ZERO TO HERO: FROM THE EYES OF A FORMER ZERO

Not all heroes wear capes, some wear wetsuits

By Akshay Thatte

(These are my thoughts on having completed the Zero To Hero course two months ago. I feel it would be good to share my thoughts and experiences a few months after having finished it, just to ensure that there is no bias or hangover of the course persisting. A lot of things are said in jest and must not be taken seriously. Any hurt caused is deeply regretted. Do not come after me. Please 😊)

The Freediving Program From Zero to Hero is a long-term course that allows anyone with no prior freediving experience to progress and make it all the way to an Instructor. You can go from being the Jon Snow of freediving and transform into a Freediver; A rare breed of neoprene-wearing human, that’s found in mostly tropical waters. You can hear their distinctive calls of Frenzel and Mouthfill from conversations in bars that distinguish them from their bulkier cousins; the scuba divers. With the amount of sign language involved, add the right soundtrack and they could well be rappers in another dimension. But you are here to be a freediver, a Master Freediver who goes deeper than your imagination has fathomed so far. 32 meters is 104 feet or a ten-story building. That’s a lot of distance to cover in one breath.

Inhale. Let’s go.

Why/Who Should Do It

Who should do it? Pretty much anyone who likes the sea, and marine life and or is looking for a new extreme sport that isn’t life-threatening on a daily basis (like cliff jumping). If there’s a longing desire to spend more time in the sea watching all the fishes there are to see, but the inevitable time limit of scuba or just the distance to the fishies while snorkelling bothers you, then freediving is the way to go. No disrespect to scuba, but that 150 bar in the tank disappears faster than /savings in a casino/politicians after election results are announced. Take your pick.

The comfort with your body, the sea and the confidence to duck dive anywhere is a priceless skill. Yes, it’s a callback to that old Mastercard ad. Speaking of Mastercard, this is also the most financially viable course to learn in terms of training dives and time.

If you already have done some form of apnea, spearfishing or just dabbled around then this is the most organised, structured option there is. The Freediving program Zero To Hero is meant to progress beyond the advanced course systematically, learning new techniques that form the foundation of any freediver. Beyond 20 meters is when time, technique and guidance become crucial. Which brings us to the next point.

THE INSTRUCTOR

How do you choose where to do it? The answer is simple, find the best instructor. Your instructor is everything in the course. Fins, wetsuits, nose clips, and all the sufi gear you can get your hands on means nothing without the Guru. I have been blessed to have been taught by Sergei, who’s not just been teaching since PADI began its Freediver courses 10 years ago but has also trained more instructors than one can count.

But just these credentials are not what makes him stand apart, it’s this smiling Buddha- Zen-like energy that makes the difference. I have yet to see him even display mild annoyance. Considering there were 5 Masters students in varying stages of the course, I am sure it would have driven him up the wall at times. But hey, that’s why he is the boss. My first instructor, Shonali Ghoshal, herself an accomplished Scuba Master Instructor graduated from the same school of thought and institute- Kaizen Freediving in Koh Tao, Thailand. A testament to the quality of instructors produced.

Calm, professional and knowing how to hold the reins of the student. These are the best instructors to have, they have learnt how to manage a whole host of personalities and that is why surrendering to the knowledge of the Guru is so important. The Instructor is irreplaceable.

Every Equalisation problem that seems like a world-ending problem will be handled calmly because it is NOT their first time dealing with AND sorting out such issues. Trust your Instructor. You are not a unique snowflake, with unique EQ problems.

The right teacher understands that even if the body may be ready, it is as much a mental game. With Sergei, the PBs and the numbers were never the goals, it was always “What’s your comfortable depth? Let’s make that deeper.” It’s this slow and steady approach that pays off long term, not only is this safer and methodical but more importantly inspires confidence in the freedivers’ own abilities.

This approach is what made me fall in love with the sea, knowing that I could spend almost a minute hanging in zero gravity is something to be experienced, words do no justice.

TIPS I’D PASS ON

DISCIPLINE: Did Jocko just show up in your dreams ??!! If he did, Good. Because at some level this is the only way to go. This section gets into Veteran speak. Falling ill is unplanned, but taking precautions, getting enough sleep, eating well and training hard are in your hands. These may sound trivial, but they are the key, like hydration and sunscreen. The benefits and the repercussions are all yours. Hydrate. Be disciplined. Stay hard. This course will create habits and as Sergei says “It’s easier to teach someone new than to correct old mistakes”.

