Scuba Diving Tips: Breathing Control

Breathing is easy, isn’t it? We do it all the time. Good air in, bad air out. Simple, and easy, right? Wrong! In scuba diving, breathing properly serves three major purposes, and missing out on knowing how to breathe properly can lead to a messed up dive.

Why should your learn a different way to breathe for diving? Well, the technique that will be given here isn’t just for diving, it’s meant to increase the efficiency at which your body processes oxygen in general, and will benefit every aspect of your life that requires physical activity.

First off, proper breathing helps you to control your buoyancy. If your scuba instructor tells you to hold your breath while adjusting your regulator to control your dive depth, you’ll quickly wind up blue in the face. Definitely not a pleasant experience. Instead of holding your breath and relying on the weights and regulator to adjust buoyancy, breathing properly can cause subtle shifts in your floatation.

Secondly, proper breathing on a dive extends your air time. The breathing technique given here helps the body process more oxygen, sending it to the body with greater efficiency and maximizing the amount of oxygen that gets introduced into the blood stream. You won’t use your air up as quickly, and can extend your time underwater.

Lastly, proper breathing combined with good control over your descent and ascent rate helps to minimize decompression sickness, which is a problem that hits divers when the sudden changes in external pressure on the body trigger collections of air pockets in the blood stream, heart, and sinuses. Those little air pockets cause a condition that divers refer to as The Bends, which can be anything from merely painful and annoying, to outright fatal by leading to a stroke or brain damage.

That said and done, let’s get into the actual breathing method to use.

Speaking from personal experience, the breathing technique that should be employed in diving are related to that used by martial artists, singers, yoga practitioners, and gymnasts. This is a method called diaphragm breathing, and goes by many different fancy names depending on which discipline is using it, like in martial arts where it is referred to as Ki or Chi Breathing.

To practise diaphragm breathing, either stand or sit up straight (your choice), and just breathe in. Don’t slouch. Observe how you take the air in. Most people will have their chests expand when they take a breath. This is normal, regular lung breathing. In diaphragm breathing, the lower stomach expands instead of the chest.

To do this properly, the biggest key is to relax. Your abdominal muscles will actually instinctively tighten up when you take a breath and try to focus on your gut. Don’t focus on your gut, just relax and breath in, but make a point of actually relaxing your navel area when you inhale. Most people get diaphragm breathing wrong because they tense up the muscles in their gut in an effort to send their breath there. Tensing up these muscles actually causes them to contract, which keeps air from going that deeply. That’s all there is to this form of breathing, really. It’s simple, once you get the hang of it.

It’s also important to keep your breathing rhythm deep, slow, and even when you’re practising this method, inhaling as far as you can go, holding the air in your lungs for just a few seconds, then exhaling the air slowly and evenly. Shallow, rapid breathing, as most medical practitioners know, is a very, very bad thing, which leads to asphyxiation, a state where not enough oxygen gets cycled through the body.

By the way, the air, of course, isn’t really going into your stomach. It just expands because the diaphragm is positioned right above it in the body. Basic anatomy lesson here: the diaphragm is a membrane which controls the expansion of the lungs, which causes the inhalation and exhalation of air. Basically, what this form of breathing achieves is to strengthen your diaphragm itself, as well as increasing the capacity of your lungs. Keep practising this method until it becomes automatic and natural, and you’ll be surprised at the results. Not just in your scuba diving, but in your overall physical condition.

Scuba Safety Measures

Scuba Diving, while fun, has it’s share of hazards like any outdoor sport. Knowing how to recognize and deal with potential problems before (or when) they occur can make the difference between life and death when you’re under water. Here are a few safety precautions to take, as well as some of the things that can happen that you should look out for.

Plan Contingencies for Every Emergency - there’s that law good old Murphy made, that “Anything that can go wrong will go wrong”. While a seemingly pessimistic and cynical statement, it actually helps sometimes to take this approach, especially when planning for emergencies. Take enough gear to handle all the potential problems that you’ll encounter, and have back up means of getting external help on hand in case something arises that you weren’t prepared for.

Decompression Injuries: DCS - know how to recognize the symptoms of these two maladies. They will require treatment in an emergency decompression chamber. They are: Decompression sickness, or DCS, and Cerebral arterial gas embolism, or CAGE. DCS occurs because the body forms air pockets in it when utilizing compressed air, as well as becuase it is subject to increased external pressure from the water. DCS occurs because the nitrogen in a person’s air supply, unlike oxygen, is NOT used up and absorbed by the body, and the increased levels of nitrogen, unless controlled by a device on the breathing apparatus called a regulator, collects air pockets in the body. These create a cramping sensation, nausea, and lightheadedness, and a physical sensation referred to by divers as The Bends. DCS usually occurs on an overly fast descent, as the body and the regulator can’t compensate fast enough for the increased water pressure.

