Which bands should you avoid on a Fenix 8 Pro?
Garmin warns against metal bands, bands with metal parts near the case, and third-party bands on the Fenix 8 Pro, because they can interfere with satellite, GNSS, Bluetooth, Wi-Fi and LTE signals. The warning names the Pro, not the standard Fenix 8.
Do Fenix 7 and Fenix 9 bands fit the Fenix 8?
Yes, at the matching QuickFit size. Garmin lists QuickFit 22 for the Fenix 7, Fenix 8 47mm and Fenix 9 47mm. QuickFit 20 fits the Fenix 7S and the 43mm Fenix 8 and 9, and QuickFit 26 fits the Fenix 7X and the 51mm Fenix 8 and 9.
