Garmin has launched the latest models of its flagship Fenix adventure watch, with the Fenix 9 and Fenix 9 Pro set to go on sale on Friday, August 28.Both look fantastic, with upgrades to the design and software that include the largest screen ever on a Fenix with the 51mm models, full titanium cases on the Pro models, and a faster mapping experience.While the Fenix 9 and Fenix 9 Pro might be the best Garmin watches available, you may get better value by opting for an older model, with the Garmin Fenix 8 and Garmin Fenix 8 Pro both reduced right now. The Fenix 8 Pro is down to $949 at Amazon, while the Fenix 8 is down to $849 at Amazon.New features are rolling back to the Fenix 8 and Fenix 8 Pro