TIME: Take time off. Have dry days to soak in the sun and a few beers. It’ll take anywhere from 2-3 months to finish and that’s a long time. There will be periods of stagnation, where the ears won’t EQ or it’s just plain exhausting physically. Be prepared mentally, and physically the body will respond.

BABY STEPS: The key I figured was to break down each session into what needed to be achieved today. An increase in depth by a meter at a time is not daunting, 32 meters depth, 70 meters dynamic sounds like a lot, but it’s baby steps all the way. The journey is far more rewarding.

FAITH: Having faith in your instructor and following the military’s favourite training philosophy of “Don’t Think, Do” is the best way. It’s the most uncomplicated way to approach it, you are a sponge, soak it up. There is wisdom in even the smallest of conversations, keep your ears open. Learn the good drills followed.

Looking Back or If I Had A Time Machine.

I would have pushed harder when it came to depth. It’s the one discipline that takes the most effort, logistically and otherwise, boats, conditions, a safety diver etc. There are too many factors that make it difficult to chase depth any other time. I would spend a longer time and try to get to 40 during the Masters course itself. The rest of it, I would not change a bit. Follow your Instructor.

CONCLUSION

What you will remember has very little to do with the classroom and theory. The daily diving, meeting the same group of Masters students, going through the same issues, post-dive hunger et all. Three months of intensive daily diving; That’s a long time to dive almost every day with the same group and celebrate each other’s PBs in any discipline, looking forward to watching a 50-meter tow happen in ripping current, watching every competition like we were next in line, swimming in a sea of jellyfish, doing FIM in a current where the line is at an angle that would make Pythogoras giddy with joy. These are just some of the experiences along the way that will remain as my version of “Back in the day when…., or During my Masters…..”

The greatest gift though, has been comfort in the sea. The sea is no longer daunting, unknown, and scary, she is a place of joy and comfort. Everyday. The confidence to feel and say this, to go and hang at 15 meters and just soak in the nothingness is where the metamorphosis takes place.

The student of Freediving Program Zero to Hero, is the little turtle crawling out of the sand and making its way to the sea. Just like a turtle, the first few years can be quite tumultuous, but be sure that once you go to the sea there’s no looking back.

5 TIPS FOR SNORKELING LOVERS

Snorkeling is the most popular and enjoyable water activity. Even without good swimming skills, many people are signing up for snorkeling tours to explore the unknown underwater world. It is believed to be the safest water activity as well.

But with a few steps, you can make it even safer!

When you go snorkeling with a tour, usually the guide is responsible for the safety, constantly keeping an eye on all of the people he brought to the spot. Moreover, he is always ready to provide necessary assistance in case of need.

Because in the open water, even if you are a confident swimmer, you are not 100% safe. In the case of dizziness or some bad feeling, you can take care of yourself without any side assistance if you are on land. However, in the water, where you cannot even stand, you need someone to help you in case of a problem.

Besides, it’s much more fun to snorkel with friends.

SAFETY RULE # 1 – When you are in the water, someone should be watching you.

The next aspect I would like to highlight is the importance of being visible in the sea.

When you swim, face down, entirely focused on the beauty of the coral reef with your black snorkel next to your dark-haired head, how do you think the passing boats would know you are there?

Even if you are snorkeling in an area with a bit of boat traffic, there is still a chance for bad luck when there will be only one boat driving by, and it potentially can hit you.

There is an effortless way you can protect yourself – be bright!

Bright neon color snorkel, bright red, yellow, or pink, whatever color except blue and black, rash guard, or t-shirt will increase your chances of being spotted by a captain from far away!

Check this bright O’Neill rash guard (Amazon affiliated link)

Moreover, if you plan to snorkel in an area with heavy boat traffic, it is better to have a floating device. They are usually also bright red, yellow, or orange.  Or, if you don’t have any, even your bright color dry bag filled with air and sealed can work well.

SAFETY RULE # 2 – be visible in the sea.

The 3d rule will be about your buoyancy in the water.

After finishing scuba or freediving courses, someone learned that a weight belt is a helpful device for maintaining buoyancy underwater. Well, yes, it is much easier to dive down with a few extra kilos around your waist. However, it is much more challenging to float on a surface with those extra kilos. In scuba, you had a buoyancy jacket to compensate for the weight on a surface, right? In freediving, you have to be positively buoyant on a surface even after the passive exhale, don’t you? So leave the weight belt alone – you do not need it for snorkeling, as you don’t want to struggle with the negative buoyancy on the surface.