Decompression Injuries: CAGE - Cerebral arterial gas embolism occurs more often as a result of an uncontrolled rapid ascent, as opposed to the bends that hit divers due to a fast descent. This manifests as sharp pains in the body, especially in the sinuses, head, and in the lung area. This is a very serious condition that can be potentially fatal. CAGE is caused when the rapid ascent of the diver causes air bubbles similar to those formed during DCS, only this time the air pressure changes that trigger the bubbles in the body are due to a sudden lessening of the water pressure surrounding the body. This causes the trapped air to have a higher pressure volume than the surrounding atmosphere. In effect, the diver is an unopened can of soda that got shaken real good underwater, and once he leaves the water, it’s the same effect as opening the can…

Injuries - the injuries that can occur from decompression range from the merely bothersome, like nausea, sharp pains, and cramps, to more serious matters. One of the most potentially damaging is trapped air bubbles reaching the heart or the cerebral system. As some of you may have seen on television, there are episodes where a villain kills a sleeping victim in a hospital by injecting air into their dextrose. The air bubbles formed in the veins cause cardiac arrest when they hit the heart, or a stroke when they hit the brain. This is a true fact, and the air bubbles causes by decompression may have this effect, if large enough. This is one of the major reasons why controlled ascents and descnet rates are so vital to safe diving.

Other Potential Maladies - aside from decompression sickness, which is the most common and severe type of injuy incurred by divers, other maladies are mostly atmospheric in cause. Hypothermia is caused by dives in extremely cold water, or by diving with a wetsuit that doesn’t provide enough heat insulation. Dehydration also occurs on a dive, surprisingly. Be sure to drink lots of water before you go. Asphyxiation occurs, on the other hand, if the air supply used is flawed and doesn’t give the body adequate oxygen to function.

Scuba Lifesaving - Take up a first aid class that will allow you to recognize the signs of the conditions given above, and also teaches you emergency measures to be used in those events. Don’t rely on text based or verbal descriptions, make sure that the first aid course gives you full, hands on training in dealing with these injuries. Also keep your first aid kit handy and well stocked on your dives, and always have a means to call for help from others, including a radio transmitter, cellular telephone, and even signal flares. While seemingly bulky and unnecessary, these items can mean the difference between life and death.

Observe Marine Life Through Skin Diving

For centuries, people have tried to explore the aquatic environment. Before, their main reason was to gather food or to salvage some items from rivers, lakes and oceans. Also, young girls and boys were trained to free dive to gather shellfish and seaweed, and even sponges from the sea floor.

In modern times, although people still continue to dive for valuable objects and food, diving’s popularity grew especially in warm vacation destinations. Tourists and diving enthusiasts skin dive to explore the underwater world. Without any special training and equipment, they were able to observe the beauty of aquatic life.

Basically, skin diving is defined as a water activity wherein swimmers depend on their lung capacity, a diving mask, snorkel, and fins to move about underwater for several minutes. It is an extension of snorkeling, where a person views the underwater environment from the water surface.

Skin diving is termed as such because of the little equipment it requires. Its basic requirements are only a waterproof mask, fins for the feet, and a snorkel. A snorkel is just a tube about 38 cm long with a mouthpiece on one end, used for breathing underwater.

The diving mask should allow the skin divers to see clearly even when underwater. A mask which completely encapsulates the nose and eyes to form an air space between the water and diver’s eyes is preferred.

Fins, or also called flippers are like the webbed feet of a duck. These enhance the divers’ movements below the water, and helped to propel them in a smooth and efficient motion. All fins have a foot pocket to secure your feet in, and large sheets of flexible plastic.

Snorkels are also helpful in observing shallow marine life. As long one end extends out of the surface, the diver will be able to breathe normally. However, snorkels shouldn’t be more than 15 inches long since air can’t be drawn to greater depths.

If you want to go deeper into the water, you have to hold your breath. Since you can’t possiblily live without breathing for hours, you could only stay beneath the ocean for brief periods, usually about two minutes. Experienced skin divers, however, however are known to stay underwater for several minutes.

