Underwater Housing - a simple approach

there are just two buttons - doesn't get much simpler
(but I think it's a bit too simple/ basic)
1 - presses the camera's on/ off button
2 - half pressed the other focuses the shot and...

fully pressed, it takes the shot
the housing feels strong, the opening and closing lock is easy but secure
its not leaked with me - the side grips are good and it takes several different models of camera
(is a SS-2 model which takes several others)
for robust, simplicity - this is for you
but a housing giving access to the zoom button and the flash button is much better
