I became a certified PADI Open Water Diver yesterday. In Puget Sound. In December. Headed for Cozumel next month. Go me!
PADI says the Controlled Emergency Swimming Assent should not be used from depths greater than 30 feet. This raises some questions in my mind. First, just exactly what is someone supposed to do if they run out of air at 100 feet of depth and an alternate air source is not available? I guess the only alternative to dying would be to exceed the safe assent rate and just get to the surface. Am I missing something here?
I also know that running out of air does not just happen by accident. It should never happen.
Here is another curiosity: What do free divers do? We've got a free diving depth record of more than 800 feet. Do free divers hold their breath until they actually return to the surface several minutes later? Are they not risking decompression sickness?
Thank you, in advance, for considering my questions.
