I record GPS data with my Garmin smartwatch because X4 has no GPS receiver. I start tracking with my smartwatch in advance while I am preparing because the smartwatch needs some time to set the GPS position correctly. When I am ready to start my hike I start recording on the camera with the app whereby the camera’s time is synchronized accurately. At home I embed the GPS positions in the photos with exiftool. Then everything is perfect.
But I really want to improve the precision of my GPS tracks and so I thanks all writers here for their valuable inputs.
Feels odd that my aint better maybe I need to test this with a weight as @brunofilmklov does Orientation stabilization… Bruno where did you buy your weight?
