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 multidaydiving. When this isdetected, in addition toadapting the decompression
algorithm, the SuuntoRGBM model will in some circumstancesalso advise, with the Diver
Attention Symbol, that you extend your surface interval.
10.2.2. No-decompression limits
The no-decompression limits displayed by the dive computer for the first dive to a single
depth (see Table 10.1, No-decompressiontime limits for variousdepths (m) and Table 10.2,
No-decompression time limitsfor various depths (ft) .), areslightly more conservative than
those permitted by the U.S. Navy tables.
