It's been years since I have been here! And have a day of scuba coming up.
I booked some diving in Key West. But this is booked as 2 separate
tours, 2 dives in morning (Vandenburg! so 30m max) and a reef dives in >afternoon (10-15m I was told.)
They'll rent me a computer for the morning, but said I won't need on for
the afternoon.
By the book, the loss of computer is akin to forfeiting remaining diving
for 24 hours, unless you can reconstruct your PADI dive profiles and use
the good old RDP tables. (and I have seen a divemaster do that once). --snip--
Is there a way to use the computer's "desaturation time" to lookup the >residual nitrogen time on the PADI tables?
There's a more direct way. Almost all dive computers have a dive
planning mode.
Thanks. That is what my refresher course instructor suggested as well.
Since the dive computer can predict my max bottom time for my 3rd dive
at depth X, I can look for the Actual Bottom Time on the dive card
(back) for that depth and get the residual nitrogen and then continued
as per the good old fashioned dive tables.
Say I did a computer dive to max depth of 30m (100 feet I guess) for 30 >minutes (since I wasn't at 30m the whole time) and I still have spare
minutes by the time I end dive. (aka: did not exceed no decompression >limits).
Could I correctly assume that at worse case, I did a 20 minute dive at
30m (max time for that depth) ? That puts me in P ad can continue with card.
