I've used the Kodak version of an underwater "disposable" for years.
Supposed to go to 12 feet, I've taken them to 40 with scuba. They don't
implode, but you have to come back up to 12' to advance the film. This
new camera sounds much better. But even the Kodaks are better than the
Fuji version which claim to go to 12', but leak if they so much as get
wet.
