Basic OPEN WATER certification starts at 10 years old. Below that you can have a POOL PARTY, and TRY DIVE experiences, along with bubblemaker dives as young as 8 years old. Be aware that the Pool Party, Try Dive and Bubblemaker sessions mean you MUST be escorted at all times by an Instructor or...
Get the Bends They get the bends; Nitrogen Narcosis. Nitrogen  bubbles form in the blood, which is a least painful and at worst,  fatal    INCORRECT - Nitrogen Narcosis is brought about by breathing  Nitrogen at depth and is resolved by coming up to a shallower  depth. The rest of the...
The reason you exhale slowly is to limit the risk of lung overexpansion injuries. The lungs are (in simplified terms) like a couple of balloons. When you inhale at depth, you fill them with compressed air. If you were to hold your breath and ascend, they would expand and eventually they would cause...
Tanks are usually filled from compressors, which simply pump in new gas until they reached the required pressure. Most dive shops have one or more compressors for this purpose. Sometimes tanks are directly filled from other tanks (called 'banks'), but that is usually when you need to fill them at a...
The best season to go scuba diving really depends on where you  located on the Planet.
60 feet is about 18 meters (the recreational limit for OPEN WATER CERTIFICATION) and the PADI RDP table states that 48 minutes will be the NO DECOMPRESSION time limit. Regardless of how much Air you still have in the cylinder, you MUST NOT exceed this time otherwise you will require a DECO STOP....
The name Open Water course is pretty much standardized in the industry for the beginning level course. But there are still some "lower level" courses (sometimes called a Scuba Diver course) in addition to the Open Water course. Just see which one give you more dives. You should get 4 to 5 scuba...
Helium is actually only rarely used in scuba tanks, and then only when blended with other gases (most commonl oxygen and nitrogen to make trimix). However, the main purpose of adding helium is to reduce the narcotic effects of other gases when you descend to greater depths. Breathing normal air,...
The theory behind this is that the hot water will raise your body temperature, thus releasing the gases that are trapped in the soft tissues of the body.(like bubbles in a soda bottle) This is dangerous in large volumes because those gases can form small bubbles in the blood stream. (The Bends / or...
It can be used as an introduction for commercial diving. The way to make a ton of money scuba diving is to start out with 2 tons of money! You can get a job at a resort. But the competition is fierce.
It is called a regulator. To be specific, the part of the regulator that goes in your mouth is called the second stage of the regulator.
  It is a device that looks like a bell and helps you dive into very deep places. the bell hosts the people in it sheilding them from the pressure.
  Its use was first described by Aristotle in the 4th century BC.   Guglielmo de Lorena created and used what is considered to be the first modern diving bell.

Most divers just use air - which is made up oxygen and nitrogen. Many dives are now being done with oxygen added to the air which is commonly known as enriched air or nitrox. Helium is also being used in diving gasses when divers go deeper. Other gasses have been experimented with and used, but they...
Most scuba diving courses can be completed in about 5 days or so. PADI's Open Water Diver course has an online portion or in-class work which takes a couple evenings, and two days of actually diving - SSI and NAUI have similar programs, but resorts tend to take a little longer than independent shops...
Equipment changes depending on the location of the dive and purpose. Basic equipment include, wetsuit, fins, snorkel and mask, lead weight, scuba tank, BCD (Buoyancy Compensation Device), and Regulator.
air resistance changes. But gravity stays the same.
Ruined? ... no. The correct answer here is you should go get your annual service done so it is inspected, etc. The first question I would ask is whether it is a piston regulator (you can look that up online through the manufacturer ... they look more elongated in general) or is it a diaphragm first...
Dive log is simply a record of the diving experience of the individual. Sometimes they are used to prove experience, or as a requirement for qualifications. However, more often they are simply a collection of memories that divers like to reminisce over.
The best old scuba divers trick ... yes for you guys too .... pantyhose. It is really thin and helps the suit just slide right on.
The Crush wetsuit provides a greater amount of flexibility with  anatomic cut, pre-bent knees, flatlock stitching and super flex  stretch kneepads for ultimate range of motion, and flex stretch  panels in lumbar, shoulders and under arms. The suit fits like a  glove and provides the insulation...
