Garmin Fenix 8 Review Summary – The Quantified Scientist Weighs in

The Garmin Fenix 8, a flagship outdoor adventure smartwatch, has garnered attention for its robust build and extensive features. However, findings from The Quantified Scientist reveal a mixed performance across its functionalities, raising questions about its value for money. Here is a summary of what he had to say

GPS Tracking: A Standout Feature

In GPS tracking, the Fenix 8 showcases “reliable performance with consistent results over multiple trials,” according to The Quantified Scientist. Its accuracy and dependability make it a strong contender for outdoor enthusiasts and navigation-focused users.

Sleep Tracking: Room for Improvement

While the Fenix 8 performs relatively well in tracking deep sleep, it struggles with detecting REM sleep. The Quantified Scientist noted that REM detection inaccuracies remain a significant drawback, though Garmin’s newer algorithms may offer slight improvements compared to earlier models.

Heart Rate Monitoring: Mixed Results

Heart rate tracking on the Fenix 8 demonstrates minor delays, particularly during rapid heart rate changes in dynamic exercises. The device fares better indoors but faces challenges during weightlifting due to arm tension, a limitation highlighted in tests conducted by The Quantified Scientist.

Price and Alternatives

With a price tag of approximately $1,200 for the Solar Sapphire version, the Fenix 8 stands at the premium end of the market. The Quantified Scientist points out that alternatives, such as Garmin’s own Enduro 3 and Epix 2 Pro, offer similar functionality at lower prices. Non-Garmin options like the Coros Vertix series and Amazfit T-Rex 3 provide competitive features for a fraction of the cost.

Final Verdict from the Quantified Scientist

While the Garmin Fenix 8 excels in GPS accuracy, battery longevity, and sensor integration, its heart rate and sleep monitoring capabilities lag behind competitors like Apple and Fitbit. The hefty price tag may be difficult to justify for users who prioritise these features.