The main difference of skin diving from scuba diving is the device used by scuba divers. Scuba stands for “self-contained underwater-breathing apparatus”, which is basically just a metal tank filled with air. This tank should be connected to a valve regulator for pressure adjustment so the diver can breathe comfortably even at greater water pressures.

Also, since scuba diving involves exploring the water at greater depths, there are other major considerations. A scuba diver needs a suit to keep him warm enough while underwater.

Scuba divers also make use of buoyancy compensators to help them control their position while underwater. A diver just controls the amount of air in these buoyancy compensators to adjust their overall buoyancy.

Of course, there are several pressure related injuries which a scuba diver is exposed to. Ascending or descending too quickly causing significant rapid changes in the pressure difference between a diver’s body and his surroundings may be fatal. That’s why, scuba divers need to go through specialized training to be able to stay safe and remain alive even when more than a hundred feet below water.

That’s basically the difference between scuba diving and skin diving. When you scuba dive, you are largely dependent on your diving gears for survival. Skin diving on the other hand is a simpler form of exploring the underwater environment, that’s probably what makes it very popular. As mentioned, you only need to rely on your own swimming prowess. You won’t need to pay for any expensive special breathing equipment.

So if you plan to stay at greater depths for a longer period of time, you can take some scuba diving lessons. Scuba diving is mostly beneficial for those who wish to study and collect date on marine environments.

Skin diving is mostly used for food gathering underwater. In some parts of the Caribbean, it is illegal to catch lobsters using any scuba equipment, thus, those who are good in skin make hundreds of dives each day to collect lobsters.

Diving In A Different Environment

More and more are drawn into the beauty of the underwater environment, especially now that humans can go to a hundred feet below the surface with the help of scuba diving gears. If you’re seeking for an ultimate adventure in the depths of the ocean, then scuba diving may be your ticket.

However, before you excitedly dip yourself in, bear in mind that scuba diving poses some hazards to humans. The most common of these are pressure related injuries, such as decompression sickness or air embolism. To avoid these injuries, you must be able to calculate how long you can safely stay underwater. You would also need to know the proper descent and ascent rates, or else, you might find yourself fatally inflicted with these pressure related illnesses.

Most aquatic animals don’t pose any risks to divers. In fact, a diver may be a threat to them. For example, coral could be killed by just one touch.

However, there are also a few marine life forms that may injure a diver. The most common include jellyfishes, stinging corals, fire corals, and sea urchins. Sharks and poisonous sea animals can also injure divers, but very rarely. Generally, animals attack humans only when they are provoked.

Although, there have been recorded unprovoked shark attacks, the number is still few. Statistics even show that your odds of being attacked by one of these dangerous aquatic animals is 1 in 12 million. You’re more likely to be attacked by a dog or a snake when you’re above water.

Scuba diving, being a visual underwater experience, doesn’t include altering the underwater habitat. Divers shouldn’t touch anything, be it a plant, animal or an object underwater.

Usually, the best scuba diving locations are where there are plentiful marine life. Of course, it is an added advantage for divers if the water is clear and the temperature are warm. That would make them see the aquatic beauty clearly and better adjust to the underwater temperature.

The most popular diving destination is the Caribbean. The Caribbean seas house color coral reefs that abounds with marine life. Different types of fishes find shelter among these coral reefs. Most parts of the Caribbean region have been designated to be marine sanctuaries or part, thus fishing and other human activities which could damage the marine life are prohibited.

Ship wreck sites are also being sought to be preserved. Aside from providing valuable treasure and clues to our rich history, these sunken ships also provide aquatic animals an ideal nesting or breeding area. So these ships not only add beauty to the ocean floors, they also have some utilitarian purposes for aquatic animals who live in deep places where resources are very scarce.

It’s been said that there are about 75 000 sunken ships in the North America area alone. These locations also attracted thousands of divers from around the world. Some hoped to find buried treasures while others seek fame for having discovered some important historical links. Still, several dive for recreation purposes just to enjoy what the underwater environment has to offer.

Other protected areas and are also famous dive destinations are the South Pacific, Indian Ocean and the Red Sea. The government and environment organizations try to conserve the beauty of the habitat of these aquatic animals and plants. Although these destinations are open for viewing and recreational diving, enough marine police are assigned to ensure that the divers abide by the conservation rules and regulations.

It is just appropriate to raise these marine conservation issues, especially now that our technology has advanced so much. Technology advancements could also mean a lesser concern for the environment. Just take a look at what’s above sea level. There are several high rise buildings and large factories that contribute to pollution.

