GARMIN: Which GPS combination works best for you?

[xsquared]

Do you notice a significant difference between using GPS only, GPS+Glonass and GPS+Galileo?

I've had it set on GPS+Glonass to start with but one day all my activities' routes were moved about half a km from where they should have been, so I switched to GPS+ Galileo. It's been fine except maybe it's taken a bit longer to connect to GPS.

Reading various websites, they all seem to say a combination of GPS + something else would make it more accurate, but have you noticed if you've tried them all?

I'm on +Galileo at the moment, +Glonass was taking an age to connect in September so I swapped.

I don't really see any difference in accuracy tbh. I have regularly run the same routes for years and GPS might vary 0.1 miles at most over a 10 mile run (and that's on all GPS types on the three different Garmin watches I've had).

If I'm out near the coast or in an area with lots of high buildings it can mess with GPS. I've found discrepancies are usually related to the environment rather than settings on the watch.

Thanks for yout insights poopy.
