Just in case you're interested, maybe it's not as cool as the original one, but the kingma seems to be giving good results. I am yet to try it on a diving trip, but some contacts have been testing it lately for that purpose and it seems to work as expected. Only issue was it fogged up while diving due to temp difference, but that seems to happen with most (if not all) action cameras and it's easy to solve, either using silica gel bags inside the case, or with a homemade solution , wrapping the camera with tin foil (except the front and the lens) so condensation remains on it.