Currently, mankind is slowly able to invade the depths of the ocean, too. In fact, submersibles, such as submarines have been invented to allow humans to go into the deepest parts of the oceans. Marine biologists, geologists, archaeologists and scientists are using such technology to enable them to stay in the ocean for long periods of time so they can learn more in their fields of study.

Who knows what the near future has in store for deep water exploration?

Safety in Scuba Diving

Scuba diving is a unique and beautiful experience that everyone should try at least once in their lifetime. Barring perhaps hydrophobics, almost anyone will find the experience of being underwater and floating along both exhilarating and relaxing at the same time. However, without proper training and preparation, scuba can also be a dangerous undertaking, with hazards that can affect the unprepared. With proper equipment and precautions, however, it is a safe and wonderful thing to do. Here are a few safety tips for the beginning scuba diver to consider before taking up diving in earnest.

Training - Get certified. Take a training course that has official certification. If diving only for sport while on vacation like some people do, make sure that you have a certified instructor accompanying you on your dive. If diving in earnest, take a course that will actually give you a certificate for diving (not necessarily as an instructor, but one that will register you as a certified and capable scuba diver).

Physical Conditioning - see a doctor before taking up scuba. Make sure that your doctor gives you a clean bill of health for the physical exertions required in scuba. While mentally relaxing, scuba diving involves enough physical effort that people with weak cardiovascular and especially respiratory systems can’t indulge in it. Asthma, a weak heart, tendencies for asphyxiation, all of these can disqualify a person from scuba diving. Also on the note of physical capability, knowing how to swim is a huge bonus. While not a necessity because scuba gear allows even those who don’t know how to swim to navigate underwater, it is nonetheless a very good thing to know. After all, you’ll be underwater…

Avoid Places Where Bad Things Dwell - your training and certification in scuba will include a ranking that determines what levels of underwater hazards you’re trained to tackle. Avoid any places that you aren’t certified to handle. These areas will usually be very dangerous for the untrained, and will usually include special hazards that need their own branch of specialized scuba training or certain pieces of equipment to overcome. Examples include scuba diving in shark infested waters, ice floes, amongst coral reefs with toxic or aggressive underwater lifeforms, underwater caves, and shipwrecks.

Proper Equipment Is A Must - your training and certification should also include care and maintenance of the scuba equipment. If you’re using your own equipment, make sure that you take excellent care of it, keeping it in top condition. No matter how skilled you are at navigating underwater, man is NOT biologically aquatic, and your equipment is all that’s keeping you alive down there. If renting equipment, give it much more than a cursory once-over. Examine it carefully to make sure there are no flaws in the gear that might cause it to fail during a dive. One of the hazards of scuba diving is drowning if your breathing apparatus gives out.

Don’t Dive Alone - Always have a dive buddy or an instructor with you, as long as you are with someone who has more experience than you. If you’re diving with a buddy, don’t bring along someone who’s also a noobie if you yourself are new to the game. If you’re an old hand diving with a noobie, make sure that your partner knows how to follow your instructions once underwater. If you MUST dive alone, then at least have someone manning the boat on the surface to make sure you’ve got a buddy on overwatch.

Study Conditions Before The Dive - listen to weather reports before the dive to make sure you don’t wind up diving during a typhoon or worse, a thunderstorm. Even if the conditions seem okay for diving, make sure to pack enough medical equipment to compensate for sudden changes in the weather. Even if it’s a heat wave and not something related to wind and rain, adverse weather can be problematic. Heat waves have been known to cause heat stroke and dehydration to divers who thought they were safe from the heatwave because they were underwater. Remember that water conducts heat more efficiently than air.

Know When Bad Things Are Happening - learn and internalize the medical signs and symptoms of the following conditions, as they are the maladies that usually afflict divers. Hypothermia, dehydration, heat exhaustion, and asphyxiation are the things to watch out for, as well as a diver-specific malady called decompression sickness, which occurs when a diver’s body is submitted to and becomes accustomed to high pressures underwater, as well as having air bubbles form in the body from prolonged breathing of high pressure gas. Returning to the surface where the body no longer is subject to these pressures can lead to dizziness, sickness, and vomiting from system shock. It is in a way, comparable to a person being used to the thin air of mountain climbing, when the climber goes back to a normal atmosphere and breathes a higher concentration of oxygen.

