5.10. Safety Stops
Safety Stops are widely considered good diving practice for recreational and technical
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 HelO2 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 3–6 m/10–20 ft range. This is shown with the STOP
sign and a three-minute countdown in the center window instead of the no-decompres-
sion time.
