Well I do not know anything about diving but it would be cool to spend your holidays with everything safe to dive, it would be a good idea to bring a few companions, a selfie is not bad after all but I have a question, how can you make a selfie under water ? Or how can you take pictures and tax underwater with smart phone? I say, I ask why I have never seen something like that, and if it can be done, then I would like to see it because its diving devices are a bit worn but it is also used and you can take advantage of it.