SAFETY RULE #3 – be positive on the surface

Further rules go mostly for advanced snorkelers as they deal with some freediving while snorkeling. Still because it is a tiny step from beginner snorkeler to advanced, I recommend you to finish this article, no matter how good you are now.

No wonder that after a while during the snorkeling, you want to have a closer look at some cute underwater habitats. You take a big deep breath on a surface, and you dive.

Do you know what you might forget to do?

You might forget to remove the snorkel from your mouth before the dive. This is a typical mistake even for scuba professionals. Or maybe, it’s just because they feel more relaxed underwater with something in their mouth, who knows.

Why would you need to remove the snorkel before the dive if you can easily blow into it to clean after ascending?

  • you don’t want to waste time and energy on it
  • it might be potentially dangerous
  • There is a chance of inhaling water from the tube.

If you ever decide to take a freediving course, your instructor will explain to you in detail why diving with a snorkel in the mouth could be dangerous.

Imagine yourself swimming up from your dive; you are already a bit out of breath, but still ok, you blow to clean your snorkel, and you fail to clean all the water from it, so you still have water in, and now you are totally out of breath. That doesn’t sound good.

SAFETY RULE #4 – always removes the snorkel before a dive

And the last rule – don’t exhale underwater.

If you have seen in the videos that some experienced freedivers exhale just before they break the surface – don’t repeat this. This is an advanced technique, and if you are not at the same level of experience as someone diving to at least 80 meters, please, don’t repeat it.

Exhaling underwater has no benefits, but it can lead to unconsciousness or damage to your lungs.

SAFETY RULE #5 – don’t exhale underwater

And before I finish, I would like to make sure that when you start some freediving while snorkeling, you remember to equalize your ears.

Freediving equalization is quite a complicated thing. And some people need time to master it. When you take a freediving course, a big part of the course is dedicated to this topic. But if for some reason you prefer to skip the freediving course, at least remember – you do not continue to descend if you have an uncomfortable feeling, or especially pain, in your ears or forehead or anywhere else. Diving with pain may cause eardrum rapture. It will heal after a while as our bodies are perfectly designed for self-renovations; still, you prefer not to damage yourself. Right? To learn more about equalization, check our video about it.

Breathing For Freedivers (Part 1)

Over the last couple of months, I have noticed that even some Freediving professionals do not entirely understand how breathing control in freedivers works. And be honest, while I was writing this article, I found out that I was not 100% correct either.

Hopefully, this post helps you to understand better what exactly happens with your respiratory system when you hold your breath. And if you find any mistake here, feel free to correct me – I am still learning as well!

At Kaizen Freediving, we teach breathing control on our Freediving courses, but here I put more details about the topic.

To understand better breathing control for Freedivers, we start with the basics. We have two types of chemoreceptors, which detect chemical changes in our body and send signals to the respiratory centre. From the respiratory centre, impulses are sent to our external intercostal muscles and diaphragm, to change the volume and frequency of our breathing (or cause “urge to breathe” if you are holding your breath).

We can divide these receptors into two categories

1. CENTRAL CHEMORECEPTORS

Why “central”? These receptors are part of our central nervous system and the brain (located inside the Pons and the Medulla Oblongata). Since these receptors are not inside blood vessels, they respond to high CO2/H+ not within the blood, but within cerebrospinal fluid (CSF), which is separated from the blood vessels by the blood-brain barrier (BBB).

breathing for freedivers (central chemoreceptors)

Let’s make an example. A freediver holds his breath for a few minutes. As the amount of CO2 increases in his blood, the amount of H+ also increases, creating a low pH (respiratory acidosis). H+ doesn’t diffuse through the BBB, but CO2 does. This CO2 bonds with water inside the CSF and produces H+, an increased amount of which is detected by central chemoreceptors.

CO2+H20↔H2CO3↔HCO3+H+

The level of lactate has an impact on this process as well. Lactate, produced during anaerobic energy production, in the form of lactic acid, can cross the BBB, where it breaks down into lactate and H+, eventually leading to the activation of central chemoreceptors.

Eventually, central chemoreceptors can desensitise, which is why we have the potential to become less sensitive to high H+ over a period of training with exposure to a high CO2 (whether it is a CO2 tolerance training or some form of high-intensity interval training).

2. PERIPHERAL CHEMORECEPTORS

They are not part of the central nervous system (instead, they are an extension of the peripheral nervous system) and are located inside the aorta (the largest artery of the human body). More specifically, inside the aortic and carotid bodies. Interesting fact – here we have one of the highest blood flows in the human body.

regulation-of-respiration-14-728

Chemoreceptors inside the aortic body are sensitive to the change of partial pressure of CO2 and O2. If there is a change, they send the signal to the Medulla Oblangata via the Vagus nerve.

