๐คฟ CCR has arrived on the Suunto Nautic!
A major software update for the Nautic brings dedicated CCR functionality to the computer, making this a significant step forward for technical and rebreather divers.
Rather than relying on the previous Algorithm Off approach, the new CCR dive mode is purpose-built for closed-circuit diving. The update adds support for CCR diluent and bailout gases, while increasing the maximum number of gas mixes from 5 to 8.
Setpoint management gets a serious upgrade too, with automatic or manual setpoint control, automatic setpoint changes and dedicated setpoint alarms during the dive. CCR-specific information is also available in the switch window, with relevant CCR data carried through into the dive summary afterwards.
For CCR divers, this is a substantial update and makes the Nautic a much more capable tool for technical diving.
The update is software version 2.55.46, released in August 2026, and is available as an over-the-air update through the Suunto app
One of the biggest Nautic updates yet โ and a very welcome move into dedicated CCR functionality. ๐๐ซง
