Coros Vertix 2 – turn off the dual-frequency mode on the GNSS Chip?
My initial testing with the Vertix 2 only used the all-constellation mode plus dual-frequency mode. Sorry! I got a bit carried away with the excitement of the new tech appearing on a sports watch for the first time (the dual-frequency).
However, I was pleasantly pleased with the results which, considering it was a new chip in a new watch, were good. Inevitably, sportswatch makers tune performance over the 6-24 months after release so the initial results bode well for further improvements.

How about using the recommended mode?
I toyed with using the recommended GNSS mode which has the dual-frequency disabled but thought better of it as my attention turned instead to the Samsung Galaxy Watch4 which was the first watch to run Wear OS 3. Too much tech excitement from another new product in the same month!
Then a reader (@Jason) contacted me and suggested that his results with the Vertix 2 showed that the recommended mode was better than the dual-frequency mode. My interest was piqued and, a few runs later, this is what I think…
Coros Vertix 2 – GNSS is one of the best
Regardless of the dual-frequency setting, the Coros Vertix 2 does have moments where it tracks slightly parallel to the correct track. However, that’s relatively rare and less rare when dual-frequency is disabled. It’s good most of the time when running, even when there are some constraints on satellite reception. However, like all watches, it does struggle when there are difficult urban reception conditions but still gives results that are ‘in the ballpark’ and which won’t make your post-run track look too crazy.
I’ve done quite a lot of testing now with the Vertix 2 and you can see 30 odd miles of testing here just on my standard test route – obviously, I use it elsewhere as well. You can click on this image (or this link) and look at the tracks on DCR’s Analyze software where you can zoom in or out on various sections and also compare against the Ambit 3 and V800 over the same route.
Note: These results are from different days and weather, satellite and other conditions ARE also different.

Mountains – Mount Whitney (the Rockies, USA. Source: Coros)
Note: Coros states this test has all frequency mode ENABLED on the wrist-worn Coros. The Garmin has GLONASS enabled and is mounted on a backpack for better reception.
This image also clicks through to DCR’s site to let you analyze two tracks from Coros when one of their employees recently ascended Mt Whitney. The Vertix 2 track is clearly better. Coros (the company) seem excited and proud with the performance they get in the mountains, especially as one of their target markets is mountaineers.
The ascent data in the source data files DO roughly match so I don’t think the files have been doctored in any way.
I’m getting some good tracks with this new chip folks!
