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 in-
clude: reducing sub-clinical DCI, microbubble reduction, ascent control, and orientation
before surfacing.
The Suunto D4 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 Recommen-
ded 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-de-
compression time.
