It might not occur to you now, but go on a dive with a camera in a housing holding it or having it clipped to your BCD.
Even if it isn't intentional, I reckon you will probably bang it around a little, whether it be on your cylinder or the seabed.
Also, using a housing means you get a much better view of the controls and such. I have to say, they are somewhat expensive. Getting one for my compact camera would cost only a touch less than the actual camera. |
