No-Decompression Limits For Air - Suunto VYPER AIR User Manual

Depending on the circumstances, Suunto RGBM will adapt the decompression oblig-
ations by doing any or all of the following:
Reducing No-decompression Stop dive times
•
Adding Mandatory Safety Stops
•
Increasing Decompression Stop times
•
Advising an extended surface interval (Diver Attention symbol)
•
Diver Attention Symbol – Advice to Extend Surface Interval
Some patterns of diving cumulatively add a higher risk of DCI; for example, dives with
short surface intervals, repetitive dives deeper than earlier ones, multiple ascents,
and substantial multiday diving. When this is detected, in addition to adapting the de-
compression algorithm, the Suunto RGBM model will in some circumstances also
advise, with the Diver Attention Symbol, that you extend your surface interval.

10.2.2. No-decompression limits for air

The no-decompression limits displayed by the dive computer for the first dive to a
single depth (see Table 10.1, No-decompression time limits for various depths (m)
and Table 10.2, No-decompression time limits for various depths (ft) .), are slightly
more conservative than those permitted by the U.S. Navy tables.
