Summary: I have just returned from holiday and as far as the camera is concerned it was a complete disaster. On the first snorkel the camera failed. Being an experienced amatuer photographer I took every precaution as laid out in the product manual,The first thing I found was that the camera would not turn off. When I returned to my boat I checked the camera and found there had been no water entry and it would still not turn off. Then the screen disapeared completely.
