Safety Stops And Deepstops - Suunto D4I User Manual

WARNING: Traveling to a higher altitude can temporarily cause
changes to the equilibrium of dissolved nitrogen in the body. It is
recommended that you acclimatize to the new altitude by waiting
at least three (3) hours before diving.

3.17 Safety stops and deepstops

Safety stops are widely considered good diving practice and are a
critical 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.
Suunto D4i displays two different types of safety stops:
recommended and mandatory.
With every dive over 10 meters (30 feet), there is a three-minute
countdown for the recommended safety stop. This stop is taken in
the 3-6 m (10-20 ft) range. Suunto D4i shows a STOP icon and a
three-minute countdown.