Chemoreceptors inside the carotid body are sensitive to changes in the partial pressure of CO2/O2 and changes in pH (metabolic changes, due to high lactate production, for example). And if there is a significant change, send the signal to the respiratory centre via the Glossopharyngeal nerve.

The main function of peripheral chemoreceptors (glomus cells) is control of pO2 (in contrast with central chemoreceptors, where the main trigger is a change of pCO2/H+). As I said earlier, they are also sensitive to changes in pCO2/H+, but these are secondary. It means that the sensitivity of these receptors to the low pO2 is greater when pCO2/H+ is high.

Activation of peripheral chemoreceptors is low when the partial pressure of O2 is close to the normal (100 mmHg), but when it is below 60 mmHg, the activity increases rapidly due to a decrease in haemoglobin-oxygen saturation.

Peripheral receptors are not desensitized over time.

Two common hypoxic ventilation responses (CO2/pH can stay at the normal level) – reaction to high altitude or high concentration of carbon monoxide in breathing air.

BREATHING CONTROL FOR FREEDIVERS

How can all of this information about breathing be useful for us, Freedivers? During the middle part of the breath hold, when contractions begin, it is a reaction to high CO2/H+ levels sensed by central chemoreceptors. Peripheral chemoreceptors are not playing an important role at this moment since the partial pressure of O2 is close to normal. But close to the end of your MAX attempt, when pO2 is going to be close to 60 mmHg and lower, a reaction from them will contribute to your urge to breathe.

How to prepare for a Freediving course. (Swimming)

As the Freediving Instructor I was asked many times – do you need to be a professional swimmer to become a Freediver? And the answer is no, you don’t to be a pro. But there are no doubts that swimming helps a lot in learning Freediving, especially in the beginning.

swimming
swimming for freediving

So, if you are planning to do a Freediving course (find more information about Freediving courses) in the near future and want to be better prepared for it here are a few things which I recommend you to do in the pool

  1. Swimming with a mask and snorkel. Any style – breaststroke or freestyle – doesn’t matter. Benefits – you get used to breathing from a snorkel (and clean it from water), becoming comfortable with a mask and not stressed out when there is a bit of water inside
  2. Swimming with fins, mask and snorkel. Face down, not too fast, not too slow. Same benefits as above, plus you are working on kicking (not bending knees too much, correct rhythm etc.)
  3. Swimming with fins on the back. Improving the kicking technique and body position control. Make sure that your knee not coming up above the surface.
  4. Swimming with fins on both sides. Further improving your kicking style and body position control. Keep your body as horizontal as possible.
  5. Alternating swimming on one side, with swimming on your back. General body control.
  6. Vertical kicking (if your pool is deep enough). This style is close to what you are going to do in the open water

These exercises not going to make you an incredible Freediver, but they will boost your confidence in the water and improve your kicking technique. Here is a short video about the importance of swimming for a beginner Freediver.

How to train DYN for beginner Freedivers

In one of the last post, we discussed how you can train static (in case if you missed it, read here). And what about dynamic?

If for static you can do dry static apnea, then for dynamic you obviously need a pool.

Normally you can learn DYN on any PADI Freediving courses, but if you haven’t done any dynamic on your course, might be this video can help.

DYN Freediving training
DYN Freediving training

When you do static apnea – it is complete relaxation. The same principle can be applied for DYN – relaxation is the key. But in dynamic obviously you couldn’t relax all your muscles (since you need to move forward), but you should relax all the muscles not involved in this movement (neck, shoulders, etc). And even muscles which involved in the movement should be relaxed at the moment when you finish the kick (gliding phase).

Hopefully, it doesn’t sound too complicated.

How often do you need to train DYN? I think 2-3 times per week is enough for beginner Freediver. How intense? Not intense at all! Progress will come naturally.

There are few things about your technique, you want to be focused on. Choose one of them for a session and work only on it (let’s say be focused on your shoulders relaxation

Freediving technique
Freediving technique

the whole session).

How do you know your mistakes? Ask your buddy to film you (GoPro does the excellent job)!

