook group....my findings were when using 2 Karoo units, one on my handlebars and one in my pocket was that the one on my bars [and I did many tests swapping the units around] was always giving me 20-25% more elevation gain than the one in my back pocket...obviously the vibrations on the bars affect the barometric altimeter...there is and will never be a fix.
try and do the same ride with the unit in your pocket and see....

It is a long running annoyance discussed here and elsewhere. Over the past weekend my K2 starting point automatic calibration was 700ft higher than the official height at that spot and even after manually entering the correct height the unit still recorded 4300ft extra ascent after my ride.
I'm done. Despite its faults and niggles I'm switching back to Garmin, at least they have a more reliable and consistent platform for recording data. -
I'm experiencing the same issue: my elevation readings are consistently twice as high as those of my friends and even my Apple Watch. Despite diligently checking for updates and reviewing logs, no fix seems to have been implemented. I'm considering abandoning the Karoo and relying solely on my watch for tracking.
"..obviously the vibrations on the bars affect the barometric altimeter...there is and will never be a fix." => If Karoo were to compare tracked data with route data when a route is set, it could potentially rectify the elevation discrepancy more accurately than relying solely on recorded data.

yes, I find this issue crucial, especially for those who engage in somewhat competitive riding. I've been advising people against purchasing Karoo at the moment due to this problem. Even if a software fix isn't perfect, it could make a significant difference. Providing an option to smooth the elevation data would be greatly appreciated.
In my latest ride, my Karoo showed an elevation gain of over 1300m, while my friends' devices (Garmin, Wahoo, Apple Watch) indicated only 500-600m. They keep teasing me about my Karoo, and it's messing up my Strava stats big time. -
Seems like still an issue. I'm about to ship back by second Karoo2. First one was showing wildly overstated elevation gains. 1700ft higher than my companions and when corrected in Strava (over 100mi). Second one showing understated elevation gains - 1300ft lower over 60mi. Really hope this 3rd replacement unit fixes things.
You can see something really weird happened in the middle of a continuous climb with a sudden jump in elevation. Weather wasn't great and flip-flopping between fog/drizzle/sun but never had this issue with my Wahoo and kinda wish I had stayed with it at this point. Now will be out of a head unit for another 2 weeks...

My Karoo usually reports an ascent/descent that is at least 3 times to high on more or less flat roads. It gets "better" if more real hills are added, then it reports only 25% to 50% to much. Really ridiculous that this is not sorted out for years!
This is a recent recording of what should be a completely flat road. The altimeter wildly changed every few seconds for a meter up and down, thus adding a huge amount of ascent/descent where non is. This should be quite easy to fix with a filter in the software.

I also have elevation discrepancy of a small margine, but it's always there, and its in minus for about 20-30 meters of elevation when rising for about 1000 meters. I live on 300m above sea level, and if I climb for about 700m (1000m above sea level), the Karoo 2 shows 970 meters. And elevation gain seems to be spot on.
-
Franco, your numbers are pretty moderate compared to mine, my numbers around Berlin are often so far off that Strava simply ignores the GPS and does the elevation correction automatically. My record is over 13 km(!) of elevation gain mostly along the canals from Oranienburg to Eberswalde...
(The same unit works just fine in Finland so don’t say it’s a hardware issue. Use of mobile data and where you ride seem to be the biggest factors, but of course there can also be different bugs triggered by different conditions.)
-
@Anna Ronkainen, I don't use mobile data, and here in Slovenia I just have a slight elevation discrepancy, but it is there.
I am talking about 30meters per 1000 meters of elevation. So it is about the device it self as well.
But how come some of you have so much of a difference, like riding a bike in Himalayas (if there would be roads)!? Thats outrageous, it really is.
