No Dive experience but I am signing up for Master course.

I would say focus on technique first. Times and depths will follow... if you focus only on time and depth to start you may not get the results you want and be disappointed.

Studies say that only 20% of first time students are able to equalize successfully.

'Focus and Tecnique', Good to know. Thanks.

Somehow the numbers, like time and depth, seem to be the easiest thing to imagine. Everything else is so much more complicated to think about, at any particular moment.

I must give the impression, here, that 'deep' is all I care about. Pretty shallow, I agree!

A lead weight around the ankles would get the results if depth was the only thing.

But great technique is so important.

'Only 20% are able to equalize successfully'?!!
If I am not one of them then that would certainly mess up any personal progress!

-How can I ensure that I am able to equalize, okay?

 

[BennyB]

Static/Dynamic abilities and depth abilities don't always correlate. Just look at Sara Campbell as an example - World Record depth dives in the 90's and a couple of attempts to 100m, but static is pretty ordinary in comparison (around 5min'ish when she's really busting a gut).

Just chill out and do whatever you do, you'll put less pressure on yourself that way and you'll likely do better than you the target you would have set yourself anyway.

Cheers,
Ben

 

[Arcticnick]

Arcticnick you appear very preoccupied by the depth and time...

rather than us try and tell you what you should be able to diver to (impossible) please tell us WHAT YOU want to dive to.

you obviously have a number in your head which you would like to get to, what is it? and in what time frame are you wanting to see results.

the reason i say this is because in reality there is no real reason why given the dedication and time you cant challenge the swedish national records (very serious dives) or even world records the bottom is the only limit we have as divers.... and as a friend always says "when you get to the bottom? take a shovel down and dig deeper"

best of luck with your journey and i know of said it before, dont get caught up in the numbers they will come when the love for the dive grows the dpeths wil grow as well.

ALSO you also have a VERY strong group of Freedivers in Sweden, why not start your training there first with a Freedive Biz course before travelling over seas, get some practise in soyou hit the water kicking when you travel. Sebastien on this forum has soo much knowledge to offer it would be a shame not to gain as much as you can from him when he is so close to home for you.

Hiya DivingDane,

Good to hear from you again.

30 and then 40 meters!
Those were my goals before I started to research.

island_sands
Said:
'Studies say that only 20% of first time students are able to equalize successfully.'
Suggesting that depths over 30 or 35 meters for many is not possible

...so... 30 meters, is my goal!

Someone even suggested 75 meters was not unrealistic....so...now, 75 meters!

Of course 30 meters is of special interest to many who still use a measuring system straight out of the dark ages. And it is believed to be, at least in part, why those using the alternative metric scale, frequently make more reserved scuba divers, in their pre dive profile planning, as they are not trying to break some arbitrary goal.

Perhaps I should first admit that I am not Swedish. I am a Brit, although I don't feel very British most of the time.

If I had known about the state of Swedish freediving earlier, (I didn't know anything about any kind of freediving until about one month ago) and if I could understand Swedish (I am a true Brit in that one regard, at least, and so have a fantastic inability to speak other languages) then I would have investigated signing up, to do some courses, here, locally. Sebastien sounds like a mine of knowledge, (any tips Sebastien, please?)

It is a bit late, though.

I have lived reclusively for seven long years, near the Arctic circle, (and you think 40 days and 40 nights in the desert is a long time?) and am extremely keen for a change.

As it is, I am desperate to get 'the hell out of dodge', and will be on the plane to my new life in just over one month, as tomorrow I am planning on re scheduling my flight and bringing it forward another 5 weeks.

I have been patient for such a long time and now I only want to live go and in Thailand, and dive.

Now, having developed this freediving bug, I feel like a 17 year old, all over again. It's a great feeling. I was beginning to feel old and tired and now (with some hard work) I feel young and fit and alive, again.

I had the same feelings, 20 something years ago, (when I really was young and alive)...signing up as a total non diver, to complete back to back courses, until I became an active PADI Divemaster for the same shop, who then employed me to work, day in and day out.

