The chance that you start the skin diving is painful ..the desire.. , saying that "I want to swim with the dolphin" possibly.
It might be one of the ultimate shape of the skin diving that swims certainly with the dolphin.
However, the charm of the skin diving is not only that.
For instance..knee..soaked..place..rock..beach..water..hard..see..small..living thing..move..find..flap..disregard..mask..at last..water..soaked..place..shallow..surface of the water..fall..rain..see..dive..seaweeds..hang on..do..existence..as if..disregard..approach..fish..enclose..these kind of things..after all..tank..shoulder..taste..thing..think.No do be known whether a free point like Okka is a charm no matter such what is done with the lightness of the body either.
Is does it pass for the first time for a long time, and being possible to keep still diving the favor as for skin?
It would be greatly appreciated if wonderful of the skin diving is told by you even a little by my very few knowledge.
Chapter 1 Preparation chapter
1.About equipment About equipment, it is the one used at the tank, and, of course, there is not a problem either.
The skin diving can be done as long as there is a mask snorkel tube fin to fit.
A coral sea is diving time and is thought by me that you should dive though thinks it is the lightest and is wonderful because diving with the bathing suit can not put weight because it puts on a thin one suit even if it is the lowest when thinking about the medusa measures etc.
We will personally encourage the one of the full foot type only by the fin though there is especially no regulations in each machine parts.
Because scuba diving in me and the ratio of the skin diving are skin divings considerably inclined to compared with the normal person, only the fin is sticking to, and has used fins of a considerable number up to now.
Personally, do you like long, delicate fins?
To the end in the reference because is a problem of the favor.
2.About the weight adjustment There is especially no regulations to how many kilos to adjust weight though needing if it puts on the suit is weight. For instance, "I am few because I am scary when it is too heavy because it is not good at swim" is ants.
When feeling, "The physical condition is bad for a moment today", I also make it to few occasionally.
Above all, defend most is "The plus buoyancy is secured in the surface of the water. "
"It is possible to breathe without becoming vertical in the surface of the water and moving the fin" is a major premise in me.
It is possible to hold the Tsra and it is done that it is necessary to tread water for a long time in the surface of the water.
Weight is NG in impossibility because it puts it to "Enjoy it" straightening after all.
What should be thought is "To m in depth how many is buoyancy 0 taken?" though "Then, make it to kilos how many"
For instance, it is possible to swim in Si in the state of the neutral buoyancy in 8m in depth if weight is additionally put to become buoyancy 0 8m in depth.
It is necessary to decrease 20m in depth in the amount of the same weight and to decrease weight still because the buoyancy decreases fast when 8m is passed when starting diving and it is very dangerous.
It is "Weight is matched to my target depth", ,in a word,, translation.
It is meant to keep the balance of the body when the surface of the water moves and the dive beginning (jackknife), and moreover, weight of the installation of weight is not destroyed the system by putting as much as possible in front of the body and ends. (This is similar at the tank. )
Chapter 2 Basic chapter
1.Snorkel tube clearness There is no change with the one done when the surface of the water moves in the tank about a clear snorkel tube. However, there is a big difference in the importance degree of a clear snorkel tube with skin in the tank. Because it is necessary to clear the snorkel tube whenever it dives after all.
Therefore, it is necessary to acquire it firmly as a basic technology to correspond to all situations as it doesn't make little of a clear snorkel tube.
Underwater substitution method
There is an underwater substitution method as one method of a clear snorkel tube.
This is the one of entering the state that the snorkel tube had already been cleared when water in the snorkel tube is pushed out by putting out the breath little by little with it had the mouth of the snorkel tube for the surface of the water below (In the state to have the mouth up, so that the vomited breath may run away all), and it surfaced in surfacing as for the face. Therefore, after it surfaces, it is possible to inhale at once.
Because the snorkel tube can clear more easily than clear snorkel tubes in surface of the waters at a dash if it is this method, it is a technology that wants to acquire it by all means.
2.Mask clearness It is necessary to do in the limited breath in skin though the mask is clear in the tank ..what.. ..it is possible to do without difficulty... Therefore, I do not think the amount length time for the problem to exist if the water of the mask is turned on after it enjoys the world in water, and it surfaces because it endures it even if a little water enters at no so long time even surfacing. Because necessary oxygen is needed for the vomited breath and the operation to clear the mask.
3.Mask blow It is thought that it is not necessary to consider it so much in skin in shallow depth, and because hydraulic pressure hangs of course when diving in deep depth, the mask blow might be necessary. However, I think that it need not consider it too much because it doesn't think can doing Aza of the mask type by congesting etc. when even surfacing is not so long time in this to be so.
