Master your skill of buoyancy

Human knows little about his body capacity, that is why he cannot hold his breath long under the water and rationally control his body movements. Would you like to learn to swim like a fish in the sea? Diving – is the best way to do it. To feel the level of proficiency it is enough to plunge down deep, where every move requires lots of effort without the skill.

Graceful moving in unison with the sea depth inhabitants singles out a person, who has mastered his skill of buoyancy. Many tourists thing that, paddling with fins vigorously is an effective way to spend energy, but it is a false belief. People, who learned to control their body and increase buoyancy make almost no use of the equipment at the time of moving under water. They are able to keep their body on the same depth within 10 centimeters. What is more, a huge part of buoyancy is the ability to control breathing. Poeple, who are professional divers, spend the air much more rationally as opposed to beginners. Remember that all this comes with practice and the only thing you need is desire.

Some tourists purchase diving tours especially to the Red sea. Regular dives reveal new beauties of the underwater flora and fauna. A large number of trips to the sea bottom does not indicate high skill of buoyancy. Only after finishing diving lessons with an instructor can one master this skill. According to the results of the training a diving school gives their student a certificate. The use of the received skills and knowledge not only gives a person maximum pleasure from diving, but also make a contribution to the environment. Professionals of their craft are able to move along the bottom not damaging the environment which is very important.

Specialist of this field advise the beginners to primarily learn buoyancy and go through a corresponding course. Only after mastering the required skills can beginners get real pleasure from scuba diving. Diving for children finds his true admirers of 12 years old. It is worth noting that learning at an early age is much faster and easier.

Where are these trainings take place and is it possible to learn buoyancy? Diving training takes little time, that's why you can spend a holiday by the Red sea in Israel with to your advantage. In Eilat on the shore the Gulf of Aqaba water temperature has the most comfortable figures for diving courses: from +21 to +29 degress C.

Diver’s note: to drink or not to drink?

People see drinking alcohol as an ancient national tradition. Can you still follow it when you dive 30 meters deep and even deeper?  This very question causes much controversy among those who are really keen on diving.

Is it possible to combine diving and alcohol without any risk of damaging health? The answer seems obvious. What is more, recommendation to restrain from alcohol before and after diving was not just made up. Alcohol is forbidden by the PADI standards.

Does the amount of alcohol matter at the time of diving? It definitely does. When a person drinks a bottle of vodka, he loses his coordination and ability to think rationally on dry land to say nothing of the depths of the Red sea. The situation with such high dose is quite clear.

What if we consider just a can of beer or a shot of vodka? Such a dose does not cloud reason, the reaction remains adequate, a person is still able to put on the equipment and pay attention to what instructor says. Everything seems normal but unfortunately it is so only on the outside. The body is already experiencing an insignificant degree of dehydration. This very physiological state is very dangerous for a diver. One of the dangers is decompression sickness that is familiar to many diving beginners. To be safe one needs to pay close attention to his or her health and listen to the advice and directions of instructors at the time of diving training.

It is no coincidence that a person feels harrowing thirst during a hang-over, because any kind of alcohol dehydrates the body. When it happens of dry land, it is noting critical. When it happens under water different rules apply. A dehydrated body under water has a strong chance of developing a decompression sickness.

Experienced diving instructors always recommend drinking a lot of liquids at the time of training. Water thins the blood and provides its normal circulation. Intensive drinking regimen – is a golden rule of a safe diver. It needs to be mentioned that for a person who drank alcohol recently or in the very day of diving this is less effective. The risk of having a decompression sickness after drinking alcohol for a diver increases drastically, even if all the safety norms and surfacing rules are precisely observed.

One more question that is really important to divers is whether it is acceptable to drink alcohol after diving and if so, how much is allowed? You shouldn’t grab a beer to celebrate a successful dive having just stepped out of the water. At that moment the process of retaining B.U.N from the body is not yet finished. That is why any factors that cause blood thickening (alcohol) may provoke decompression sickness. If it is impossible to completely avoid having a drink at the day of diving than is should be put off. The first safe drink of alcohol a diver can have only 4-5 hours after the surfacing.

In case of a technical problem act according to the instruction!

Diving is one of the safest kinds of active rest if you follow the diving rules and make a timely maintenance of your diving equipment. However it is impossible to completely exclude the possibility of a technical faulty that is why a diver has to know how to act in case of emergency under water.

