Two images of the 66sr and the 67 where we see that the management of the Galileo satellites is totally different.

Let's revisit this subject after the next firmware update

Ooh, the suspense is killing me

Just for fun, I took some screen captures from several devices after they all collected satellite data for about 30 minutes:

I will refer to the picture from the Gpsmap 66s device, in my opinion the satellite signal has disappeared,
the signal from three satellites does not give a basis for determining the position,
and even more so for determining the height above sea level.

Early on, the signal had to be of higher quality.

That is what our 66s displayed after being in direct sky view for more than 30 minutes.

OK. That was just my observation.

I also want to point out that the devices show a different value of GPS or GNNS indications 8 ft, 17 ft and 6 ft in the case of Gpsmap 66sr and Gpsmap 67 devices, the signal indicator bars are different.

The coordinates show that all devices point to a point the same distance away from where it was located
devices, i.e. Gpsmap 66sr and gpsmap 67 do not indicate a more accurate position than devices that show a higher
gps indicator and their pointers show weaker satellite signal.

The GPSMAP 67 is also tracking one additional GNSS Constellation compared to the GPSMAP 66sr.

The displayed coordinates have been edited for privacy purposes, and should not be considered for this exercise.

I believe the original post author was more concerned about the 66sr displaying more Galileo satellites than the 67. The images shared show a different result for these two devices, and provide additional reference comapred to multiple other devices.

I was convinced that it was unlikely that four devices would point to exactly the same position,
but I didn't want to question it so directly.

... and it hundreds of miles east of Hawaii in the Pacific Ocean. The original posts accuracy was close enough you see the solar panels on his roof. Probably a good reason to hide/edit your location in posts if it's your residence.
