Table 8.2 No-decompression time limits (min) for various depths [ft] for the first dive of a

series.

Unlike the U.S. Navy tables, the Spyder interpolates between depths, giving a

diver “credit” for time spent in shallower water, rather than calculating no-decom-

pression limits based on the maximum depth of a dive. As a result, no-decompres-

sion dive times permitted by the Spyder are often much longer than those that

would be allowed by the U.S. Navy tables.
