@marbjo you might be right about surface time…
Also ive found in other groups someone mention the diferences between Ocean and Nautic S
***Thanks for your feedback! The Ocean and Nautic S have different features due to hardware differences. We’re always improving via firmware updates, but some advanced Nautic S functions may not come to the Ocean.
Keep your device updated, and feel free to share any feature requests!
The Nautic S supports dual transmitter for sidemount diving and be able to display simultaneously the pressure in each of two tanks.
The Suunto Ocean currently does not support simultaneous display of two tank pressures for sidemount diving. It can connect to multiple Tank PODs, but only the active gas’s pressure is shown. Unlike the Nautic S, dual‑tank display is not available on Ocean, and there’s no official confirmation it will be added in the future.***