Preparing For A Dive - Things to Do Before You Scuba

Scuba diving is a sport that many people indulge in, and it is a fun experience for almost anyone, except perhaps those who can’t swim and are terrified of water. It isn’t without it’s risks, however, and like any outdoor hobby or sport, injuries can be sustained, sometimes even fatal ones, by undertrained or poorly equipped divers. For the noobies out there, here are a few preparatory steps that you must take and some information you need to make sure that you can enjoy your first dive in safety.

Certification and Training - take up a course that actually gives you certification to scuba dive. If you’re just doing scuba for kicks however, like maybe just renting gear out at a beach resort while on vacation, then make sure you are accompanied by one a professional instructor when you do your dive. Also, keep in mind that scuba divers must have skills in swimming and snorkelling as prerequisites for scuba diving. If you’re not proficient in both of these areas, it’s best to try them out first before doing something as serious and complex as scuba.

Equipment Checks - make sure that your equipment is in proper working order. As stated earlier, get proper training before doing a dive. Part of any good scuba instructional course includes the care and maintenance of equipment, as well as spotting potential weaknesses in equipment that can lead to it’s failure underwater. Many divers have suffered accidents during dives due to faulty air lines, but aside from that be sure to check the rest of your equipment just as thoroughly, down to your compass and first aid kit.

First Aid - you’ll need special training in treating underwater injuries, as well as the ability to recognize the signs and symptoms of common maladies incurred by divers, which include hypothermia, decompression sickness, and in hot weather, heat stoke and dehydration. Make sure your first aid kit is well stocked before the dive.

Know Ascents and Descents - part of diving successfully is to keep a pressure gauge and depth gauge that monitors water pressure around you and the depth you’re at. Water pressure increases drastically the deeper you go, and divers can sometimes suffer dizziness, shortness of breath, nausea, and muscle cramps from descending too quickly. On the opposite note, even with a good, controlled descent, a rapid ascent can also lead to system shock and trauma if the diver just suddenly dumps his diving weights and rockets to the surface. The body won’t be able to adjust to the sudden lack of pressure, especially once the diver leaves the water.

Buddy Diving - never dive alone if you’re a noobie. Always have a more experienced and trained diver with you. Keep your buddy in sight at all times, and be sure to follow his or her lead once the dive begins. Do NOT go off on your own, no matter how safe the surrounding waters seem to you. Tempting as it may sound for the adventurous, even if you and a friend take the same scuba course at the same time, remember that he or she does NOT count as a diving buddy if you’re both noobies. There’s nothing more dangerous in any outdoor exploratory sport than a pair of people blundering around in a dangerous environment.

Communication - learn the hand signals used underwater by divers to communicate. Even with a high tech open face scuba mask that has an integral comm radio, these hand signals are a must for any diver. For one, your radio may break down and run out of batteries. For another, you might run into a cute girl on your dive who’s not wearing a comm system…

Navigation - know how to navigate underwater. The training course that you take should include the recognition and use of simple tools like an underwater compass, as well as more advanced things like using underwater floater buoys and line markers that will allow you to backtrack to your starting point once you’re done with your dive. Losing sight of your buddy and getting lost underwater is scary, take my word for it, and having the capability to backtrack and meet up at a predetermined rendezvous point takes a load off your mind if this happens.

Stuff You Need For Diving

Diving equipment is more complex than some people think. For the most part, people think if you’ve got an adequate air supply and flippers on your feet, you’re set for diving. Wrong. I suppose this approach would work for the casual scuba enthusiast, but there’s a lot more equipment needed for a proper dive than a tank and flippers. If you’re going to get serious about diving, here are all the pieces of equipment you’ll be needing, and why.

Tank or Rebreather - this is, obviously, the single most important piece of gear you’ll be needing on a dive. A tank provides you with a good supply of compressed air so you can breathe. Unless you suddenly evolve gills, you’ll need a good air supply for scuba. Rebreathers are small electronic devices that are more expensive then tanks, but they have the advantage of lightness and compactness over a regular tank. Rebreathers actually recycle the air used by a diver, reintroducing oxygen into it.

Masks - there are several different types of masks, and you can pretty much pick and choose from which type you want. Goggles are the smallest and simplest mask type to use, while others have integral snorkels for breathing in shallow water. Aside from these simple eyegear affairs, there are also full face masks with integral communication gear that allows you to talk to other people while diving via a built in radio comm unit. These are the preferred types of masks to use for deep extended dives, as some models of full face masks also include low light vision lenses, and these are essential for traversing depths which aren’t penetrated by sunlight.

