It’s easy to geek out over Garmin’s Fenix 6 Pro Solar. Recording activities is just a part of what this gadget can do. Monitoring heart rate and oxygen, it sheds light on stress levels, body battery, and sleep patterns. I feel like I have a better idea on how to recharge each day. The Fenix 6 takes time to get used to, and there are several features I haven’t used yet, such as music and pace-setting. Oh yeah, it also tells time. Available at Uphill Pursuits; $800.