4.Ear pulling out The problem of first facing might be this pulling out of the ear. The person who doesn't come off easily the ear thinks that it has a hard time extra because there is an individual variation in the omission condition of the ear.
First of all, from limbering up before skin is done. The ear is made easy to come off even a little by the massage of the ear back, and opening the mouth greatly and the right and left movement of the jaw.
And, there is nothing except "The ear pulling out is done to earlier than usual" though it is a knack when actually diving.
Hydraulic pressure begins to dive because it hangs and will do the ear pulling out at once of course only to the bend of the upper-body in water when the following jackknives are done.
"It is possible to dive with the person made free" is needed because it is thought that it usually pinches one's nose and the ear will be pulled out though the person who comes off the ear only by swallowing saliva is another.
In a word..person..use..lack..jackknife..do..way..become..thing..smooth..ear..pull out.
And, it can easily enjoy the world in water of long time by pulling out the ear by necessary minimum labor while going underwater.
5.Fin kick A detailed explanation omits, and describes the method of two kicks roughly divided because it thinks the fin kick to be changeable by the fin used also how to scratch.
Flutter kick
The flutter kick is so-called "Butter reed", the fin kick that you are always using, and there is no change with the one done in the tank. The kick in the back of the body cannot be used because the back of the body is in the water as well as the movement in the surface of the water with the tank. The fin kick of a long stroke in front of the body is needed. If it wants to kick the fin more easily, side or the back (Advance toward the back) is ..body.. effective.
Dolphin kick
It is well-known dolphin's fin kick. To make the wave, it kicks by the entire body as an image like the break-dance of ..longing.. in old times. Seeing the image etc. of the good person (Mr. Otari) and remembering might be the best shortcuts to remember this.
It is personally felt, "Using the entire body is and there is a torque (advanced power)" and "Using only the foot advances fast" though "Using the entire body advances early" or "Using only the foot advances fast" is various depending on the person. Moreover, it personally thinks of an advanced easiness like this and good kick in case of not being though it tends to be seemed, "The Dolphin kick is tired". (The flow is used also in the tank. )
6.Breath method Perhaps, I think that "Hyper ventilation" was learnt at you and an open water courses. This is the one "The sense felt suffocating is paralyzed it" repeatedly of "Early, deep breath". (A lot of oxygens are not taken into the body never. )At the same time, I think that "Blackout" was learnt. The change into "The sense felt suffocating is paralyzed it" straightening and the body might come rapidly, and it become a faint. Therefore, "Hyper ventilation" is not honestly encouraged. After "Hyper ventilation" is done and it dives, it takes time to recover that much.
Hurried time comes to be able to dive if about 2?3 times breathe deeply if it is a range "Dive happily". Will be able it to relax at the same time as breathing deeply deeply and deeply, to go underwater smoothly, to pull out the ear smoothly, and, if possible, to dive place length for which it surprises it even by me.
The practice method is taught for the person who aims in addition.
Still, "Hyper ventilation" not encouraged at the enjoyed level is needed if diving more than a certain level. However, it takes time to recover more as previously stated. Therefore, when "Breath" is forged, it is necessary to forge "Recovery power" at the same time. Because "Daraa" must float for a while after it dives. (← Kiken)
It is the most effective to do the number of sets repeating "Breath during the fixed time" and "Take a rest during the fixed time" to forge "Breath" and "Recovery power" at the same time. That is that and an assurance of the forge if both "Fixed time" and "Number of sets" to say nothing of the beginning are set few, and it increases it little by little.
It is . in taking a streetcar though this is a practice method that had been done well in old times as for "One station section breath" and "Take a rest between districts one station". However, because it is an assurance of gone of "Haahaa" and the person to ..breath.. end from "It is Coits in what" and surroundings when making it to painful, "It is recovered without having a very painful face" is misoes. Please choose the route because it is that world taking when it does in the route with the section of one station unabashedly for ten minutes like Toukaido Line.

Chapter 3 Basic chapter A basic technology when actually diving is described.
1.Relaxation first of all Well, at skin (The tank is also similar) though it begins to dive more and more, importance first of all is "How do you relax?""Relaxation" mentioned here is that relaxing the body is nature, and relaxes in the head.
It is a brain that consumes the most a lot of oxygens in the body though thought that it knows you. It is thought, "It is scary", and is consumed oxygen more only by thinking about the thing.