Thermal Suit - diving gets COLD. A full body suit is necessary for serious diving endeavours. These rubberized suits are full body wrapping outfits that not only help with thermal insulation, they also help to avoid abrasions if the diver’s skin encounters rough surfaces, especially coral. Getting mugged by a jellyfish is also not a pleasant experience if all you’re wearing underwater is your skin. Another note, the pressure applied by a wetsuit can also prevent bleeding from small wounds incurred underwater. This is essential for those who like swimming where sharks hang out, unless you enjoy being a snack for Jaws and his buddies.

Weighted Plates - contrary to the popular belief of those people who can’t swim, people do NOT sink like rocks when thrown into the water. The human body is naturally buoyant, and will float in water, especially salt water. To this end, divers need to carry different sorts of weights to adjust their depth when they’re diving.

Fins and Diving Motors - for propulsion underwater, you’ll need either fins or, for those who want to conserve their energy, you can buy a Diver Propulsion Device, which is an electric motor driven device that you hold onto. It is roughly the size of a large vacuum cleaner, and basically does the swimming for you.

Gauges - you’ll need a compass for navigation underwater, along with underwater pressure gauges and an electronic depth measurer to make sure you don’t go too deep and encounter pressures that may cause you decompression sickness.

Dive Markers - these are floating buoys that you need to set to let people on the surface know where you’re diving. This is essential for safety in case you run into problems underwater, as well as providing a means for passing boats to know there’s a diver in the area, which lessens the chances of bonking your head on a passing ship’s hull when you surface.

Handheld sonar and Light - for navigation in extremely dark areas, as well as for diving at depths where sunlight from the surface no longer penetrates, having an underwater sonar and a portable electric light source is a must.

Underwater Buoys and Line Markers - aside from surface buoys for marking where you are for passing ships and boats, underwater dive buoys also help you to navigate underwater, marking territories which you may want to come back to later so you don’t get lost, as well as letting other divers in the vicinity know that you’re around.

First Aid Kit - diving equipment shops will offer specialized first aid kits for treating injuries that may happen underwater. Having this kit with you is a must, as well as taking lessons in their use.

Miscellaneous Tools - having a knife, waterproof camera, lines of wire with electronic reels, a dry box for your wallet, phone, etc, and a gunny sack for holding things you nab from underwater is also something to remember. These little knick knacks aren’t really necessary for a successful dive, but they come in handy.

Scuba Diving Career: When You Want It To Be More Than Just A Hobby

Are you tried of your normal workday? It probably seems that there’s nothing more to life than driving to work in the morning, working with uncooperative colleagues, getting very tired, and then drive back home. Add to that all the noise and air pollution you encounter along the way.

If you’re adventurous and unconventional enough, a career in scuba diving may be right for you. Usually, those who pursue scuba diving careers were scuba diving enthusiasts who wish to take their hobby a little further. Scuba diving couldn’t possibly be compared to other career choices.

Instead of causing stress, it is a rejuvenating activity. You get paid by doing something you like. You get to impart your knowledge on the sport with other people who share your interest. In scuba diving, there’s no unappreciative boss and annoying colleagues.

Starting a scuba diving is a bit like other careers, though. You should have that extreme interest in diving, and then develop your abilities to working on that. Though it seems so easy since scuba diving sounds all about fun, there’s more to learn to become a scuba diving instructor. You would have to master not only the craft of teaching but also develop an expertise in diving.

Like other professionals, scuba diving instructors also used to be students. They began with easier courses on scuba diving and then slowly moved on to more advanced courses. Of course, through the process, they were able to see more to scuba diving than just having fun while diving. They were able to see a different side of scuba diving that encourages them to share the sport to others.

If you ask any scuba diver instructor, he’ll probably tell you so much about what scuba diving has to offer. For the love of the sport and the desire to let others experience the beauty of scuba diving, they ended up being a scuba diver instructor.

Although you might think that scuba diver instructors know everything there is to learn, the truth is there is still so much to learn about scuba diving. Scuba diving is an evolving activity. it is used by the military and scientists as well. Nobody can possibly learn everything about scuba diving.

That’s why more and more people are getting interested in scuba diving. It offers a whole new world and constantly opens more doors to exploring the mysteries of the underwater life. If you are up to this challenge, then you should seriously consider a career in scuba diving.

To be a scuba diving instructor, you would first need to be a dive master. There are a lot of several scuba diving schools or agencies where you could get a certification of being a dive master.