  • Head position (should be neutral)
  • Relaxation in the shoulder area (quite often too tense)
  • Buoyancy (the first thing which you have to fix!)
  • Kicking both directions
  • Start kicking from your hips
  • Not bending knees too much

And here a couple of examples of DYN training

  1. Main training – do short laps with 100% concentration on technique (mentioned above) and relaxation. If you current MAX less than 50-70 meters, do ONLY this training. Approximate distance 40-50% from your MAX. Amount of repetitions 5-10
  2. Easy classic CO2 training. Let’s say 25 meters with 30-60 seconds rest. 10 repetitions. A bit harder than the previous exercise.
  3. Over-under. Swim short distance (less than 40-50% MAX) underwater and without rest, swim same distance on the surface. Repeat 5-10 times. Can make it a bit harder if decrease surface distance.

Sorry to repeat one more time – focus on the technique and relaxation.

Do it for a month and then can try to increase your PB by 5-10 meters.

All the training should be done ONLY with another Freediver!!

How to prepare for a Freediving course

GH010152_Moment2121

Quite often future students ask, how they can prepare for freediving course, which they would like to start in a couple of weeks (or even months).

Of course, if you just heard that freediving exists and you want to try it immediately – just sign up for a course. During the course, the instructor will explain everything you need to know and help you to do all the requirements.

Check out which requirements you need to pass to become a PADI Freediver

But some people always prefer to be one step ahead and well prepared before they start something.

MVI_1849_Moment09For them, number 1 recommendation – spend some time in advance training your swimming skills. Yes, we have fitness requirements in PADI freediving course. But no worries, it is just basic swimming (200 meters without fins or 300 with fins) and can be performed in any style (also without time limit). If you know, that you cannot meet this requirement, then it is 100% better to train swimming skills before. In some organizations, though there are no requirements for swimming at all. Which seems extremely strange.

But even if you know that you are pretty good at swimming, it would be better if you go to the local pool, or even better the sea, to practice. Because more time future freedivers spend in water before the course, the more confidence they gain. Thus in such simple cases as leaking mask or water coming into snorkel students feel less stress. The whole course will be more smooth and you may feel more relaxed if such small details will not disturb you. So the 1st thing you can do before freediving course – remove stress by regular swimming (with fins even better).

The next thing which we recommend to work on is  Frenzel equalization. If you tried scuba or freediving before, you know how and why to equalize. If you are looking for some explanation on how to work on equalization, check this youtube video. Besides, let me know in comments if you have some questions about it.

Indeed equalization in freediving is probably the key point. Even scuba instructors sometimes are facing challenges with Frenzel equalization, because diving head first in vertical position differs a lot from diving feet first. In this concern, it would be useful to spend some time practicing it in advance.

MVI_0481_MomentWhat else can be done if you have a few months ahead before the freediving course? You can do some stretching exercises. Stretching is beneficial for freediving, however, it is easy to pass the 1st level without any stretching at all. But if you are going to do advanced or master course, stretching will be super valuable and will help to make the course much safer and enjoyable.

The 4th thing on which it is better to focus is relaxation breathing. There are plenty ofMVI_0500_Moment mald breathing technics for different purposes. You need to focus on relaxation breathing for freediving (here is the link on basic relaxation breathing routine).

Also, so many people ask what they can read before starting freediving. My answer is always the same – just read a freediving manual. I don’t know about other organizations but in PADI we can provide students with the freediving manual in advance, where you can find theoretical aspects and practical advice.

I hope this information was useful.

And if you have further questions, or maybe, want me to cover some precise topics in next articles – feel free to let me know in comments.

How to start training STA breath hold

First Freediving course is over (if you haven’t done it yet – check here for more details), you are happy and willing to train more to become a better Freediver. The big question – how to train?

If you are lucky, and there is a Freediving club nearby – then just join it. You will find support and motivation there. But what to do if there is no Freediving club nearby? How to progress? Well, this is what we are going to discuss here

IMG_0511First of all – if you are planning to train in the water, you HAVE TO have a Freediving buddy. No exception. What about easy breath holds? Still no, you have to have a buddy in any case! If no – train STA dry (less fun, but safer!).

Before you start – refresh your knowledge about Breathing process in general (at least a part that it is CO2 which caused the desire to breathe, not O2). Don’t know where? Check out our video about it here

The worse what you can do in the beginning – is to start pushing your limits too hard! Why does it? Impressed someone? Because your friend can hold breathe longer? Or is it because 3 minutes sound impressive? Whatever reason you have – don’t do it.

Remember, a huge part of Freediving is relaxation, so, start with it.

