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 decompression
algorithm, the Suunto RGBM model will in some circumstances also advise, with the Diver
Attention Symbol, that you extend your surface interval.
9.2.2. No-decompression limits
The no-decompression limits displayed by the dive computer for the first dive to a single
depth (see
Table 9.1, No-decompression time limits for various depths (m)
and
Table 9.2,
No-decompression time limits for various depths (ft)
.), are slightly more conservative than
those permitted by the U.S. Navy tables.