Not obsessive, I think. Just super enthusiastic.

When working I always believed I was a high profile example to those I was diving with and my single deepest scuba dive was to 149 feet. I was very careful not to break my limit. I wanted that reserve to be a simple example to others, and a quiet moto for myself.

In the same way, when I sink my teeth into something, like a project or complete life style, I tend to become single minded. I think that the freediving world is just the challenge and concentrated self discipline that I need. Maybe, if I spend enough time, I could get really good but also hope to learn enough, so that I can judge how to practice it, with a realistic degree of safety and reserve.

I just sent off a reply to another contributor to this thread. In it I wrote, how, as this whole topic is revolved around the single question of breath-holding time, it probably appears that I have some obsessive quest for the deep. It is, I hope, fair to say, I only have a healthy interest.

Much as I would love to master the extreme depths I have the rest of my (hopefully long) life to work towards that goal, and I am in not anxious to find my limits for either depth or life.

All the best.

Nick

Hi Nick

Since you are persistent I'll give you a hard time
2:16 is a mediocre breath-hold for a relatively fit person. My guess is you need to relax. That said - your static hasn't all that much to do with diving.
I never practice statics (I've done two static sessions - one when I was sixteen and one last spring - its the most bloody boring and uncomfortable thing.

Hyperventilating will kill you because it A: Decreases your ability to actually use the Oxygen you have and B: Suppresses the urge to breathe. In the beginning it seems to give you longer breath-holds because it staves of the urge to breathe. In the water this can result in a very abrupt blackout.

Equalizing is the first barrier - then at between about 25 and 35m it becomes an issue again.

Lung squeeze can also kill you - so just powering your way down to 40 m without acclimatization even if you can equalize is not smart.

In addition to fast equalization in a head down position you will need to economize effort - using only the muscles needed - and relax deeply. Most really deep divers either practice Yoga - or some yogic exercises in order to gain the ability to relax and maintain flexibility of the lungs and rib cage - these include the yogic bandhas - or locks used in pranayama, and other systems like Qigong, Taijiquan, Bagua etc.

Most of my life I have dived in less than 15m of water - and I've had a great time. Recently I have been able to start working depth - which is another kind of fun and very enjoyable.

It sounds like you've a bit of cabin fever and are just getting spun up about a new thing - you'll do fine as long as you get in a good course.

 

[Erik]

However you go about this, enjoy it.

 

[Arcticnick]

Not only your equalisation ability will determine your depth, other factors as well. I think chest and diaphragm flexibility is key too. As well as the ability to relax while being in the cold dark high pressure environment so far from the safe surface.
The 50m cdavis mentioned is I think way to positive thought. Beginners should be happy with 10 - 15m, advanced should be happy with 20-35. When you're able to do that after these 6 weeks I think you've done a GREAT job!

Like stated above, practice makes perfect, you'll need time to teach your body, and your body needs time to learn and adept.

The best approach I think is to practice what you can before hand, take things slow, ENJOY the new sensations, close your eyes and fall in love with embrace of the ocean.

One little anecdote:

When Umberto went to Jaques Mayol to further his already impressive apnea abilities, Jaques told him to leave all his gauges and watches at home. He told Umberto he would not need them since he was going to teach him how to become one with the ocean. - The point being that true freediving has not to do with numbers, but about the relation one has with the ocean.

--- paraphrasing, anyone please correct me because I'm unsure about the last line.

Another thought:
I recently decided I want to become a licensed freedive instructor. I deliberately seek to be taught by many different instructors because I want to know many approaches and points of view in order to be able to communicate and teach to more people in the most effective and rewarding way.
Maybe even more than scuba diving, I think teaching freediving requires an even wider and sometimes deeper knowledge.

Love, Courage and Water,

Kars

Hej Kars,

I have discovered myself, in the water, once before. As a scuba diver. I am so ready to re discover myself again, now as a free diver.