Failure of second stage of regulator being under water

Respiratory system of a person operates only when the pressure of the air delivered to the lungs is equal to the external pressure on the body. The difference between these pressures cannot be more than 14%. Second stage of regulator provides this equality when the air is supplied. In case of its failure you need to come to the surface using an alternative air source. Usually it is an octopus of a partner’s scuba. It is an additional second stage with a long hose. In case of emergency both divers can breathe in turn using one scuba on their way to the surface.

A breakdown of a regulator may occur due to its blow on underwater rocks. In such situations a diver has to be ready to solve the problem.

A jammed inlet valve of a buoyancy compensator

To try and unblock the inlet valve BCD, you should unplug and plug back in the feeding hose. If all the attempts of restoring the functionality of the valve that provides the air supply from the regulator are unsuccessful then a compensator can be inflated through mouth. Former generations of buoyancy compensator were design for this kind of usage.

Detached connecting pipe of a feeding hose from an inlet compensator valve

In such case connection of the details has to be restored. Sometimes in such case the valve is jammed in an open state, which is indicated by the sound of air leaking in the water. That is why it is important to stop the air feeding from the cylinder with the help of a stop-valve. Then you need to try and restore the functionality of the valve, attach the connecting pipe and open the air feeding.

The difficulty of the operation is connected to the uncomfortable location of the stop-valve behind the diver’s back. Only some divers with long arms and good mobility of joints can reach it. Diving partner can help block the stop-valve. If it needs to be done singlehandedly then you should loosen the waist strap and move the cylinders closer to the head. Not to face such problems some divers prefer to install them behind the back stop-valve facing down.

Dislocation of cylinders

Most divers attach their cylinders to the compensator using plastic clinches. If you haven’t checked the safety of the attachment then it may be loose and a cylinder may slip out. To try and put it in the right place you will have to take off the compensator. It is much more convenient to use the help of a partner. Holding the cylinder with his knees he will be able to fasten it tightly in the clinch using hands.

Being under water, pay close attention to your partner and follow instructions.

Reliable mask – a key to incredible impressions!

Diving can be compared to a journey to a different universe, created by a talented science-fiction novelist. Sharp coral reefs, fantastic inhabitants of the underwater world, unusual plants and deep caves that keep secrets of the sea bottom and lots of other details give amazing emotions that will stay with you for a long time! No wonder that diving training has become one of the most demanded services – every person wants to plunge into this other universe, a feeling that is comparable with a flight in space.

How to choose a mask for underwater exploration?

Diver’s way is thorny and dangerous, but very interesting! Danger awaits the brave adventurer on every corner of his challenging path, but these are not monsters or predators that inhabit the deep caves. The main threat is in careless preparation before diving. The most common problem of all beginners is a leaking mask. When the “skirt” sealed to the frame does not match the face of the diver, the mask starts leaking. Experienced divers say that faces leak and not masks, but despite the harsh professional humour, the problem is still quite relevant.

Entering an equipment store beginners are lost because of the wide selection. The “skirts” of the masks used to be made of rubber. Due to the features of this material the number of colors was limited to black and green. Technological advance has brought divers silicone that became a new step to a more comfortable diving. This material is long-lasting and doesn’t irritate skin as much as rubber does. Composite materials are more complex – their characteristics depend on the initial components.

We recommend using equipment of famous brands. Large manufacturers live up to their reputation and try to provide a customer with a quality product according to the price. Cheap equivalents of Thai handymen are no match to masks of European producers. Cheap masks are less reliable.

Checking how well a mask fits the face is quite difficult in regular conditions. Most beginners learn about the leaking only after the immersion. Pressing the mask against the face and breathing in is useless – you will feel that the “skirt” is tightly adhere to the face, but at the time of diving the water will still penetrate through small holes.

Mask adjusting should be done in the water. We recommend you to check how easy it will be for you to block the nostrils in a thick glove. If you find it difficult during a check then during equalizing you will surely experience problems. Check if you can adjust the mask strap with one hand. At the time of our underwater journey your other hand may hold a video camera, a torch or a photo camera – then you will have to adjust the strap with one hand.

The lighter the mask the tighter it stays in the place. The number of lenses doesn’t really matter. The most popular are twin lens masks – they are comfortable and very clear. Additional lenses at the sides provide a fuller visibility and simplify reading of the devices such as pressure gauge. Men should choose the mask even more carefully if they don’t want to lose their facial hair before going to the dive-center. Some masks, that provide total tightness, may leak because of a mustache or a beard. A good diving mask is a key to the fullness of emotions from a fascinating journey in the underwater world.
