For my honeymoon, I purchased this camera for scuba diving photos (because of its flash) and 2 cheaper Kodak disposables without flash for beach and snorkeling pictures. The SharkDiver camera was horrible. The film advance was difficult to turn, the shutter was hard to push down, the flash didn't always function, and on and on. Then, worst of all, the casing apparently leaked and after going to all that trouble to take a full roll of pictures, we ended up with 4 discolored, double exposed pictures and none of the others came out at all. On the pictures we did get, the use of the flash didn't seem to matter at all -- they were still pretty dark.The Kodak cameras by comparison were great. They were easy to use and produced good pictures in spite of not having a flash. I used them on several pictures at ~20-25 feet under and had plenty of natural light for a good picture.
