Been using my Garmin Forerunner 255 for a year now mostly for skate skiing and running. I got it for the gps/map accuracy and it’s been wonderful until now. My last two skate skis the maps have been wildly off as in each lap I do looks like it’s in a different place. Pictured is a ski I did earlier this week where the map is spot on and a ski I did today. Both at the same place and about the same distance. I haven’t changed any watch settings and I have it set to the most accurate satellite systems. Also make sure it’s locked onto GPS and green for awhile before starting my activities. Any thoughts?
