5.8. Activation and pre-checks
This section describes how to activate the DIVE mode and explains the pre-checks
that it is highly recommended you perform before you get into the water.
5.8.1. Accessing DIVE mode
The Suunto Cobra3 has three diving modes: AIR mode for diving with standard air
only, NITROX mode for diving with oxygen enriched mixtures, and GAUGE mode for
use as a bottom timer and for freediving.
The OFF mode disables the DIVE mode, and allows the TIME mode to be used un-
derwater. The chosen dive mode is displayed when the DIVE mode is accessed, and
you can toggle between the submodes by pressing the UP/DOWN buttons.
