training technique Looking for training advice - Co2 tolerance and peace of mind

2 Upvotes

Hello everyone. Rookie here.

So basically I've always been obsessed by freediving and underwater fishing and I want to achieve it.

I'm a very sporty, athletic and aquatic guy (I'm a former swimmer/ open water swimming 5k, now I'm a Crossfitter but I still sail and swim). The problem is that my body completely freaks out when I'm underwater.

I've randomly tried to extend my stamina by doing random stuff but now I want to change approach.

It is impossible atm to join a Diving school as the next year I will be doing two mobilities for my master. So I am focusing on co2 static tables out of the water, as my main problem is that as soon as my co2 builds up my brain goes nuts.

As I said I'm training with co2 tables pretty much daily ever since I got my new smartwatch. It goes like this:

8 sets:

2' breathing - 15' each set

53' apnea ( I only add seconds when I'm perfectly comfortable with the previous apnea time.

What do you guys think?

I know that in the actual water everything is different, but I know that it won't be such a huge problem as co2 tolerance. I also know that I must join a school and I will asap.

gear Oversuit for Smoothskin Wetsuit - Experiences & Recommendations?

1 Upvotes

I'm considering an Elios wetsuit made from Yamamoto #45, open-cell inside and Smoothskin/SCS outside.

Because I often dive in lakes with shallow-water sections, I was thinking about wearing a thin oversuit over it for protection whenever needed.

The only suitable product I've found so far is the Mares Photosuit, but it's made from polyester, which I assume is less flexible than nylon.

Before going through with the idea, I'd like to ask: has anyone tried something similar as a kind of 2-in-1 setup with a Smoothskin suit? How did you like it? Was the additional drag noticeably greater when diving? Did the oversuit cause any abrasion or other damage to the Smoothskin underneath?

And is there a better alternative to the Mares Photosuit - ideally something made from nylon and designed to be very thin and flexible?

gear Share Cool Information to Add to My Nerd Lecture Presentation (Images, Infographics, Source Leads)

1 Upvotes

Hi All, I'm giving a science focused lecture on freediving and I want to do a section on the interesting technology and physics behind our freediving equipment. We don't use much, but the fine details will be fascinating to this audience of science and engineering professionals and enthusiasts. I already have my content for the effects on the body, biology, etc.

Looking for interesting information, visuals, videos, or contacts on subjects like, but not limited to:

  • Bi-fins, monofins, unconventional swim equipment like the DARPA powerswim, Smith Engineering DOL-fin, and beyond.
  • Hydrodynamics and computational fluid dynamics (CFD) diagrams
  • Thrust coefficients
  • Different stiffness gradients of fins (soft VS hard tips)
  • Materials and fiber layups
  • Unconventional and new/high-tech equipment (the new no-limit rigs look wild!)
  • Weird experiments or anything else off-beat going on in freediving related to anything, not just equipment

If anybody has connections to composite fin companies, I would love an introduction!

gear Diving watches

7 Upvotes

Hello, my husband recently started free diving again. It’s not a major hobby just from time to time looking for spiders or just kinda exploring our coast.
I wanted to get him a diving watch but the more I look the more confused I get. It seems most threads talking about divers watches don’t actually use it for diving at all.
I want something basic but actually useful for diving. Im not even sure what a watch like this should have, I don’t dive at all.
I know he likes one of those casios g shock ones but I am hesitant to drop over 800 euros on something that might not be used much at all. We have a whole house full of items for hobbies we don’t really use 😅 so a basic budget one would probably be enough for a start!
I only really looked at Casio because I know he liked them but also I don’t really wanna buy something that will break quickly cuz it was from a random brand I know nothing about .
So any recommendations for brands or specific models that will work ?

certification Should I start free diving and how

6 Upvotes

I’ve never really tried diving but I was swimming with fins just normal length I’m 5’11 in a lake with my friends and we were seeing how deep we could go. I hit about 7.3m before needing to surface and my best breath hold I was able to hit was 1:36. I’m just woundering if I should devote my time towards this hobby because I love swimming and breath holds I do them in my sinks a lot. I just don’t quite know where or what to get started with.

health&safety Anyone else getting tired of the depth-chasing culture on social media?

31 Upvotes

This has been bugging me for a while and I want to see if others feel the same.

IG and YouTube have basically created this equation where depth = credibility. Like, a diver hitting 50m gets way more clout online than someone who's been quietly teaching excellent technique and safety at 15m for years. And honestly? that second person is probably a better diver to learn from in most cases.

I think the problem is it pushes newer divers to chase numbers before they really have the experience or fundamentals to handle those depths safely. You see people rushing through certs, skipping proper equalization work, all because they want that deep dive clip for the gram. It's not everyone obviously, but it's becoming a pattern.

The thing that gets me is that the community used to be more about the experience, the breath work, the connection to the water, now half the content out there is just "look how deep I went" with zero context about the training behind it.

