Instinct 2 and Crossover Ultratrac accuracy.

I think you're really expecting too much from ultratrac. Ultratrac prioritizes battery life over the accuracy and it's more or less designed to give some amount of information and points.  The more you change directions within the pings, the more inaccurate it's going to be.  There's also some theoreticals it's made for like going on a rather straight path.

What do you want fixed on a feature that prioritizes battery life and gives little more than pings at long intervals just so one has some tracked points and directions?  The feature isn't broken and has its uses and it's not like Garmin is concealing how it works.

you're basically saying thar users should be happy for having a useless, annoyingly inaccurate feature, that records some random points, but at least saves battery life? oh thank God for that!

no, I think as a customer it's ok to have expectations to say the least.

by the way, I've read in the forums that they've fixed it. also found an in depth article where someone tested it on a long hike and the conclusion was that you should pause the activity when you're taking a break. otherwise the watch keeps collecting approximate locations and it draws a little spider web on your map, but when moving it was fairly accurate.

This reframing game of "so what you're saying is" and then you subsequently write what I didn't say, but what you want to emotionally charge so other people respond the way you want doesn't work.  I didn't say that.  I think you just need to understand how ultratrac works if you want to use it.  It prioritizes battery life.  The main thing is if you want better accuracy, you have to babysit it in the form of turning it off and on and/or adjusting the activity itself.  

I know for a fact people do hikes on Sweden's Kongsleden oder Hornstrandir in Iceland and they use Ultratrac for that.  If this doesn't work, you should try Coros and see what kind of a mess their version is.

That said, there was no reason for you to direct your hate at me about this since I'm not from Garmin.  I'm just telling you to understand how the functions work.  I'm also one that thinks Garmin should add adjustable intervals for pinging, like 30, 15, and 5 minutes.

ok it looks like you just wasn't aware that the feature was actually broken. so asking the OP "what do you want fixed...?" put a slightly different light on your comment, very much suggesting what I reflected on.

so it WAS broken until 11.18 I can confirm. It would add you dozens or hundreds of km's on a few km walk really. Now it is what it should be - poor brother of actual GPS accuracy. it will add you some extra distance here and there, mostly on turns or in town - but that is expected since there isn't GPS read every second. So yes, it is fixed and works, as much as it can

Which versions of the FW had broken ultratrac?  I've used it and didn't have that kind of deviation, so it must have been a version in between.

Cannot remember, pbly 8.63 onwards - there were threads on it for 8.6x and 9.2x versions

IMO 10.10 definitely has a broken version of Ultratrac - see https://forums.garmin.com/outdoor-recreation/outdoor-recreation/f/instinct-2-series/329926/incorrect-distance-when-using-navigate-or-track-me-with-ultratrac

Probably 9.23 too - see https://forums.garmin.com/outdoor-recreation/outdoor-recreation/f/instinct-2-series/310474/ultratrac-mode-wrong-distance-after-updated-to-9-23

Is there a page that describes how to get 11.18? Is it available in the UK? My Garmin Connect says 10.10 is the latest available.
