The fenix 8 Pro multisport GPS smartwatch is a breakthrough for serious runners, climbers, watersport athletes and others challenged to stay in contact where it’s impractical to carry a phone. This is the first Garmin smartwatch with built-in inReach technology1 for satellite and LTE connectivity. Leave your phone behind during an activity, and access voice calls and LiveTrack location sharing when you’re connected to an LTE network. Or utilize two-way messaging and interactive SOS messaging capability during an outdoor adventure from either an LTE or satellite link — all powered by up to 15 days of battery life in smartwatch mode.
New Features as of November, 2025
NEW! HEALTH STATUS
See whether your health metrics — such as resting heart rate, HRV and Pulse Ox2 while sleeping — are trending away from your usual range, which could indicate added stress to your body. These changes could be related to physical activity levels, environment, stress, alcohol intake, potential illness, and more.
NEW! ENHANCED NOTIFICATION CONTROL
NEW! RALLY 110/210 COMPATIBILITY
New Features on the fenix 8 Pro 47mm vs. fenix 8 47mm
NEW! SOS AND GARMIN RESPONSE
In an emergency, inReach® satellite technology allows you to trigger an interactive SOS message to the 24/7-staffed Garmin Response coordination center1.
NEW! SATELLITE MESSAGING
When you’re venturing into off-grid locations, including up to 50 miles offshore, the watch’s inReach technology allows you to send messages and get location check- ins — once you establish a satellite link — with no phone connection required1.
NEW! LTE CONNECTIVITY
Going for a run? Taking a swim? Leave your phone behind, and use your watch’s LTE connection to exchange messages and make voice calls — plus let friends follow along with LiveTrack™ location sharing and location check-ins. Even get access to weather conditions and forecasts.
NEW! PHONE-FREE VOICE CALLS
When you have an LTE connection, the Messenger Calls app on your watch lets you initiate and receive voice calls with other Garmin Messenger™ app users — without carrying your smartphone along1.
NEW! MESSAGING ON THE GO
Through satellite or LTE connection, messages can be shared with other Garmin Messenger app users directly from your watch. fēnix 8 Pro will automatically sync with the Messenger app contacts when your watch is paired with your smartphone1.
NEW! NO NEED TO SWITCH PROVIDERS
You’ll activate your subscription through Garmin, not your cellular provider, so access to inReach® services is a seamless connection through your watch1.
NEW! SAVE POWER WITH LTE-M
fēnix 8 Pro connects to the LTE-M network, which is designed to use less power than standard LTE communications — minimizing battery drain on your watch to keep your adventures going longer and stronger1.
NEW! LIVETRACK™ LOCATION SHARING
LTE network connectivity lets friends follow your adventures with LiveTrack location sharing. Alert your friends that you have started a LiveTrack session, in case they want to follow or reach you during your activity1.
NEW! WEATHER FORECASTS
Access to current weather conditions and multiday forecasts are available via LTE to help you stay prepared for what’s ahead on your route1.
NEW! LOCATION CHECK-INS
Over satellite or LTE, user-initiated location updates can be sent to family and friends, keeping them apprised of your progress on trips and adventures1.
NEW! RUNNING ECONOMY
Measure your overall energy efficiency while running — using long-term running volume, stride length and step speed loss — when you pair your watch with the HRM 600 monitor (sold separately).
NEW! RUNNING TOLERANCE
Better understand the impact each run has on your body, and get a recommended weekly maximum mileage so you can keep training effectively without taking on too much.
NEW! STEP SPEED LOSS
Improve your running form, and understand how much you slow down when your foot hits the ground when you pair your watch with the HRM 600 monitor (sold separately).
NEW! PROJECTED RACE TIME
This race-time prediction is what your race time and pace could be if you keep training well all the way through to the race date entered.
NEW! SUGGESTED FINISH LINE
If you have a course loaded for your race, your watch can suggest trimming your data to the finish line if you forget to stop your timer.
NEW! AUTO LAP® BY TIMING GATES
Your watch will recognize when you cross mile or kilometer course points and trigger auto laps there versus GPS-based miles or kilometers when following a course.
NEW! GARMIN COACH ADAPTIVE TRAINING PLANS
Train for an event, achieve a milestone, or improve your fitness with Garmin Coach training plans for running, triathlon, cycling or strength. Select plans adapt daily for personalized workouts based on your performance, recovery and health metrics.
NEW! TRIATHLON AND MULTISPORT PROFILES
Automatically record splits with built-in profiles for triathlons and swim/runs, or you can create your own.
NEW! EVENING REPORT
Prepare for tomorrow before bed with a reminder of sleep need, tomorrow’s workout, weather and events.
NEW! SMART WAKE ALARM
The smart wake alarm gently vibrates to wake you at the optimal time.
Plus, all the great features of the fenix 8 series
