Im also never going in again without SIGNIFICANTLY more air even if I dont plan on using it. Those tanks only filled to 2400 were only holding about 88 - that plus the short filled 19's and I was not carrying enough. I should have rented when they said they wouldnt fill past 2400 - but then again, knowing that sharks and current can come out of nowhere, I probably should have turned the dive quicker. I felt what I guess was a false sense of security knowing the anchor line was so close.
At home I get my LP95's filled up to hold 118 of air - that plus the 30 (a full 30 instead of a short 19) with verified pony numbers should do the trick. Im also looking at a couple HP130s for deeper dives. Maybe, Maybe - I might turn my LP 95s into doubles - but I doubt it.
