The watch shows too long drive distances (~ +10%) and eg. the distances to the green (front/middle/back) are wrong.
Was thinking if this was partly due to wrong map data as my son has an old Garmin Vivoactive where he needs to load the golf courses one by one, and Vivoactive gives much precise readings (checked with a laser meter). This is tested on many courses. I have used the "auto select" mode in Satellite. This should work fine in the middle of Europe as there should be enough satellites all the time availaible... What more can I do?