Thank you for your moderating view, on this discussion about depth.

I am only wondering what some of the realistic possibilities are but have, here, a huge range, varying from between 10 and 15 meters, to 75 meters.

I guess I will have to discover, slowly and sensibly for myself.

Like you, I think that I will seek the knowledge of as many different experienced divers as possible. Sounds like a good approach.

Also, I agree, (with surprise) that freediving 'requires an even wider and sometimes deeper knowledge', and is considerably more involved and complex than scuba diving. Maybe, in part, because mechanics are easily defined (relativity speaking). Human physiology and psychology, much less so! Plus you know PADI!!

I suppose, in freediving, because there are no mechanics to focus upon, then there is only one alternative on which to concentrate. Everything else!!

The knowledge of human physiology when I was teaching was much more limited than today. (God, don't I make myself sound old?)

For instance, we had no knowledge of the lungs filling with blood plasma beyond 30 meters, or any other depth, for that matter.

As for your request for someone to correct the quote from the conversation between Umberto Pelizzari and Jaques Mayol, in their quest to 'further his (Jacques') already impressive apnea abilities' …
I am in the process (a long one, forgive me) of torrenting 'The Big Blue'. I will let you know the full quote immediately I have completed the download. It will take some time, though, so don't hold your breath.

Good luck to you in your quest to become a licensed freedive instructor.
I am sure you will do brilliantly. And this time, do hold your breath

Many Thanks.

Nick

'Enjoy' was going to be my middle name, but they called me Kingsley, instead!

 

[Kars]

Thanks for you kind words Nick, worthy of a British gentle man I think

Well the 75 is in regard to dynamic, distance swimming with fin(s).

I think it's best you develop with a good instructor a plan how to go about exploring this sport.

I suggest you use your cabin time, and ask you to do some soul searching and see if you can come up what aspects you like about breath-hold diving. From this list you can start. First you need to know what you need in order to achieve your wishes. Things like, swimming technique, flexibility, mental focus ability and relaxation ability quickly come to mind. Many of these things can be practised safely alone on land. With an able coach / instructor / freedive buddy you should be able to get you mind and body ready for the big blue waters, where the things you've learned will come together and you'll appreciate your preparations very, very much.

Learning freediving happens in stages. These are determined by physiological and psychological factors, such as 'residual lung volume barrier' and 'contraction phase'.
You'll encounter your own particular set of 'challenges', and you'll need time to learn, adapt and overcome these. Each time you do, you grow, and that's very addictive!
As you start to learn now is that freediving contains a lot of challenges, learning and teaching your own mind and body.

I use goal setting and numbers to have more self discipline. I need to have a steep challenge in order to have focus.
In training I use some numbers to ensure laps of technique practice.
However, when it comes to personal bests, I know that my best dives are those where I was able to turn low the conscious controlling mind, loose the sensation of time, and just enjoy the ride from a sort of mental 'back seat' position, allowing my subconscious to do al.


The better freedivers actually try to retain the CO2, not lower it.
- Thank you Fondueset for making the Hyperventilation point very clear!


btw the Jaques Mayol 'quote' I paraphrased was not in the movie "The Big Blue".
Also take note that this movie is a movie and NOT a documentary. Apart form the names both characters are very fictitious. - try to get the long European version, it's better than the American.

Love, Courage and Water,

Kars

 

[Fondueset]

I had a 'hard-core' moment back there.

I blew out the neck of my favorite wetsuit back in november - so I've been diving in the pool all winter - doing dynamics (30x50yards in 50 minutes) with monofin or no fins - if there are no other swimmers in my lane.

Nick - relaxation is the big one - that and easy equalizing will get you in the door smoothly - from there its just more and more fun all the way down

Back in 2006 I was luck to dive with some wonderful divers in British Columbia - back then 10 meters seemed deep to me - 3 days later I was shooting video at 15 meters and didn't even know it (no depth guage). At that time I decided I wanted to be as comfortable at 30 meters as I was then at 10.

