I have just finished reading Bret Gilliams "Deep diving". In the book he encourages to follow dive computers in air dives. (Very good book BTW.) We use finnish SUSL 92 tables downto 50m (165 ft) for all dives. These tables are more conservative than US NAVY: 42 m (140 ft) with 15 min bottom time gives deco of 7min/6m+ 10min/3m decos (10m/min asc speed) For same dive US NAVY has deco of 2min/3m (16 m/min asc speed). Computers typically go between these two. In repetitive dives with typical 4-6 hr surface time tables give significantly longer deco-times, computers give close to no penalty. Using this 2-dives-a-day style with "liberal" (from my SUSL point of view) BSAC 88 and dive computers have led to _very_ many "bend-hits" in Northern Scotland. It seems that these hits are related to repetive diving since they mostly appear after 4-5 days of diving. Dives typically are not very long, but it seems that decos are insufficient. We always dive following our tables. Does anybody use only computer info for this kind of diving? Any US NAVY users out there? Any opinions/comments? Any experiences?

Dive conservatively and enjoy every dive! -------------------------------------------------------------------
