Whatever plateau we're breaking through, Garmin's fenix 8 AMOLED Sapphire Sport Watch is tracking and driving our every step. The bomber, submersible construction meets the moxie required for rugged terrain and technical pursuits, while the heart rate, ECG, and blood oxygen saturation metrics clue us in to how our body is handling the demands. With 145 hours of juice in max battery GPS mode, this watch outlasts the sun time and time again, while the built-in LED flashlight comes to save the day when our headlamp flickers out. However deep into the backcountry we go, the SatIQ tech keeps our position locked in without draining the battery.