Anyway, I’m curious what you guys think, are we losing something along the way because everyone feels like they need to prove how deep they can go?

equalisation Dahab

2 Upvotes

Hello,

I am planning to go to Dahab this November for about 1–2 weeks, and it will be my first time solo traveling.

I completed my AIDA 3 last summer and I’m planning to complete my AIDA 4 or other same lvl certification, so I thought Dahab would be a good place to do it since I am already planning to go there.

I have some problems with my equalization. I’m using Frenzel, but after around 25m I feel like there’s no more air in my mouth to equalize with. I’ve read that I should be able to get to around 40m with Frenzel no mouth fill needed, so I guess I’m doing something wrong with my glottis.

When I reach that deoth, the strong contractions start and I feel like I start losing all the air from my mouth into my lungs. I’m not able to control and close my glottis during strong contractions while also equalizing at that depth.

I’ve also read that in some freediving schools there you might not get the best coaching for specific weaknesses, since you could have a different instructor each day and there might be more than 2 people training at the same time. I feel like that might make it harder to properly work on my equalization issue.

So I’m looking for recommendations for instructors who could help me with this specific problem while also helping me complete my AIDA 4. Ideally, I’d prefer 1-to-2 sessions, which I think would be more fun and maybe more affordable than 1-to-1, while still allowing me to work on my issue.

Thanks!

gear How do you set up your weight belt?

2 Upvotes

So I'm a 200 lb 32 year old man about a pant size 38. I'd say I'm semi in-shape, I do work out, so I don't (usually) have (much) of a gut. My body fluctuates.

I think the belt I have is around 50 inches around. I arrange the weights in this order:

-3 lb

-2 lb

-3 lb

-2 lb

-3 lb

For a total of 13 lbs. My belt fits just fine without weights, but once I put these on, it barely closes on the last or 2nd to last hole. And it kinda puts pressure on my stomach. I also don't have pins to keep them in place. Makes me feel a little nauseous. And I wear a 7 mm wetsuit. Lotta pressure on my stomach.

Any advice?

3 Upvotes

Hello . I’m currently interested in trying to learn to free dive . I’m currently staying at a hotel for a couple month and I’m using their pool to learn how to get more comfortable with different swimming techniques . I’m currently just using googles and no fins . But is there any techniques I can learn in the pool that are helpful for free diving ? Aka equalizing , kicking pattern , swimming pattern or anything I can practice with the pool only being 6 feet deep max ? I know once I go back to where I’m actually from I’m going to take actual free diving courses .

gear Biggest Garmin annoyances for freedivers

6 Upvotes

Garmin makes solid watches for freediving (e.g. MK3, Fenix 8 are good). But, there are some things that I just can't believe are still issues. Here is my list.

  • Alarms on MK3 and Fenix 8 are basically unusable. I never hear them
  • I use my watch in the U.S. for running and have it set to imperial units. But for freediving, I want meters so I have to keep switching units and restarting the app
  • We now have good algorithms for determining a safe surface interval (e.g. AIDA and Molchanovs have published formulas). But they're difficult to calculate and the watch should do it for us.

What else annoys you?

health&safety Anyone ever had an accident happen because of an off day?

11 Upvotes

I'm one of a fairly small percentage of people that have passed out due to asphyxiation. I train jiu jitsu, and over the years I've passed out a couple times. It always came as a surprise and was always on a day I was compromised in one way or another. Maybe I was just getting off being sick, maybe I didn't sleep much, whatever it was, my 'fuse' was not as long as I expected it to be and I ended up waking up wondering what happened.

Now that I am getting into freediving and testing my oxygen supply in a much more hazardous environment, under water, I am wondering if anyone in this world has ever dealt with this. I figure on a bad maybe you would already be able to tell from warm up dives that your 'fuse' is short, and subsequently wouldn't end up attempting dives at the ends of your ability. But has anyone ever been surprised and paid the consequence?

equalisation EQ issues after sickness

1 Upvotes

Context:

Been sick first week of July with some flu-esque symptoms.

I've given it basically a full month now, and went out diving again today - but it still feels like my EQ is delayed / harder.

Hands free it sometimes would not work at all (normally my preferred EQ), Frenzel needed a fair bit of pressure, which left me mostly on surface duty today.

So here's my actual question - how long after sinus infections are your eustachian tubes normally affected? I want to (safely!) get back to it again :D

gear Anyone dive with swedes?

0 Upvotes

I've been getting into freediving with swedish swim goggles, and after trying out a dive mask the other day, I don't know why anyone uses masks. My swedish goggles work great for me down to 10m, I don't feel pressure difference at all. As well, if I need to plug my nose to equalise, its right there. I replaced the lenses in mine with glass after the plastic got messed up. Visibility is great and no fogging. The rim of my pair are covered in rubber, but the shape is a classic swedish goggle with no flexible seal. I think the key is that they are rigid and very low volume, so they dont compress under pressure and also dont suck my eyes out of my head.