The body absorbs nitrogen at any depth. Due to the pressure as you go deeper, you absorb the gas quicker than if you were near the surface. These gas bubbles expand as you rise from the depths. A good example is to take a blown up balloon with you when you go swimming. Watch what happens when you...
You need to take an Open Water Certification course to become a SCUBA diver, but there are no pre-requisites. You actually only need to be 10 years old to enter PADI's first training program, and 14 for full certification, 16 for deep, and 18 for cave/cavern/wreck/search and recovery. However,...
Opinions vary, but personally, I would not dive in less than a 10mm wetsuit in water that cold. Otherwise you will have a very short and fairly uncomfortable dive.

Buoyancy control is one of the most important skills you will have to master as a scuba diver. On the surface while entering the water you do not want to be too heavy that you will sink while on completing your dive you have to maintain proper buoyancy control so as not to surface prematurely
Sir Edmund Halley is given credit for one in the year l7l7. There is some evidence Greek savants such as Archimedes toyed with all-glass diving bells but how much of this is wishful thinking is not known. the French hail Archimedes as the submarine pioneer, and have named several subs in his honor.
  we prefer to be called scuba divers but some may call us frogmen : )
This is mainly do to the pressure that the water above the diver is putting on the diver. On the surface air is putting pressure on you but it has less weight than water and as you dive deeper the pressure increases because the amount of water above you also increases.
The method is the same, but the formula differs depending on whether you want it in meters or feet. The easy method in feet is to add .3 atmospheres (ata) every 10 feet (or every 3 meters) and then add a surface atmosphere, so 20 feet would be: [(.3 x 2) +1] = 1.6 ata The simple formula for feet...
Strictly speaking, it depeds how high it will fly. If it stays below 2,000 feet, no reason to wait any length of time at all. If it will ascend to 8,000 feet (big helicopter) then protocols say you ought to wait at least 12 hours. Don't think there are any established protocols for the middle...

Yes. The chemical imbalance inside your brain when diving at deep depths and then returning to surface is proven to cause gaydom. (see msgt hall for further questions)
Many dive shops offer a two day program for the classroom and pool sessions, followed by a four dives done over two additional days. So the short answer is that you can become a certified scuba diver in four (sometimes less) days. How many years does it take to become a GOOD scuba diver, I'll leave...
you can scuba dive anywhere in Florida. google scuba diving locations to find a place near you. the most popular place is the keys. i would suggest you travel farther south in the Caribbean to dive.
It stand for "Visual Inspection Programme", and it means a dive professional taking the valve off the tank and inspecting inside to check for cracks or contamination. It is different from the hydrostatic testing that tanks are required to undergo every 5 years, in that the inspection is purely...
It is very good. It is popularly acclaimed as the best shore diving in the world, although all things are slightly relative. However the Netherlands Antilles have had a long standing a very successful marine conservation programme to preserve their underwater sites for the benefit of scuba tourism....
Diving is not normally a very lucrative business. Your biggest risk is usually bankruptcy. Contrary to popular belief, if done properly, diving is not a particularly unsafe sport.
Repetition can serve to really make the receiver of a message  analyze the words more closely. Also, repetition can offer  different perspectives on the same message, attaching contrasting  meanings and showing a new message altogether.
There are many reasons for stopping a dive. If you're running low on air, dangerous water conditions, cramps are also common on dives as well as the bends.
The method is the same, but the formula differs depending on whether you want it in meters or feet. The simple formula for feet is: (Depth + 33)/33 For meters it is: (Depth +10)/10
When diving, scuba divers breathe gas under pressure. The greater pressure causes the nitrogen in the breathing gas to dissolve in their bodily tissues (the body metabolises the oxygen). When the diver ascends from depth, the pressure is reduced, and so the gas comes out of the tissues and into the...

Each piece of equipment has a specific use and a specific way it  should be used. The safest and best way to learn is through doing a  PADI qualification, you can get all the equipment and PADI course  materials from watersportswarehouse.co.uk.
