The Fenix 6 Pro has a lot going for it. With offline maps and professional analysis features it focuses on preparation and follow-up of outdoor activities. You don't need to be a professional athlete in order to benefit from this sport watch. However, you do need to know how to use it, which is not as simple as it sounds given the huge amount of features and lack of touchscreen.
