Designed to challenge even the most versatile athletes among us the Garmin Fenix 6 Pro handles just about any outdoor pursuit with preloaded profiles for tackling terrain on two feet swimming and surfing pedaling on or off-road golfing climbing...we could go on. Garmin keeps us plugged into the activities with valuable performance metrics specific to each sport like heart rate vertical gain flow on mountain bike trails and incoming metrics like weather forecasts and upcoming interval sessions. Plus the 6 Pro uses solar charging to pump smartwatch battery life up to 16 days GPS mode up to 40 hours and Expedition GPS Activity mode to a stellar 36 days. The 6 Pro monitors our body when not working out as well with an advanced energy rating system that lets us know if we are training too hard or not enough. It checks out things like heart rate breathing rate sleep quality and hydration to map out our current stress level so we can be informed about our performance potential. It even goes into VO2 scores for precision training expectations and predicting potential endurance race outcomes.