You don't. You can't dive this way. However once the tubes are removed (or absorbed ... I'm not a physician) and the holes heal (which they will), you should be able to dive. I say "should" since you probably need to know that the underlying problem for which you needed the tubes is also resolved....
SCUBA divers control their buoyancy to keep off the sea floor or from floating up to the surface, to avoid obstacles both above and below them, and to have a more relaxing dive with minimal physical effort. As a diver changes depth, they need to either add or release air from their buoyancy...
The first stage of the regulator is used to reduce the pressure in the tank to roughly 150 psi over the ambient pressure. It can then be sent down a hose built to withstand that lower pressure, meaning a smaller, more flexible hose. These hoses are used to supply air to the second stage regulator,...
Neoprene or polychloroprene is a family of synthetic rubbers that are produced by polymerization of chloroprene.[1] Neoprene in general has good chemical stability, and maintains flexibility over a wide temperature range. It is used in a wide variety of applications, such as laptop sleeves,...
There are several, already answered questions on this subject.Scuba-divers have to equilize their ears during decent, because the middle ear doesnt automatically pressurize (unlike other body parts, like sinuses).This is done by covering/squeezing ones nose using the thumb and index finger, and...
When diving, scuba divers breathe gas under pressure. The greater pressure causes the nitrogen in the breathing gas to dissolve in their bodily tissues (the body metabolises the oxygen). When the diver ascends from depth, the pressure is reduced, and so the gas comes out of the tissues and into the...
Suddenly increasing body temperature (through taking a hot shower or a hot bath) can expand gas bubbles in the blood stream which form when ascending from a dive, and can increase the risk of decompression sickness. However, unless the diver was really pushing the no decompression limits, or...
Most agencies will allow divers to be certified as young as 10. However, some require you to be 12. A few have the minimum age as high at 16 or 17, but they are unusual in this regard.
Both it was Jacques Cousteau and Emile Gagnan who invented the modern scuba gear in 1942.
more than a hundred,it depends on how many people are there in the world.
There are no exact numbers, but PADI, the largest diver training organisation publishes statistics on its certifications, and it certifies approximately 950,000 divers per year. However, only about 550,000 of those are new divers - the rest are divers who are already certified but who have received...
Going deep has several effects on a diver: The diver will consume her breathing gas at a faster rate, because each lungful of breathing gas is at greater pressure. A diver at 60 feet will breathe roughly 3 times as much gas as a diver at the surface. A diver at 130 feet will breathe roughly 5 times...
Scuba cylinders can hold large volumes of air (or other, more exotic, breathing gas), because the gas is compressed to very high pressures. If you're reading this in your living room on Earth, the air you're breathing is at "one atmosphere" of pressure. This pressure is often termed "1 bar" or 14.7...
It is any illness that is related to a release of pressure from the body such as barotrauma .. baro (pressure) trauma (injury). It includes decompression sickness, but it is not limited to decompression sickness. It is also not limited to diving even though that is what is mostly thought of when...
It really depends on what part of the ocean your in. If your in the pacific, then it might be a blue ringed octopus. One that I find the most plausible is a yellow coral that burns the skin.
There are no "side effects" as it is an inert gas just like nitrogen. While helium does have benefits, the only drawback (in addition to expense) is it can actually decrease the no-stop time limits.
So that the scuba diver could go more streamline in the water.
The Bends are caused by the formation of nitrogen bubbles in the blood stream. Theses bubbles form when the body is subjected to high pressure and that pressure is lessened too quickly. People who dive under water can get the bends in they surface too quickly.
The deepest depth that can be dived to (on air) and saturate and then surface without getting decompression sickness in general is about 20 feet (6 meters). This is known as the Minimum Bends Depth. Any depth greater than this depth can result in decompression sickness depending on the time...
  Red because it has the shortest wavelength. Then you lose orange, green,blue, violet.
by analyzing the experimental data it is clear that the relation of  gay-lussacs law is proportional to the volume of the given  substance. Therefore gay-lussacs law is related to scuba diving.
very deep like deep
It's Faire de la plongee, however, to specify that it is scuba diving and not snorkel diving, it's faire de la plongee sous marine.