But let’s be more specific. Let’s say your breath hold on the course was about 2 minutes. IMG_1180And you want to reach 3 minutes within 3-4 months. Here is your plan (train 2-3 times per week). Choose only one of these exercises for a session

  1. Do 5-7 breath holds, without checking the time at all. Finish every attempt as soon as you feel uncomfortable (urge to breath). Your goal is relaxed breath holds
  2. Do 5-7 breath holds, with start timing only after you start feeling uncomfortable. For example, your safety buddy can count to 10 (or less) after you have your first contraction. The goal is still to stay relaxed even after you have an urge to breathe.
  3. Do easy CO2 tables (more details in the video here). Increase your breath hold time very gradually (only last 1-2 breath holds should be challengeable). The goal is slowly to accumulate CO2 and still be relaxed
  4. Practice relaxation breathing (as meditation, pranayama breathing, and three section breathing). The goal is not to fall asleep.

IMG_1313Have you noticed “PUSH HARDER” advice? No? This is because there is no such advice here! You don’t have to push harder to reach 3 minutes static breath hold!

Stay safe and progress slowly!

 

How to choose a mask for Freediving

Probably the 1st thing your personal freediving equipment starts with is a mask and a snorkel.

freediving maskThis step is easy to explain: rental masks might not fit you well and can constantly leak. Besides, it’s always more pleasant to be the only one who wears the mask which touches your face. Also, you don’t depend on rental shops operation hours and with your own mask, you can go snorkeling or freediving wherever and whenever you want. And the last reason – it’s super easy to travel with a little mask in a bag. Way easier, than with a pair of freediving fins.

So how to pick up the decent mask? If you are already a certified Freediver, probably you know the answer. If not, let me explain

Remember one thing – the best mask for you is the mask, which fits you independently on cost and brand.

Let me give you a couple of advice on how to pick up the perfect mask.

It is always better to try the mask first. Ideally in the water, but at least in a shop.

And there are two main things you ’d better pay attention to mask shouldn’t hurt you and you should be able to equalize in it.

If you put the mask on your face and press on the top of the nose bridge and if you feelDCIM101GOPROG0091796.JPG little pain, this mask is not for you. As little pain can become a terrible headache after 1-hour freediving or snorkeling session.

Another important thing – equalization. Be sure that you can pinch your nose to equalize. Some masks have extremely huge nose pocket, like Omer Zero, and it’s a real challenge to find the nose in such a mask.

Let’s talk about the features, which mask should have to be suitable for freediving.

So, in freediving unlike to scuba diving to equalize the mask we are using our air from the lungs, which is limited and which we actually need to dive deeper. That is why for freediving mask it is extremely important to be as low in volume as possible. And single lens mask has always more volume then double lens one. In this concern, you need to look for a double lens mask. Soft silicone skirt is important as it seals better around the face. And except that it is much easier to pinch the nose for equalization. In this concern, PVC skirt masks are not a smart choice at all.

Let’s take a look at one example of the mask.

mask for freedivingYou might have seen many freedivers diving in Sphera mask by Aqualung. It’s a gorgeous not expensive and unique mask due to its bent lenses, which allows the mask to follow the shape of the face. This provides super low volume and high side vision. But to make the lenses curve manufacturer had to use plastic instead of glass. And plastic is much less resistant to the scratches. That is not a problem at all if you care your equipment well. In case, you have a habit to drop your mask anywhere but not in the box, probably you have to check for another option.

And the last thing which I would like to cover is the difference between brand and noname masks. Brands usually provide good warranty conditions and in case your mask is broken due to manufacturing failure, you can apply for warranty repair or replacement. But be sure you have saved the receipt to confirm your purchase. The best way is to take photos of all your receipts and keep the digital copies in case you lose a paper bill.

I hope all these tips will be useful for you when you come to the shop for your 1st Freediving mask.

And if you have any questions, please don’t hesitate to ask in comments below.

Freediving vs Scuba Diving

DCIM100GOPROFreediving, as a recreational water-based activity (as well as a sport), getting more and more popular. But still, it is far away from other water activities, like for example scuba diving.

There are a lot of myths around Freediving, which stopping people to try it. Or at least confusing.

Let’s try to find out which one is true and which one is not. So, let’s start!

