Can't you swim? Can you take scuba diving lessons?
Swimming and diving are different, ah, diving equipment, ah, of course, you can report ah, but for safety, it is best to first learn swimming lessons, not afraid of 10000, in case ah!
And some people are not used to breathing by mouth, careless use of the nose to choke water, it will panic. Reported the course to study well, when you can dive, also can swim probably ~ my colleague is such!
If it's the kind of back oxygen bottle, it doesn't matter. No, swimming is fine. But some people are afraid of water, especially in the sea water, there will be a sense of weightlessness, helpless and boundless,
In fact, you do not have to swim, but personally think snorkeling can swim, it may be more fun.