 No one knows exactly how much pressure the  human body can withstand, but it is deeper than 1,500 feet.  
It is recommended that you wait 24 hours after scuba diving before you fly. Here is a passage from http://www.underwaterdivingequipment.com/scuba-diving-and-flying.html : "Expert sources disagree about how long you should wait before you fly. The US Navy says that 2 hours is all you need; the US...
As most commercial high altitude jets pressurize to about 7psi, or a little less than half normal surface air pressure (14.7 PSI), this increases outgassing of saturated tissues and, in borderline cases, may result in the Bends -- formation of gas bubbles in your boy's tissues.Modern dive computers...
Number one rule of Scuba diving is never ever hold your breath the pressure changes when you descend and ascend could damage your lungs. When ascending a diver does not need to just exhale they breathe normally unless they are using an emergency ascend in which case, depending on which emergency...
Use the Ideal gas law.   PV = nRT   Where:   P = Pressure (Pascals)   V = Volume   n = Number of Moles   R = Gas Constant - 8.314 (J / K*Mol)   T = Temperature (Kelvin)
they hopp in and zip up
It depends how rich the nitrox mix is. Generally speaking, a diver should not dive to any depth where the partial pressure of the oxygen in his breathing mix is greater than 1.4 ATA. You calculate the partial pressure by multiplying the fraction of oxgen in the gas (ie. 32% or whatever) by the total...
You could buy your own portable diving compressor, my dive buddy has one, there not silly expensive . You must get fills from a compressor designed for diving (breathing) as the air is filtered and moisture removed.
  Water has density and weight. The deeper you dive the more water you have pushing against your body.   == Answer ==   Think of it like this young padawans:   You place a book on your head, no big deal. For every foot that your imagination takes you deeper on a dive add one book. Is...
There are no legal requirements to scuba dive. In other words, anyone can scuba dive without breaking a law (assuming you are not doing an illegal underwater activity such as illegal fishing). However, if you are not certified, you will not be able to rent or buy equipment or get someone to fill...
Diving gases which are used (in order of frequency in everyday use): Most scuba dives use conventional air as a gas mixture.However, some divers use nitrox, which is oxygen enriched air. The increased oxygen content (well, actually it is the reduced nitrogen content) allows divers to stay underwater...
Two French men, Jacques-Yves Cousteau (June 10, 1910-June 25, 1997) and Emile Gagnan (November 1900-1979) invented the Aqualung in 1943. It was the first open-circuit free-swimming underwater breathing set. . Jacques Cousteau amd Emile Gagnan. It was invented in 1943 by Jacques Yves Cousteau and...
The deepest free-dive on record with AIDA International is 88 metres, which was obtained by William Trubridge in 2009 in 3 minutes, 30 seconds.
The certification levels for PADI (Professional Association of Dive Instructors) are as follows: *Junior Open Water Diver---minimum age of 10 and the diver cannot go below 45 feet *Basic Open Water Certification--minimum age of 12 and the diver can go to the safe distance of 132 feet*Advanced Open...
  Yes. Not sure on the exact weights (as it depends on size of tank and pressure of the gas) but you can tell a definite weight difference between an empty and full tank because the compressed air does have a weight

There is absolutely no law against it. I would hate to see it happen though because 99% of scuba instructors are married.
Depending if the person is nitrox certified or not the gas in the tank is compressed air or if nitrox certified the gas will be a mix of nitrogen and oxygen with the mix marked as a percentage of O2.
A SCUBA diver will want to descend as quickly as possible in order to get to their target depth having absorbed as little nitrogen as possible. However, the diver needs to continually equalize the pressure in his or her ears to prevent discomfort or damage to the eardrums. How easily the diver can...
It has changed in many ways, from crude equipment to allow a person to breathe underwater in very shallow depths to modern equipment which allows a diver to reach great depths, relatively speaking. Go to the Related Link to read about the History of scuba:
According to the sport governing body (AIDA) Austrian freediver Herbert Nitsch in Greece June 2007 reached 214 metres. Herbert Nitsch holds world records in 5 of the 8 free dive disciplines. See the related link below.