  1. Freedivers can come much closer to the marine life. NOT TRUE. Well, actually it depends. If you compare an experienced Freediver and a beginner level Scuba Diver, then it is true 100%. But if we compare both an experience Scuba Diver and a Freediver, then it is not that simple. As a former scuba instructor, I had a few thousands of dives and I can say that majority of the marine life can come very close to you (reef fish, turtles, stingrays, sharks etc). Less than a half meter. SomeDCIM101GOPROG0154199.JPG people are saying that fish afraid of the bubbles. But why should they be? Fish are afraid of their natural predators and they don’t make bubbles. Fish afraid if you make too much movement and if you are rapidly closing the distance. However, I am willing to accept that some marine life can come close to a Freediver (at least I was told so by other Freedivers).
  2. Freediving is more environments friendly. TRUE. Freediving boat is usually much smaller and requires a smaller engine. And they don’t have compressors. It reduces air and water pollution (as well as noise pollution). All of this makes a difference on our impact on Nature. Also, Freedivers are usually not that close to the corals (especially beginner level), so, fewer chances to damage fragile corals. We are also diving on the reefs less often (mainly we are diving just in the blue).
  3. Freedivers have less equipment. ALMOST TRUE. If you compare Freediving vs Scuba Diving – you will probably think – oh, this is 100% true, but it is not that DCIM102GOPROGOPR3616.JPGsimple again. If we are talking about starting – then for sure it is true! As soon as you have a mask, you can be a Freediver 😉 For scuba, even for absolute beginner level, there is a standard set – BCD, regulator, fins, scuba tank etc. Coming back to Freediving, like I said, in the beginning, you can just invest in the mask and snorkel. But then it will probably be more equipment – weight belt, neck weight, wetsuit, nose clip, safety lanyard, goggles for the swimming pool, float and rope if you want to train with your buddy independently, etc.
  4. Freedivers are leading a healthier lifestyle. TRUE. Some people like to call Scuba Diving sport, which always confuses me. Obviously, it is not. But freediving is. Even if you are not very serious about results. Freediving training combines correct breathing, different relaxation techniques, different physical exercises (in open water, pool, gym etc), as well as mental training. So, yes, if you like to be connected with Nature and stay healthy – Freediving should be your choice.
  5. Freediving is more dangerous. ABSOLUTELY NOT TRUE. Let’s make a line between Freedivers who are properly educated and follow safety rules and someone who has no idea about basic safety rules and just decided that he/she needs to dive deeper or hold the breath longer. Among the first groups, some problems occur, butDCIM100GOPROG0010673. they are not fatal. The second group is just playing Russian roulette. But the same is true for any other activity in our life – you have to follow safety rules. Even for walking. Disagree? Try to walk across a high way! When someone tells that Freedivers are dying regularly, I am always asking where this information is coming from. And there is no answer. Simple because it is not true. So, the bottom line here – follow safety rules and Freediving would be the safest water based activity!
  6. Freediving is a more natural way to be underwater. Well, of course, it is TRUE. We don’t create with the scuba tanks on our back. But we have reflexes which help us to stay underwater longer and dive deeper. Holding the breath for a certain time is natural for us, as well to the other marine mammals.

 

DCIM104GOPROG0549191.So, what would be your choice? Ideally, try both freediving and scuba diving! In my opinion, if you want to explore reef up to 15 meters deep – Freediving is a much better choice. But if you are planning to explore a dive site 25-30 meter deep, then it is easy to do with a scuba tank. If you are interested in underwater photography or videography, then again, having scuba tanks make your life easier. On the other hand, if you want to enjoy to be underwater and also combine it with a healthy lifestyle – Freediving is a better choice.

Freediving problems. Part 1 (LMC/BO/SWB)

I usually ask my students, what do they think, is Freediving dangerous sport or not? And

Freediver in the pool

if it is a PADI Freediver course (first level in Freediving), more likely the answer is yes.

What do you think about it? Stop reading for a second and let me know your opinion in the comments section at the end of this article!

Done? Good!

Ok, let’s start with it – any activity is potentially dangerous. And I am not even talking about such activities as a base jumping or rock climbing. Walking on the busy street can be extremely dangerous, right?

However, if you follow the rules of this particular activity – risks can be dramatically minimized (don’t walk on a highway for example). And Freediving is not an exception. Follow simple safety rules and Freediving would be the safest water based activity!

But I would lie to you by saying that there are no risks in Freediving. Are they big? Let’s have a look.

It is going to be two parts about most common problems in Freediving.

First one about – LMC/BO/SWB

IMG_0511And second is going to be about lung squeeze, DCS/lung overexpansion/gas narcosis

 

Before we start – it is very unlikely that you are going to experience it on your Freediving course (especially on the first level – chances close to zero). But with the experience, you are going to be not that much distracted with a high level of CO2 (you still have contractions, but you are going to be more ok with them) and able to hold your breath longer and longer. And longer your breath hold is, less O2 it is going to be at the end of it. And less O2 you have more likely problems can happen.

