GPS Accuracy

GPS Accuracy After a recent walk, I decided to analyse the data from the Garmin FIT files - one from my eTrex 25 and the other from my Apple Watch 4 and iPhone XR. I was purely interested in seeing how well the Garmin eTrex 25 was able to act as a tracker - mainly as when I was using it for my geocaching walk, it seemed to be tracking me, but looked on the screen to be sticking purely to the paths in the grounds of Wollaton Hall, which was a bit surprising.
