The Quantified Scientist - Garmin Fenix 8: In-Depth Scientific Review
The Garmin Fenix 8 is designed for outdoor enthusiasts, offering a large screen, long battery life, and solar charging options. It excels in GPS tracking, making it ideal for adventure activities. However, its heart rate tracking performance is inconsistent, particularly during cycling and weightlifting, where it struggles with rapid heart rate changes and tension on the wrist. The watch is compared to other Garmin models like the Enduro 3 and Epix 2 Pro, which offer similar features at lower prices. The Fenix 8's sleep tracking is decent, especially for deep sleep, but less accurate for REM sleep. Despite its high price, the Fenix 8 may not be necessary for everyone, as cheaper alternatives like the Fenix 7 Pro or other brands like Coros and Amazfit offer competitive features. For those focused on health tracking, devices like the Oura Ring or Whoop Strap might be better suited.

- The Garmin Phoenix 8 exhibits inconsistent heart rate detection when cycling, with some sessions showing accurate readings and others significantly underestimating heart rates.
- Heart rate accuracy fluctuates, with readings often between 50% of the true rate and precise measurements, highlighting frequent detection errors.
- Performance variations between rides lack a discernible pattern, complicating predictability of accuracy.
- In comparison to other Garmin models, the Phoenix 8's heart rate accuracy is moderate, similar to the Phoenix 7 Pro and Epic 2 Pro.
- Lighter models like the Venue 3 and Forerunner 255 outperform the Phoenix 8, likely due to reduced motion artifact on the wrist.
- The Phoenix 8 is outperformed by the Pixel Watch 3, Huawei, and Apple watches in cycling scenarios, indicating room for improvement.
