A scuba diver can purchase many things for scuba diving at the Air Hog online shop. They can purchase dive knives, dive lights, dive computers, and dive bags which will help them in scuba diving.
Scuba divers require increased air pressures in their air tanks while diving because the pressure on their bodies increases.
Air...Sometimes Have Abit Of Oxygen In..But Most Of The Time Just Normal Air.
"Scuba scooter" is usually just slang for a diver propulsion vehicle (or DPV). It is basically like a torpedo with handles that a diver can ride. It enable the diver to go further, faster and using less air (because she gets less tired from swimming).
Anything pressurised with gas - an auto tire for example, or a scuba diver's air tank.
It depends on how deep the diver goes, and what air blend the diver is breathing. There are dive tables that state how long a diver can stay at a certain depth before requiring decompression. The basic recreational diver typically breathes either air or Nitrox. There are separate dives tables for air and Nitrox.
Free divers do but scuba divers do not need to. Scuba divers take their air with them and would have no need to hyperventilate.

The partial pressure of oxygen can be calculated by multiplying the percentage of oxygen in the air by the total pressure. In this case, 20 percent of 6.3 ATM is 1.26 ATM. Therefore, the scuba diver is breathing oxygen at a partial pressure of 1.26 ATM.
Literally, scuba diving means using diving underwater using Self Contained Underwater Breathing Apparatus.Conventional scuba equipment usually consists of a cylinder of compressed air (worn on the diver's back), and a "regulator" which converts the air from being highly compressed and delivers it to the diver at a breathable pressure.Scuba equipement also technically include rebreathers, which are a much more sophisticated form of diving equipment, whereby the air which the diver breathes is constantly recycled through a carbon dioxide scrubbing system.Scuba diving is now a popular recreational holiday activity, with over 10 million certified scuba divers worldwide.
Tanks are used to hold air like you breath above water. They do go thru a filtering process that removes the water and other things in air that can harm a diver. Scuba air from a reputable source is very clean and dry.
Have a decent amount of weights, or dump the air from the vest. Vice versa for staying on the surface.