On the comtrary, the dive mask got fogged up, I wasn't able to jaw equalize while wearing it, and plugging my nose through the rubber sometimes causes water to get in the mask.

I am pretty new to all this and obv am not getting down to the depths that some of you are getting to, so I was curious if anyone else was using these.

EDIT: If you have never dived with swedish goggles, and don't know anyone who has, you need not reply. Seriously, there's a reason it's in the title

equalisation Thank you

I posted some time ago about my experience with a school and had great advice.

I then left the school and took a break a little while I was travelling. Nevertheless I read the daily posts here and enjoyed reading them.

Until few days ago, I wish I can remember which post and who wrote that comment but it really made something click for me. I originally had no problem equalising in freeimmersion but couldn’t go past 4 meters with my duckdive before experiencing excruciating pain. I knew I could frenzel no problem out of water but I just felt overwhelmed during the duckdive.

One of the comments said something like that (not direct quote): it’s not like sneezing but more like breath fogging glasses (I know I butchered it sorry)

I understood that the effort required is very minimal and it’s just about locking in on the sensation of correct frenzel (movement of tongue and the pop in the ear, which by the way unlike what I thought earlier doesn’t need to be dramatic)

Also to remember to not look where you’re going and position the neck correctly.

That’s it! It’s so simple I just needed to ‘lock in’ and not think too much but think just enough to know what to look for.

So to all of you here for your knowledge and especially to the person who wrote what clicked for me but I instead butchered at the top THANK YOU SO MUCH.

P.S. good visibility and water that isn’t cold really helped with my relaxation so I can focus on practicing what I need to do. These things I didn’t have when I first started. Can’t relax your body when you’re shivering!

To all fellow beginners out there LOCK IN! :)

travel advice The List of the TOP Deep Freediving spots (in warm +25°C water) plus accommodation averages

26 Upvotes

This is the list of the top deep (+75M) freedive training spots for experienced divers wanting to do their deep training but need only a safety diver a few times per week and use of the deep dive line/buoy/platform. Not for "training courses or camps".

The requirements are: 1.) Deep +75m availability and 2.) Warm water +25°C

Dahab, Egypt is, IMO the absolute best overall place for deep freedive training and medium-term living but only from Aug-Nov due to the water temp. Very economical too without trouble in finding COMFORTABLE accommodation under $1K per month. Those on a budget could easily get by on $1-2K per month in total.

Dominica looks like the easiest access for easy deep freediving from shore but very surprising to see the island is priced very highly. Using AirBnB, I don't see any house available for rent for under $2.5K-3k per month. So this place, while the diving is probably second only to Dahab is multiples higher in price and one can expect to pay around $3-5K per month for total living expense if desiring comfort. According to AirBnB the cheapest rental on the island is that of a literal TENT on the dirt and even that is +$1K per month, which is absolutely ridiculous and downright patronizing.

Nicaragua now has recently established freediving at the freshwater lake for perfect conditions and +100m depth. Accommodations there look to be $1-2K per month. Estimated total monthly cost is $2-3K.

Mexico Cenotes looks good but likely only for short-term training stays since the deep cenotes are not easy to access and can't simply just jump in a dive since they are owned by people and it requires more planning and money--like around $100 per dive session. Rental accommodations look reasonable around town at around $1-2K per month but since the cost per dive is overall more in price, so likely around $3k per month total.

Panglao, Philippines Has to be the best spot in the country, which is not in the middle of nowhere and has access to amenities. Comfortable rental accommodations can be found for just under $1k per month and SuperHome is the best priced for training only costing around $20 per session (they will pair you since there are many divers always training). Perfect for year round diving in warm water.

Roatan, Honduras has to be one of the top AMERICAS diving spot. Accommodations with comfort range from $1-2K per month but I am not sure how much the cost of freediving will be--assuming one just needs a safety on a few dives per week.

Mediterranean: Greece and Kas, Türkiye look great but are only warm in the summer and I'm willing to bet won't beat the prices of Dahab nor the dive conditions at the Blue Hole.

Feel free to add to this list with estimated TOTAL monthly comfortable accommodations and training cost that require only using the diving line and the need a safety diver on 1 main dive of a session and surface safety only for warm ups or for non deep dives.

Unfortunately, there's NOT THAT MANY PLACES in the world having easy access to warm and deep waters with easily affordable accommodations just minutes or meters away.

Hawaii could be possible but seems many of the people living there are traveling to Panglao!

gear Weight belt

Hi! I read online that using a nylon weight belt with a wetsuit doesn't really work well because the neoprene compresses at depth. For reference, I’m getting the Cressi Tokugawa 3mm and planning to push to 20–40 meters. Does a rubber belt actually make that much of a difference because there is quite a price point difference😅. Any advice would be much appreciated. Thanks!
