Important fēnix 9 Pro Notice
Garmin states that metal watch bands, and bands with metal parts that contact or sit close to the watch housing, should not be used with fēnix 9 Pro because of possible interference with GNSS, Bluetooth, Wi‑Fi, LTE and satellite-connected features. Garmin also advises using supported non-metallic Garmin bands for that model.
Therefore, LDFAS titanium/metal bands should not be presented as recommended bands for fēnix 9 Pro. This is a manufacturer safety/compatibility warning and should take precedence over a connector-size match.