Pretty much there now - and thanks to some of those divers. My criteria wasn't just to get there - but to have the leisure to hang out and take a few pictures. I've found since I really enjoy the process of going deeper - the psychological challenges are awesome and I take less and less with me each time.

 

[demasoni]

If I take it seriously:

-I would like to know what kind of times and depths I might realistically manage.





Hej Demasoni,

Thanks for your thoughtful support and encouraging words.

Thank you, particularly for risking your opinion in such a sensitive and politically charged arena

It is not often that people say what they really think, especially in public. It is good for me to start learning about argument for hyperventilation, also.

You say, '4-5 minutes'. That sounds like forever!

30-35 metres sounds a bit disappointing, though.
I am anticipating spending many years regularly practicing freediving (I usually immerse myself fully in whatever I happen to be doing) and so hope that I will become truly fit, developing the required mental and physical techniques so that I will overcome the hurdles, like equalizing.


-If I can hold my breath for just 2:16, (with little practice) do you think I could realistically do a static 4-5 mins?


-Can you tell me, please, what % difference does hyperventilation make on time/depth, over other techniques?


-Can't the Frenzel technique be applied whilst using a nose clip, even at 30+ meters?


- What's the big deal with equalizing at depth, when the greatest depth/ pressure change is nearest the surface?


- Is the Valsalva maneuver no use at depth?


-Can you tell me anything about any other barriers?


-Residual volume?


-What are PFI and FII, please ?


I am excited to imagine how my new u/w world will develop over time and, of course, part of that is to improve my dive time and depth. I wouldn't be normal if I didn't have some eye to my max potential. Well, I am glad to report, that I am not normal...but I am still interested in what I might one day accomplish, in freediving.

More thanks, in hopeful anticipation I appreciate your opinion.


Mega-regs.


Nick

First of all, let me clarify, I don't advocate hyperventilation at all. What I meant by correlating static time with hyperventilation is that when you take a course, they typically teach you some sort of hyperventilation. Call it whatever you want - ventilations, purging, whistle breathing, hurricane exhales etc - in order for you to make a big jump in progress in a short time. This is not really a secret, but with hyperventilation you can get to the 4-5 min mark easily. There are better ways to do it, but it just takes longer. So, please just be aware of what you are learning and try to enjoy it.

Read up all you can on hyperventilation using "search" and yes, you want to retain CO2, so just normal relaxed breathing for pretty much everything. However, you'd be surprised how many people hyperventilate for static in order to delay contractions.

At some point, keeping everything cerebral and theoretical may have a negative effect on your psyche and you could psyche yourself out before you even get to Thailand. Remember, you can't purchase improvement in freediving, it just takes time.

Good Luck man.

Hi,
At Apnea Total you'll do some classroom work for an hour or so starting around 10-10.30am. You'll learn about breathing, safety and what to do and what not to do in the water. They have their own boat so after class you'll walk across the road to the beach and head out to the dive site, about 10 mins away.
The instructors will set up the lines and floats and you'll be paired up with a buddy. In the beginning you'll be in the water with an instructor the whole time who will accompany you under and give you feedback. I think the maximum dive is 12-15metres.
They have all the equipment you need.
In the advanced class you'll learn more sophisticated breathing techniques and more about your own physiology - contractions, equalising, lung squeeze etc. The dive line is around 34 metres and you'll have an instructor in the water with you. As you progress it'll be just you and your buddy. There is a big emphasis on learning to freedive so as to minimise the risks.
You'll also do training for statics in the sea in shallow water.
Monica and Eusbio want you to love freediving as much as they do. I got to use Eusbio's cool watch so i could see my depths and Monica let me use her amazing long freediving fins.
I also want to get AIDA certified. But you need to be super fit. So i plan on doing the Apnea Total Masters course and then going somewhere else (Egypt) to get certified. I also think it's important to learn from as many people as possible.
Good luck!
Sherrin

Hi again, Sherrin,

Thank you for spending the time to flesh out a typical dive course day, at 'Apnea Total', as well as providing specific information on the different courses, too.

