GPS Accuracy? Multiband?

Agreed. There’s been no GPS improvements since the FR305 I first had . But the F7 looks nice so who cares?

I very much like Multiband GPS, as I find it far more accurate in practice. It's also much more responsive to small positional changes. I find where it excels is in curvy areas, such as a running track. Also, if you're running around tall trees, the multiband has less drift compared to single band.

I recorded quite a lot of tracks with multiband activated and without. I don't see much difference. "GPS only" vs "All satellites" does make a difference.

Yea "all satellites" is way better than my Fenix 6 accuracy. It's even a tad better than my 935 which is spot on most of the time.  

my old Fenix Chronos used to record 420m of climbing for my regular bike route. the Fenix 7X showed me 460m on the same route. now with software 7.35 it is back to 420m. My phone records 460m. So, Fenix 7 GPS is as good as to say it was over 400 meters.. ;)

I always thought the GPS was fine in my VA3 and Fenix 6X, the accuracy was always within expected tolerances (+/- 10 meters or so) so my tracks were a good representation of where I went, and distance measurements were always good.

But the F7 accuracy with all-systems + multiband is on a whole other level. Distances aren't any different in my experience, since it was always fine before too, but the track accuracy is noticably better. Like, +/- 1 meter, or maybe 2 meters at worst.

So in summary, it was perfectly acceptable to me before, and I never complained, but it is undoubtedly even better now on the F7. Also, signal acquisition time is vastly better now as well. I'll get a lock in 5 seconds, where it used to take 20-30 seconds.

I would totally agree.

I am a rally codriver and was using a Fenix5 for recording the special stages, and in these "extreme" conditions it was struggling quite a lot to record the track. When I heard about the almighty multiband with 5x the accuracy I bought the Fenix7SS. I can say a REALLY BIIIG improvement is the GPS lock time, previously it took from 30sek to 4 minutes to acquire the GPS in the forest when we started the special stage, now it takes 5 to 10 seconds, huge bonus..... BUT, the rest it is basically the same, maybe I would say 10 to 20% improvement, nothing more... It is a small, just a small improvement, sure not as big as the marketing numbers....

Most GPS devices will struggle with the car roof blocking the line-of-sight signal from the satellites. If you haven't already tried this, I would suggest switching the watch to the wrist that is closer to the side window, as that might reduce satellite signal blockage and improve accuracy.

Thanks for all the feedback, everybody.

Multi-band has definitely improved distance accuracy for me.

Here is just one example from a trail run on Rattlesnake Mountain (Seattle, USA) that I did recently with 6X and later with 7X (with multi-band enabled).

The official distance shown on trail markers and on the map is 10.2 miles one way, 20.4 miles out and back.

6X - 19.36 miles, 5% short.

7X - 20.04 miles, 1.5% short.

Also, here are the distances for the above activities after I had done distance correction in Strava:

6X - 20.20 miles, 1% short.

7X - 20.24 miles, 0.8% short.

So clearly, 7X is quite closer to the official distance, and the difference between the distances before and after the correction is also much smaller than in 6X, however even in 7X that can still be up to 2% if a trail is particularly wavy. But in 6X that usually was 5% or greater.
