Every person is different but free diving requires a lot from a diver. It isn't a sport you just jump into and go. It is a progression that requires a lot of time and training. It isn't for the recreational diver. There is no right answer. It's similar to how many G's a person can stand, it comes down to how bad one wants to try.
scuba divers use pressure meter because the deeper down you go the more pressure builds upAdditiona depth gauge or a dive computer
You can if you have a Boat and enough oxygen. Do not go to far down or when you try to come up you'll have no oxygen.
Technically, air pressure (surface atmospheric pressure) affects a scuba diver the same regardless of the depth. As far as total pressure goes, no diver has been to 1500 feet.
Experts recommend to never SCUBA dive past 150 feet below the surface of any body of water.
16 Feet
Only in a deep-sea submersible- certainly no scuba diver can dive down anywhere NEAR that far, as she lies at such a massive depth. The Titanic wreck is 2 and half MILES down on the floor of the North Atlantic, where the water pressure is over 2 tons to the square inch- no diver could survive such colossal pressure, and in any case, it would take them so long to swim down there that their oxygen supply would run out before they got to the bottom. The furthest down a scuba diver can go is about 500 feet.People can only reach the wreck site in special deep-sea submarines, that are specifically built to cope with the extreme conditions, such as the submersible Alvin that was used by Dr. Robert Ballard when he discovered the wreck in May 1985.
250 meters
Yes you can swim. It would not be a good idea to scuba dive or snorkel to far below the surface of the water.
100'
A giant squid can dive about 5 miles down. Nobody really knows quite how far a squid can dive.
The world record for a scuba dive (without protective gear, beyond a wet suit and oxygen tanks) is approximately 1029 feet. The immense pressure which builds exponentially as an object descends is sufficient to crush humans at a lesser depth, in many instances.
