Re: DIY - discussion on building a DIY hookah diving compressor
Not related to last post, just a thought:
When you free ascend you take in air at sea level so it would be impossible to cause issues like you would see with tank or hookah diving. I think that is the biggest risk with hookah diving without a diving cert, you really need to understand the problems that can occur if you hold your breath on ascent. My dive instructor did the classic example of a balloon filled at depth then released to the surface. It got the point across well.
