TOUCHSCREEN AND BUTTONS
Traditional button controls that work in any environment are matched with a responsive new touchscreen interface for quick access to selections and functions.
BUILT FOR EXTREMES
The rugged, sophisticated and lightweight design features a large 1.4” solar charged display and 51 mm case with sapphire lens. The UltraFit band provides long distance comfort – even in punishing conditions.
This activity profil eallows you to see heart rate, elevation, segment times and other metrics when the race is on. It records GPS in this mode but is unavailable for viewing, in keeping with adventure race rules. A summary screen even helps verify your finish time with the race committee.
To help guide your way in low-light conditions, a built-in superbright multi-LED flashlight (twice as bright as the fēnix®7X multisport GPS watch) provides quick access to a bright, steady beam in either red or white light.
Optical heart rate technology4gauges activity intensity as well as heart rate variability to calculate your stress level. It also tracks underwater without a heart rate strap.
