Scuba divers use pressure meter because the deeper down you go the more pressure builds up

a depth gauge or a dive computer

Is scuba diving a type of science?

The best answer is probably no. Safe scuba diving relies heavily on a knowledge of physics, gas laws and even physiology. Since it generally takes place in the ocean, it often involves marine biology. In that respect scuba is far more reliant on science than most other activities. Generally, though, scuba is a recreational activity for most divers and a vocation for others.

Is scuba for fun or money or both?

Its for both. You can do it for adventure or fun. But, while diving, you may find some hidden treasure also. EDIT! Dont touch hidden treasure!! Thats a BIG no no as far as a lot of divers are concerned. The items and life in the sea are there to stay! leave them for other divers to see as well. Unless you are on a specified archeological or Recovery program, DONT bring items from wrecks back!

How deep can a technical diver dive?

Divers have dived over 1,000 feet on scuba (rarely - only four times so far), so that is probably the outer edges of the limit for technical divers.The deepest level you can be 'certified' to dive at is 330 feet/100 meters (TDI Advanced Trimix/IANTD Expedition Trimix). Wrecks like the HMHS Brittanic and the SS Transylvania are dived with some degree of regularity at depths around 450 feet.But there are no scuba police, and many technical divers in fact exceed those depths regularly. The deepest depths to which technical divers are known to dive with any level of regularity are around 550 or so feet (thinking of the Jolanda in the Red Sea at various depths down to and slightly below 550 feet).Dives below 600 feet are extraordinarily rare.

What is free diving?

free diving is where a group or one person goes into the sea and dives; without a oxygen tank. they then proceed to go as far down as they can and the one who goes the furthest down wins. free divers are required to have a good lung capacity and as healthy body, it is advised NOT to try this, free divers are proffesionals and have had many years of training. Many risks can be taken for example; too much pressure on your heart and body causing breakages, heart attacks and of course drowning. It is advised that you have a doctor or someone with a medical qualification to be present at events to ensure the safety of free divers.


Is oceanography mainly scuba-diving?

Oceanography is like geography in the sea. You study the geography of the seabed and the nature of the water, such as salinity, turbidity currents etc. Although oceanographers may like scuba diving it is unlikely that is will be part of their job because using SCUBA you can only visit a tiny amount of the oceans. Lots of oceanographers are involved in oil exploration for example where the water would be far to deep to reach with scuba.


Can a human go down as far as the titanic sank down to reach it?

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.
