The Suunto Cobra2 also allows experienced divers who are willing to accept a greater
level of risk to adjust the RGBM model. The default setting is 100%, which gives full RGBM
effect. Suunto strongly advises you to use full RGBM effect. Statistically, very experienced
divers have less incidents with DCI. The reason for this is unknown, but it is possible that
some level of physiological and/or psychological accommodation can take place when
you are very experienced as a diver. Thus, for certain divers and diving conditions, it may
be desirable to set attenuated (50%) RGBM mode. See Table 5.6, RGBM model settings.

5.10. Safety Stops
Safety Stops are widely considered good diving practice for recreational diving, and are
an integral part of most dive tables. The reasons for performing a Safety Stop include:
reducing sub-clinical DCI, microbubble reduction, ascent control, and orientation before
surfacing.
The Suunto Cobra2 displays two different types of Safety Stops: Recommended Safety
Stop and Mandatory Safety Stop.
5.10.1. Recommended Safety Stops
With every dive over 10 meters, there is a three minute countdown for the Recommended
Safety Stop, to be taken in the 6 - 3 m/10 ft - 20 ft range. This is shown with the STOP
sign and a three-minute countdown in the center window instead of the no-decompression
time.
WHEN STOP IS DISPLAYED,
MAKE A RECOMMENDED SAFETY
STOP FOR 3 MINUTES.
NOTE The Recommended Safety Stop, as the name implies, is
recommended. If it is ignored, there is no penalty applied to the
following surface intervals and dives.