By the end of an instructor development course, you are expected to learn more than just the basics of diving. You’ll be taught about diving standards, safety and regulations and the scuba diving system as it relates to the law. Of course, you’ll learn several techniques that you can employ to effectively teach your future students.

This extensive course will definitely make you master of scuba diving. You’ll learn everything you need to know to kick start your career in scuba diving. Of course, the rest of the learning process will follow once you have started your craft. Like many other careers, you only get about 20% of the knowledge from training, and you derive the rest in the real world.

As a scuba diving instructor, scuba divers could expect a lot from you. You need to be able to teach scuba divers how to safely scuba dive and at the same time have fun. That is quite a responsibility. Your students have placed their life’s security on your hands, but that doesn’t mean it’ll be easy to teach them how to stay safe and remain alive while underwater.

There are also other things you have to look into in pursuing a career as a scuba diver instructor. Like other careers, there’s much marketing involved. You may have to learn a little on sales literature and product marketing. You don’t have to buy everything they advertise but you need to understand the scuba diving business industry. The market in scuba diving largely affects your job and your students as well.

Training Courses and Prerequisites for Scuba Divers

Scuba Diving is a sport that has grown in popularity in the past decade, evolving from something that was utilized by scientists and naturalists to further their research, turning into a popular pastime for many people. It’s grown to such an extent that even beach resorts have started offering scuba diving lessons, as well as equipment rentals and certified trainers to accompany untrained noobie divers who just want to try it out.

Scuba means Self-Contained Underwater Breathing Apparatus, and involves operating underwater with a tank or rebreather that supplies oxygen to the diver. Types of Scuba are seperated based on the breathing apparatus employed in the dive. In open circuit scuba, the air is supplied by a tank or other source, and once inhaled, is exhaled into the surrounding water. It is the most common type of scuba used for recreation.

In closed circuit scuba, the air is recycled though the use of devices called rebreathers, and oxygen is reintroduced into the air supply of the diver by an apparatus. In semi closed circuit scuba, mixed gases are used as the air supply, taking part of the air exhaled by the diver as well as adding to it with an air supply similar to that used in open circuit scuba. Semi closed circuit scuba is more difficult to learn than open or closed circuit scuba diving alone, because it involves knowledge from both types of diving because the breathing apparatus used is a fusion of the two.

Scuba diving clubs and other organizations offer lessons in scuba diving in an effort to expand the growing popularity of this sport. On a more professional level, some of these organizations even offer advanced scuba lessons which allow trained scuba divers to expand their repertoire and go diving in conditions and environments which are otherwise restricted to other divers who don’t possess the training to handle them. Here are some of the prerequisites for diving, as well as some of the advanced scuba courses that experienced divers can take.

Prerequisites - any and every scuba diver must have skills in swimming, obviously. Aside from this, however, a scuba diver must have had training and experience in snorkeling, which forms the basis for some of the techniques used in scuba diving. If you want to take up scuba diving as a sport but don’t know how to snorkel yet, then take up snorkeling first before taking a course in scuba.

Regular Scuba Certification - this trains a person in the basics of scuba diving, allowing operation in shallow water and near shorelines, and is mainly used for training scuba divers who undertake the sport for purely recreational purposes. For a vast majority of people who take up the hobby, this is enough.

Open Water Scuba - this is for scuba divers who operate out of sight of the shoreline. They will have to take a boat to get to the dive area, so skills in operating a boat are part of the prerequisites for open water scuba diving. Open water scuba usually involves diving to greater depths than a regular diver, and divers who use this method need special equipment like floater buoys to let other boats on the surface know that there’s a diver in the spot, as well as underwater line markers, reels, and underwater floaters for underwater navigation.

Rescue Scuba - this is a special training course that focuses on rescue operations for other divers. Those who usually take it are employed in the search-and-rescue business. Training includes first aid, obviously, as well as underwater techniques for getting people out of hazardous situations like underwater caves. There is also training in the use of specialized equipment used in such rescues.

Deep Dive Scuba - this is scuba diving in extreme deep water conditions, and includes training in the use of equipment for operating in high pressure depths. Deep dive scuba is extremely dangerous and not recommended for casual divers who are taking it as a hobby, since in some cases it involves descending to depths that feature water pressures that would physically crush a person wearing regular scuba gear. Naturalists usually take this training up as a way to study sea-bottom dwelling life forms, and geologists and oceanologists likewise take it up for studying underwater formations like volcanoes and rock fissures.

