Another run in auto select mode. This is not cherry picking, both pictures from the same run where 80% of the track is off the sidewalks and lanes I have used. One bit shown in the picture is where I ran there and back on the same side walk so E3 can't even be consistent with itself...
I also hike a lot in the mointains and this margin of error is dangerous!!!
I am sorry to hear you are having this issue. For best GPS results we would recommend trying a few initial steps.
@MattBigmonster
Sorry but YOU are dangerous for rescue teams, if you quote the error margin of your GPS-watch to be dangerous for your hikes in the mountains! First you should learn to plan your hikes…
1 second.
I am more if a trail runner but I’ve seen similar on mountain trails. There is another similar thread started by someone else where I posted some trail comparisons with it diving off into bushes…
So add an alternative then with better GPS accuracy? I don't see the problem. Not that it's affecting the watch and it's durability..
Me myself don't care so much about it. Not often I need…
Exactly!
Instead of nitpicking about absolutely irrelevant stuff, most complainers here should actually try the watch in the outdoors 20km away from the closest house.
I'm sure Garmin didn't develop e.g. their Enduro 3 for people complaining that the entrance to their favorite soy latte macchiato place is 5m off the GPS location on the watch ... 
I replied to a similiar thread a day or two back and having has the Enduro 3 for two months and run it with an Epix 51mm and sometimes even a Coros watch, my feeling is:
With identical settings (auto / SatIQ) or both Garmins set to to ALL + Multiband the Epix is overall more accurate - far less wandering into rivers or buildings.
The Coros Pace 3 in All Systems but not multiband is pretty much the same accuracy as the Enduro in All Systems + multiband!
This drift into the river and then diving into the buildings after the bridge crossing is fairly typical (Enduro 3 is the purple line)
i do not think its terrible but it IS noticeably worse than the Epix 51mm for wandering off the actual track. I think Garmim simply traded some accuracy for battery life personally.
In my case its impossible to be a local mapping issue because I am running on bridges over rivers in my sample above, and all the watches are pretty much on the bridge (Enduro 3 slightly in the water)
I cant walk on water sadly, ergo the local maps are correct.
i think this is a red herring and be easily demonstrated as such if you are using more than one watch at the same time and one of the watches is on the expected location you ran or walk and the other is not which can easily be seen by paying attention to the purple track from the Enduro 3 here
