Unlike the U.S. Navy tables, the
IQ-400
interpolates between depths, giving a
diver “credit” for time spent in shallower water, rather than calculating no-
decompression limits based on the maximum depth of a dive. As a result,
multi-level no-decompression dive times permitted by the
IQ-400
are often
