SFK-7 II Photo and Movie Underwater Camera

I sow camera like this on eBay ones. Looks very interesting and complicated! Great item to have! How heavy and big this camera? Can it be converted to work from outlet?

I think we already had discussion about this camera some time before, from what I remember vaguely it was established that it was used for taking movies of underwater scuba exercises and not necessarily used on submarines, just underwater in like a scuba diver training pool.
