I do love my S95 and I am slowly getting into underwater photography / video.
However its not uncommon that some point during dive 2 I can run into a low battery situation and then it runs out meaning that I am now hauling a useless lump with me. This has frustratingly happened a few times just before I see a great subject.
I was under the impression that it is best to try not to open the housing between dives but I do have a spare battery so considering it to avoid the above situation. TDFers, what are your thoughts / tips on this front?
