Here: Descent, Garmin’s next Fenix4 model? there are interesting info and also link to attempts of putting diving oriented app in the previous Garmin model (that were discouraged by the Garmin itself to not incur in problems because the model was not designed for such use).
The next Garmin model could have bypassed such limitations just adopting a better pressure sensor and buttons that can be used under water).
