Hi all,
Not sure if this is the best section of the boards for this query, but here goes.
2nd post regarding my trip to Komodo National Park, Indonesia over Christmas, and there were 2 scenarios I found problematic here. I'll post them separately
I'm a PADI OW diver, some 35ish dives.
One particular dive, there was a large rocky overhang we were exploring underneath for some time. I did find now and then that I'd seem to start rising and I'd become worried that I'd crash into the overhang and I'd be desperately dumping all the air from my BCD - I don't recall if I had been adjusting my BCD at this point; I do know that I sometimes seem to find that by BCD goes from neutral to negative, and I guess I don't have the experience to know if that I'm doing something (ie unintentionally finning up to make me think it's neutral when it's not)....
of course if I had put air in my BCD and 30s later I was about to headbut the o/hang that's self explanatory, but say I wasn't adjusting the air.....any advice in this sort of situation? would the variation of even a metre of two in depth exploring the area be enough to cause the expansion of BCD air causing an unexpected rise, or am I doing something else wrong here, or is there some way to manage these environments that I'm not aware of?