As you know I want to have something to visualise, and now, with your kind help, I can 'see' some of the processes much more clearly.

The team at AT sound like good people, and fun, too. I think that makes a ton of difference. After all I don't want to feel like I am back at school!

It sounds as if everything there is immediately available, like the ocean, boat, dive site, equipment, etc.

Plus a 10-10:30 am start sounds pretty relaxed!!

With your helpful recommendation I am very seriously considering selecting 'Apnea Total' for some of my training and am very keen to get started.

-I think it was you who mentioned, that Monica and Eusbio were not around much, until you made a specific request that they teach more.

-Do they both usually teach part of each course, please? (or just Master classes?)

-Do trainees, of the Master diver courses, assist students of the other classes?

Good luck with your AIDA certification. Egypt sounds like a great place for such a course.

Many thanks.

Nick

Hyperventilation is a double edge sword, with both edges equally dangerous. The first dangerous effect is that it suppresses the urge to breath. You may think it is just perfect, and exactly what you are looking for. Mistake! It just decreases the safety margin you have, and suppresses natural oxygen preserving reactions (DR). The second biggest problem is that it shifts the Bohr desaturation curve (controlling the binding of oxygen by hemoglobin), hence decreasing your tolerance against hypoxia. In other words it decreases the safety margin yet again, this time from the other end. So the effect of hyperventilation is that you will black out sooner or later when trying to increase you breath-hold time yet again. And since you seem to be excessively concerned about the numbers, you are a very good candidate for this to happen.

Be careful and stay safe

...So the effect of hyperventilation is that you will black out sooner or later when trying to increase you breath-hold time yet again. And since you seem to be excessively concerned about the numbers, you are a very good candidate for this to happen.

Hi Trux,

Why am I such a good candidate for black outs? Because I have an interest with numbers? It is true, I do have some interest in technical stuff, facts and figures but why does my interest show me out to be obsessive?

I thought I had created a simple discussion thread, responding diligently to all contributors, and asking lots of newbie questions. I did not expect to be viewed as fanatical and obsessed? Surely my attempt to understand opposing arguments, has told you something of my real intentions.

I should think that only when armed with the right information would I be in the best position to decide how to train, and with whom. Training, with an open mind, whilst doing a ton of research, seems to me to be a good base on which to make up my own mind...as I go. If I get hung up with a few numbers and some raw data, before I even get started, then so what?

Initially, I simply posted a question about breath- hold time, in another post. I had hoped that I helped to keep an interesting discussion going, and now you suggest I am obsessive.

10 days ago I had no previous idea about max breath-holding times, and although I still have no firm idea how the discussions might later relate to me, in real life, at least I understand much better now, some of the theory involved, and hope that some others here might have a better understanding, too.

I have to admit to feeling a little resentful when you cast me as a prime candidate to kill myself, underwater. After all, I just want to know realistically what to expect. It would be foolhardy of me not to!

There must be another reason for you thinking this way.

-Why do you think my interest is obsessive and (presumably) your own is not?

Was, your opinion, maybe, triggered by my recent discussion about possibly training with 'Apnea Total'?

By the way, Trux, I have to stop for a second and say that you have provided here, the most concise explanation for HV I have ever heard. It seems a very strong argument for not using such a technique. It is becoming apparent that HV is dangerous and I appreciate that you are simply trying to let me know that.

But I still have to disagree with you about me having obsessive concern over numbers

I plan to be chatting with you, here, in many years to come, proving to you that my very first post on this forum was in fact, only naïve, enthusiastic, interaction, and not necessarily an indication of any particular diving principal and suicidal inclination and then I shall remid you of this conversation.

I should close this discussion now, just in case I seem to be becoming obsessive but I would be happy to discuss this further, publicly or privately, if you would like. It might help to highlight some points and clear up some issues.

All the best.

