Nice photos. So how many shots did you do during your dives? I typically average about 100 to 120 per dive on my last few trips out, which is why I'm a little concerned that I may be hitting the limit on a longer day without doing a battery swap. I like to do a lot of macro work and will often half a dozen or more shots of the same subject with varied exposures and angles to try to get the best shot I can which can add up to a lot of shooting when on dives with a lot of subject matter to work with.
I shoot almost as many shots as you do (many with the onboard flash, no slave strobes) with a G10. In Bonaire, doing 4 dives a day, I ran out of juice early into dive 4 the first time. So I started swapping out batteries and cards at lunch time every day.
So just a data point, but for you the G11 may not have any benefit for your shooting style. And do you really want to "hope" that your battery will make it through that last dive?
