Hi, I have the watch since a few days. At third hike it made that errors like shown, completely falsing the result. It was a forest area w/o any infrastructure like electric lines or radio masts, clear sky, and the biggest errors happened at about the top of a hill, in not very tight forest with big trees. At the first big negative peak, I didn't touched the watch, at the big positive peak, I have shortly switched to compass. What could be the reason, is it normal? At 2 first walks (also in forests) it was all OK, no such errors. (vertical meters)
