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.
