Before a diver dives will he will take a deep breath or hyperventilate?
Free divers do but scuba divers do not need to. Scuba divers take their air with them and would have no need to hyperventilate.
Are scuba divers fat?
Generally no. They need to be quite fit to be able to swim in the water :)
Why do scuba divers need math?
they need to know how long they can be underwater, and how deep they can go with the air in the tank.
Why do scuba divers need decompress?
If they don't then small bubbles can form in their blood, and in some severe cases it can kill them.
Why does a scuba diver need increased gas in the air tank?
Scuba divers require increased air pressures in their air tanks while diving because the pressure on their bodies increases.
Why do scuba divers need to bring oxygen tanks while fishes do not?
Because fish have gills and can breathe under water and humans do not
Why do people use air?
We need air to breath. Otherwise we would suffocate and die. That is why scuba divers have special equipment to allow them to have air to breath underwater.
How long does a scuba diver go to college?
Recreational scuba divers only need to undertake a short course to be qualified (or "certified" using industry jargon). The certification process for a basic open water diver normally takes about 5-6 days.Commercial divers usually undertake some kind of vocational training, but this is not usually done through a college or university.
How old do you have to be to get a scuba diving license?
Kids as young as 10 years old can enroll in Junior Open Water courses and those 15 years and older can enroll in an Open Water course. When offered, Junior Open Water (diving with adult supervision only) certified divers are automatically upgraded to Open Water divers on their 15th birthday with no need for re certification. This can vary depending on the certification agency involved. You'll also need to be in good health with no major health problems.
Age to get scuba certified in GA?
You don't need a licence to go scuba diving, but most people need to undergo formal training before they can scuba dive. Different agencies will take divers at different agencies, but the bigger agencies will usually not train anyone younger than 10 years old. However, some agencies insist that a student be 16 or 17 before learning to dive.
What element do scuba divers need to prevent the bends?
Scuba divers need to decompress after a deep dive so that the oxygen levels in their blood return to normal before returning to the surface. Otherwise they will get the bends. A scuba diver will typically use his or her dive table or computer to figure out how many minutes they must decompress before resurfacing from the dive. Decompression takes place when a diver figures out the amount of time they need to wait at a certain depth under water before they can resurface. They also need to take into account how much air they have left so they can safely wait underneath the water for said period of time. A scuba diver will usually hold onto a drop line and simply breath and wait the allocated amount of time at the prescribed depth and only then safely return to the surface.
Why do you need oxygen cylinders when you go scuba diving?
The simple answer is ... you don't. A majority of scuba dives use compressed air in the cylinders. Therefore you don't need "oxygen" cylinders. HOWEVER, if you are a diver that is diving on Nitrox, in which divers change the amount of oxygen vs nitrogen in their air, then your tank needs to be "oxygen clean" because you are putting oxygen in first, then nitrogen.