Nick

Well, I did not tell anywhere you are obsessive. But you are too focused on the maximal performance you can achieve, started several parallel threads asking for your limits, you want to achieve the maximal possible performances in record time, you are looking for shortcuts (the hyperventilation being just one of them), you want to become freediving guru within 6 weeks, you are leaving your life behind you and moving to Thailand, you take several consequentive courses to reach the maximum time/dpeth as fast as possibe, ... - all those are indicators to me that you are acting very passionately. It does not mean at all, that I condemn it. There is nothing wrong with it. Quite oppositely, the courage and the determintation are admirable. However, the passion may blind you, so you should be double careful and listen to others, more experienced, carefully.

So my advise would be very similar to all the others you already heard here - instead of trying to figure out what depth, and what time you will achieve in 6 weeks, and how many AIDA stars you'll have by that time, focus simply on the plain joy of freediving, and on the peace of mind it brings. Excitement is nice too, but it is not very well compatible with freediving.

It is true you never said I was obsessive. I thought that it is what you implied, though.

Amongst other jabs you did say that I am
'too focused on the maximal performance you can achieve in record time, you are looking for shortcuts (the hyperventilation being just one of them), you want to become freediving guru within 6 weeks, you take several consequentive courses to reach the maximum time/dpeth as fast as possibe '.

-They are judgmental statements which together imply obsession. If not obsessive then what?

How can discussing hyperventilation be a shortcut if when I asked about it I was unaware of any alternative?

You are a good observer of human nature, at least in my case (plus I did say so here) that I do sometimes get single minded about things that I am passionate about. That can be a good thing, as it helps me find drive and motivation, but I recognise that it could be a problem too, if something else like depth became the goal.

I am already much less interested in becoming an instructor. I better understand the standards, knowledge and practical experience required, and realise that instructing would be far more involved than I ever thought. It would also be wrong to think that I could achieve it in 6 weeks. If at all.

I have already indicate in previous discussions that I have just started in this new world and my knowledge has increased 50 times in that short time. But how do I come across as wanting to be a guru in 6 weeks? My plan had been to do lots of courses over an extended time.

-Why can't I try to appear intelligent and not worry about looking like a wannabe guru?

I do hear what you are saying, and it is true that I started parallel threads about limits, but I am only expressing an interest in my new passion. If I wasn't talking about these things then I would not know how to get a discussion going. This is an interactive forum and I wanted to interact with some real people, and read a lot, around the edges. And that is what I am doing.

Of course you understand that what you see here is just a snap shot of the real me. There are other aspects which you can't see.

As I begin to discover that there is more to diving than just holding my breath and going for it, I shall be able to have discussions about some of the more subtle aspects. Like dive politics for example.

I am very glad that my posts have been responded to so well as I am learning lots, from people with considerable experience. Depth is a concept I can grasp and, for me, a great ice breaker. From the discussion of depth have come many other subjects, some of which we have begun to touch upon in earlier threads.

I admire the talent and hard work that many of the contributors, here, display. There seem to be no short- cuts. I would love to earn a place in their ranks, but I probably possess few, if any of the required skills.

-Whilst rubbing shoulders with the Gods here how can I show genuine interest without coming across as wanting to be an instant, 6 week guru?

I seem to have touched a nerve somewhere.

When I asked the question about hyperventilation I had no knowledge of any alternative.

-Why do you so actively discourage me to discuss things like limits?

Surely that is one of the first thing you teach. The dos and don't s.

You tell me that passion may blind me. It also might not, though.

'Excitement is nice too, but it is not very well compatible with freediving '
You indicate that being excited about freediving is an oxymoron. That one is not possible with the other.

Why would it be a problem if I was excited or not when I dived?
Presumably the main problem is that excitement would effect my dive time, which should not be a concern, I thought.

I bet that the first time you went free diving you tried to see how deep you could get. If not, at least you thought about it. A lot.

Surely we are all goal orientated. Isn't that how we 'progress' on this planet? That doesn't mean that we are all about to tie lead weights around our ankles and jump off the deepest ledge.
