How deep can a human go without a scuba suit?

Answer 1

we shall never know until someone answers the question? Another answer Scuba is the acronym for 'Self-Contained Underwater Breathing Apparatus'.

FREE DIVING: The deepest anyone has gone (and returned!) without special underwater breathing apparatus is 214 meters (2007). However, the whole business is fraught with danger and controversy. The main limiting factor is the how long a person can hold their breath whilst swimming. In this particular case the diver, Herbert Nitsch, went down on a weighted sled and was pulled to the surface by a lift bag he inflated. Obviously a human without special breathing apparatus can go much deeper than 214 meters, but the likelihood of them returning alive becomes more and more remote the deeper they go. * For more information see Related links below this box