Hazardous Area Scuba - this type of training specializes in teaching scuba divers advanced forms of safety in scuba diving. The diving skills required per se don’t differ too much from the levels of skill involved in regular scuba, but additional training is given for allowing a diver to explore hazardous area that are usually restricted to regular divers. Some examples of hazard areas include shipwrecks, coral reefs infested with toxic life forms, shark infested waters, and underwater caves. While not for the regular hobbyist, some of the more serious scuba divers take this up for thrills.

Instructional Courses - this type of scuba course teaches a scuba diver how to teach other people to scuba dive. It also features training in basic first aid to help injured pupils, as well as tutorials in buddy systems that are required for helping noobies along underwater. Obviously, a certificate in basic entry level scuba diving is a must for taking this course up, though no proficiency in the more advanced courses is required since this mainly focuses on teaching others the methods of recreational scuba, and not professional scuba.

Going Scuba Diving?

Who wouldn’t want to explore the world under the sea? Mankind has always been fascinated with life underwater. Because of this great fascination, extensive researches and amazing inventions have given us the chance to breathe underwater so we can observe or simply have fun in dealing with aquatic animals.

However, breathing underwater isn’t just simply bringing a tank full of air with you when you dive. There are many things that you need to consider. Staying underwater is totally different from living on land.

For one, humans don’t have the gills that can extract oxygen from the water. Air pressure is also significantly different from water pressure. The human body isn’t adapted to high pressure changes. Controlling your buoyancy and avoiding losing body heat when underwater are also major considerations.

Fortunately, probably everything that a scuba diver needs to safely explore the depths of the ocean is available. There’s the mask, snorkel, fins, regulators and diving suits to name just a few. These equipments allow the diver to breathe, control their position and stay warm underwater.

To breathe underwater, a scuba diver wears a metal tank full of compressed air. A regulator is attached to this tank, which adjusts the air pressure to match that of the surroundings so the diver can breathe comfortably. The regulator delivers air through a mouthpiece which the diver uses to inhale and exhale. Breathing through your mouth comes naturally, so you don’t need to add that to your worries.

Another hose is attached to a regulator to control the diver’s buoyancy. It is attached to an air bladder which is adjustable. Since the diver wears this as a vest, adding air into it would make him more buoyant, and thus, he rises. When he releases the air, the opposite happens.

These buoyancy compensators also help a scuba diver achieve neutral buoyancy. When you are in neutral buoyancy, you can stay at a constant depth without much effort. This minimizes gas consumption due to swimming.

Divers also wear lead weights as a belt to allow them to descend and stay underwater. The weights are evenly spaced to achieve proper balance. During emergency situations, a diver can just quickly release these belts to rise to the surface.

A diver’s suit is really incredible. It is made of compressible substance, thus when you descend, it reduces the volume, and when you ascend, it expands. They are very helpful in conveniently controlling one’s buoyancy.

A suit can also provide thermal insulation. A wetsuit, for example, is usually made of neoprene that has poor thermal conductivity, which minimizes body heat loss to the surrounding water.

Another way which a driver’s suit can reduce loss of body heat is by trapping a layer of water between the suit and human skin. The wetsuit is very well sealed at the neck, wrist and legs thus water flow rate is reduced. This technique in reducing heat loss is known as convection, which is the same principle used in the concept of semi-dry.

A drysuit on the other hand keeps the diver dry, as apposed to a wetsuit. Frigid water couldn’t possibly penetrate a drysuit. Preferably, drysuit undergarments are also worn for better insulation. A drysuit keeps thin air layers inside that helps keep a diver warm.

Of course, to be able to familiarize yourself better with these scuba diving gears, it would be best if you get yourself a certification by passing a scuba diving course. In the course, you’ll not only learn about these equipments, you’ll also be taught how to adapt to diving.

During the course, student divers learn how to achieve neutral buoyancy. Through various swimming exercises, they will learn how to control their breathing rate. A diver should know how to breathe in a slow but continuous manner.

At the end of the course, you are expected to know some safety procedures in diving, such as how to clear your mask if in case water leaks in, how to avoid any mishaps while underwater, and of course, learn to help a fellow diver in need. Conventional hand signals are used underwater to communicate since divers don’t have another way to talk to each other.

By being a certified diver, you could refill your air tanks, buy scuba diving gear and scuba dive anywhere in the world. Scuba diving businesses require this certification as proof that you can well manage yourself underwater.