How do you relax?So-called "Combine with the sea" As the image, is it a sense?
It is in mental Ne with a flexible, strong body making and the considered breath method though there seem to be a lot of people who are doing "Yoga" to Fredaibar.
Is so-called "Stage of the selflessness" a guy?
Is Zen meditation also good?
However, do not make the tension "0" (0) because it relaxes.
Because danger must be attended to leisure to take notice of nature such as mountains and seas compared with other leisure.
I think, it should be "It keeps always having fear to the sea" though this is an opinion.
2.Surface diving "Surface diving" is up to the one like the jackknife that dives shallowly though it is a word that cannot hear too much and become it. It is an image in "Surface diving" that dives under the diagonal while the jackknife dives in the right under. It is the one of sinking the upper-body forward under the diagonal, and sinking the lower half of the body according to the upper-body by feeling that kicks Dolphin.
It is possible to dive by remembering this even in a shallow point where the head attaches in the jackknife, and wanting to move early dive in the place of about 1m under the surface of the water for the surface diving and move straight for the Dolphin kick in water.
3.Jackknife "Relax", "Set targets", "It turns aiming at the upper-body and bend it", "The lower half of the body is set up and become vertical", and "Thus when the fin sinks. "
However, it is "Do not dive by power. " at all to want you to note it here. It is essential that it is not so and "Ease", "It is quiet", and here sink by "Weight" "Merge in the sea" in the image, too though the spectacle to which "Gabaa" begins to dive mightily is seen from Pcaa and the floating state in the surface of the water often.
Moreover, it is a useless struggle naturally though the fin is seen to be done noisily in the surface of the water well. It is not because of sinking even if how much the fin ..in the air.. and it exists. (It is clumsy. )If possible, you must feel it by the sense though you may look whether it sank the fin ahead. 2?3m is sure to sink even if the fin is not lacked if propriety can do weight and an adequate jackknife.
Only the jackknife is repeated well without using the fin to confirm the jackknife. (If they are two ?3m in depth, it should be able to reach bottom of the sea at last. )
Moreover, let's try from the state of the movement in the surface of the water as it is as the next stage when becoming it to do the jackknife with the state that floats quietly.
Chapter 4 Chapter of practice Practicing more technology is described.
1.High-speed movement For instance, it is assumed that it wants to move to a certain place early. It is possible to move at high speed by combining the surface diving and the Dolphin kick to move earlier though you may move the surface of the water of course.
First of all, it swims in the surface of the water while slowly straightening breath, and the target thing in water such as the rocks is decided in a direction that wants to be advanced of me. It breathes deeply, the body dives, and the surface dives in the blur toward the target thing. And, it is the one of facing the target thing by the Dolphin kick as for shallow depth.
It remembers and I do not think that there is a disadvantage because it can use this by all scenes.
2.The back Dolphin Dolphin is flapping kicked though it is a method of practicing the Dolphin kick done well recently with becoming Mu disregarding.
First of all, breath is slowly straightened with becoming disregarding of ..flap.. Mu. It breathes deeply, the body is averted, and the upper-body is sunk in water (image like the start of the backstroke). And, the Dolphin kick begins, and shallow depth (About 50cm) kicks Dolphin in parallel to the surface of the water while seeing the surface of the water.
This becomes a practice to kick Dolphin in parallel straight with the practice of the Dolphin kick (advanced practice toward the direction of which it thought because of the Dolphin kick). If it is practiced to avert the body from the state to kick Dolphin in parallel to the surface of the water aiming at the bottom of the water, and to go underwater for feeling like a reverse-jackknife when becoming accustomed to this as the next stage, it must be useful by Dolfinsim. (Dolphin kick of looking up at dolphin)
3.Somersault It is an operative technology in the dolphin as said, "Somersault if it is called Dolfinsim". As attention, let's become careless the fin kick, hang by the foot, and practice to turn in a moderate speed and a moderate size if starting turning too much small.
When it is practiced to turn to length, some depth is necessary. To turn horizontally when practicing by shallow depth, it practices.
4.Simulation It is a practice whether it is possible to swim by becoming a couple of two people, dividing into the dolphin post and the swim person, and matching the breath very. The person of the dolphin post swims freely, and swim person's person : in the one of swimming according to the movement of the person of the dolphin post with opposite.
Let's go to the sea. And, let's receive today with a smile with manners. And, let' s finish.
We wish to express our gratitude to ourselves of today. And, we wish to express our gratitude of surroundings to everyone.
