Marathonian and demanding hiker, I chose the Fenix ​​7 Pro for its high precision GPS and its legendary autonomy. Used daily for 3 months (running training, alpine trails and mountain navigation).

See the Fenix ​​7 Pro and opinions on Amazon

First contact and installation

• Perceived quality : Reinforced polymer housing and anti-scratch sapphire glass. Robust design (military standards MIL-STD-810) but heavy (82 g)

• Handling : Configuration via Garmin Connect Intuitive, but 2-3 days delay to master the touch/physical buttons.

Real test vs promises

• GPS : Surgical precision in multi-frequencies (maximum deviation 5 m in canyon vs 30 m on Forerunner 245). Satellite locking.

• Battery : 22 days in watch mode (confirmed), 6 p.m. in multi-band GPS + music. Unusual solarization under cloud climate.

• Key features ::

  • Integrated LED lamp (night security).

  • Endurance and elevation performance score (implacable analysis of weaknesses).

  • Preloaded topo cards + route deviation alerts in real time.

Disappointment ::

• Sometimes illegible MIP screen without backlight (shaded forest).

• Improved heart sensor but less reactive than a chest belt over short intervals.

• Prohibitive price (€ 899) for underused functions (surfing, water skiing).

Key points for the buyer

• For whom : Outdoor sport (trail, mountaineering, triathlon) requiring extreme reliability.

• For whom not : Occasional or urban runners (Forerunner 265 sufficient).

• Alternative : Apple Watch Ultra 2 (better interface, less autonomy) or Garmin Enduro 2 (XXL battery).

Cash verdictStrengths ::

1. Unparalleled autonomy in a hostile environment.

2. Most precise GPS on the market (multi-band + Glonass/Galileo).

3. Undeamnated sustainability (shocks, temperatures -20 ° C at 60 ° C).

Weak points ::

1. Less reactive screen than the Epix Amoled.

2. Justifiable prices only for ultra-enduring.

3. Poorly useful solarization in northern Europe.

Recommended If you accumulate> 3 p.m./week of demanding outdoor activities. Sustainable investment (5 years+), but oversized for leisure use.

Comparison: Garmin Fenix ​​7 PRO VS 4 Other Watches

Advantages acclaimed by the Garmin Fenix ​​7 Pro

1. Exceptional GPS precision

   • Multi-frequency technology (GPS, Glonass, Galileo) with satellite locking.

   • Results almost identical to dedicated GPS such as the GPSMAP 66SR in hiking.

2. Record autonomy adapted to expeditions

   • Up to 22 days in watch mode and 40 hours in multi-band GPS.

   • Consumption measured at 28% for 73 km in 10:46 a.m.

   • Shipping mode extending autonomy to 40 days (74 days with solar).

3. Integrated high -end cartography

   • Preloaded topo cards with real -time diversion alerts.

   • Climbprro function to anticipate elevation gain + screen display (stats/card).

   • Creation of roads directly on the watch.

4. Military sustainability and waterproofing

   • MIL-STD-810 case resistant, temperatures (-20 ° C at 60 ° C) and immersion up to 100m.

   • Anti-scratch sapphire glass tested over 3 years in extreme conditions (mountain biking, mountaineering).

5. Pushed training analyzes

   • Hill score And Endurance score To quantify the progress in elevation.

   • Training Readiness : Daily evaluation of the ability to train based on sleep and recovery.

   • Multi-LED cardiac sensor (+15% precision vs fenix 7 standard).

Appreciated bonus ::

• Integrated LED lamp to secure night outings.

• "Resume Later" mode to suspend an activity without emptying the battery.

• Compatibility with Spotify and Garmin Pay for daily use.

Notable limits ::

• MIP screen less reactive than amoled (reduced visibility in the shaded forest).

• Low -effective solar recharge under cloudy climate.

• High price justifiable only for intensive outdoor athletes.

User verdict : A pro tool for endurance and adventurers athletes, combining extreme reliability and sharp technical data. Overlapping by the Ultra 2 Apple Watch in urban areas.