Let’s say a Freediver decide to do his PB (personal best attempt). He is relaxed and enjoys his breath hold. At some point, contractions (involuntary movement of respiration muscles) will start. But he is still relaxed. He has them before and he is not freaked out, everything is under control. Contractions become harder and harder, but he is still holding his breath. At some moment, contractions became unbearable and Freediver comes up. But because the level of O2 reached the critical level, there is a chance of LMC (loss of motor control). What happens with this Freediver if he has an LMC?

20180201_074458He is still conscious; the heart is working, blood still circulating through the body. But the partial pressure of O2 is too low for normal functioning. He is not fainting, but close to it. Signs can be small (blue lips, light uncontrolled eyes or head movement), or big (body shaking and losing coordination). What happens when a freediver lose coordination while he is in the pool? Big problem…

And this is why your buddy is very important! Safety buddy is going to grab the Freediver, provide support, remove a mask from the face (or nose clip) and encourage him to breathe!

 

HOW TO AVOID LMC?

  1. No hyperventilation before any breath hold
  2. Don’t push too much (be moderate with your progress and don’t do big jumps in it)
  3. Secure support (float, pool’s edge, your buddy arm) after surfacing
  4. Proper recover breathing after stop holding.
  5. Don’t do PB’s if you are dehydrated, too tired, you haven’t slept well, it is your second training per day etc

AND NEVER FREEDIVE ALONE!

HOW TO DEAL WITH LMC?

  1. Support your buddy, making sure airways about the surface
  2. Remove mask/nose clip
  3. Encourage to do recovery breathing
  4. Be ready to deal with BO

DJI_0760_MomentIf you have an LMC, take it as a lesson, stop training for at least a day, analyze why it happened and don’t repeat the same mistake 😉

 

What is BO? In Freediving we call it a situation when Freediver lost his conscious due to hypoxia (insufficient supply of O2) during the long breath hold. There is a difference between hypoxia and anoxia – complete deprivation of O2 supply. Why it is important to understand this difference?

Anoxia is extremely dangerous because some of our tissues could not survive without O2 supply even a couple of minutes (brain as an example). During hypoxia there is still available O2, but not enough for normal body function. And the protective mechanism launched – Freediver experience blackout.

 

HOW TO AVOID BO?

  1. Don’t do hyperventilation
  2. Do recovery breathing after any breath hold
  3. Avoid pushing too much your limits (especially if you are a beginner)
  4. Don’t depend on the watch, if you feel that you need to stop – stop!
  5. Have enough time to recover between Freediving sessions
  6. Don’t train when you dehydrated

AND NEVER FREEDIVE ALONE!

 

HOW TO DEAL WITH BO?

  1. Learn rescue skills under professional supervision
  2. Practice these skills
  3. If your buddy has a BO – don’t panic, you can easily recover himDCIM100GOPROG0030109.JPG
  4. If you have a BO – stop your training for today
  5. If there is a chance that you inhale water – look for a medical checkup

 

As you know, BO happens when there is not enough O2 for normal buddy’s function (when a partial pressure of O2 below a certain level).

When we are diving, pressure changes very fast, compared to the surface. When we are only 10 meters deep, pressure increase twice (2 atm), 20 meters – three-time (3 atm) and so on. Same happens with the pressure of any gases in your body, include O2.

Deeper you go higher partial pressure of O2 you have.

But now you turned 😉 And while you are ascending, you are still burning down O2, but now also pressure decreasing. And on the last 10 meters, it is going down twice. And this is where the majority of SWB happens (some of them even on the surface).

 

swb2It is almost the same recommendations which I wrote about how to avoid BO! let’s repeat

  1. Don’t do hyperventilation
  2. Do recovery breathing after any breath hold
  3. Avoid pushing too much your limits (especially if you are a beginner), in case of SWB – don’t progress with depth too fast
  4. Don’t depend on the watch/depth, if you feel that you need to turn – turn!
  5. Have enough time to recover between Freedives (apply the rule, surface interval 3-4 longer then dive time or more conservative time)
  6. Limit the number of deep dives per session
  7. Don’t train when you dehydrated

AND AGAIN – NEVER FREEDIVE ALONE!

 

What to do if your buddy has SWB

  1. Reach the diver
  2. Grab him
  3. Bring to the surface
  4. Remove the weight belt if necessary
  5. Blow-tap-talk for 10 seconds
  6. 2 rescue breath and ask for help
  7. Start moving the diver to the boat/shore, providing 1 rescue breath every 5 seconds
  8. Remove from the water and start CPR
