Hi. I have this watch for a week and this is my fourth run with it. So far the GPS accuracy was great, however today the whole path was offset with about 150m to north-east. The recorded path is also quite wide.I ran along the south side of the road marked in green the whole time, so the red lines should be pretty much on top of each other.
The watch is FR245 non music. Software is 5.50. Using GPS + GLONASS. Do I need to calibrate it or something? The sky was pretti clear and there are no tall buildnings around.
PS. Here is previous run with the correct GPS patch for comparison:
