Cobalt: Settings: Preferences

The User Preferences screen allows for entering an owner name, setting the frequency for the storage of data samples during a dive, and setting the unit preferences for display of data.

Depth can be set to feet or meters.
Pressure Units can be set to PSI or BAR.
Volume Units can be set to cubic feet or to liters.
Temperature Units can be set to °F or °C.
Dive Log Data Storage controls the frequency with which the Cobalt computer "remembers" a snapshot of your dive data. At the default frequency of 30 seconds the dive log will hold about 600 hours of diving. Selecting a frequency of 15 seconds would reduce this by half.
