Problem with GPS during open water swimming. When I use my Garmin swim 2 in Open Water, the distance that is recorded is largely inflated (like once it indicated 2 km while I swam 500m maximum). If I come back on the shore and just stand on the beach, the distance is still increasing even if I do not move. This happens with the 3 different modes. At the same time, the GPS of the running mode works perfectly on land.
