How right I was with my considerations, was confirmed on 17.7.2011, during a snorkeling gear, outdoors, on the outer reef. When bitten, I have my new IXUS course never simply slid into the bag, but she put on a bright, narrow strips of hard rubber. That was my luck! My custom and regular inspection look into the bag revealed a water break and only the rubber strip is due to that it did not cause a short circuit immediately. With the camera in a bag on his head I snorkeled back to kilometers, which I "only" lame arms prepared, but saved my camera.
I have checked the bag and allow to run full of water. As the water level rose over the additional Velcro, ran up the left smallest droplets from and to the bag shut. The outermost end of the Velcro strip Einpressstelle had come loose, a tiny hole was created, through which the water could seep slowly while snorkeling.
As I said, rather than to manufacture the bag as smooth as possible, possibly add a second, good Zip, received the bag a predestined for fatigue, because pressed Velcro, which is of course always under tension. That must really not be!
