- The ascent is the most critical phase of any dive, pivotal in preventing decompression sickness. In recreational diving, crucial aspects of the ascent are often overlooked, with the so-called "safety stop" misleadingly treated as a mere formality. This video provides an in-depth analysis of the proper ascent technique, emphasizing that every dive is a deco dive and every stop is vital.
We delve into the nuances of team coordination, role assignment, and the correct handling methods of a DSMB, demonstrating a meticulously structured ascent from 10 meters. The importance of maintaining horizontal trim, executing planned stops with precision, and effective communication is highlighted to ensure a cautious and efficient ascent.
This comprehensive guide aims to elevate your understanding and execution of safe and controlled ascent procedures, significantly reducing the risk of decompression sickness or other complications.

Gotta give credit to the videographer too! Great work guys!
Until such time as it’s feasible for me to travel to take courses with you, I would pay money just to ask a lot of questions to clarify my understanding of various things. Your ability to provide clear, concise and accurate information is the best I’ve found on YT. There’s so much conflicting info out there when it comes to what to do, and particularly WHY. As always, thank you for another excellent video ❤
Thanks Phil. We will soon be launching an innovative new platform that you can join to and get proper coaching so keep an eye on the upcoming announcements, you gonna love it :) we are working extremely hard to finalise this project.
@@flowstatedivers that’s outstanding! Thank you for letting me know!
These videos are invaluable. I wonder if subtitles could be added reminding the viewers of the meaning behind the hand signals, not just in this video, but in subsequent videos. I think this reinforcement would add to the instructive efficiency.
good point, we will make sure we add these in the future.
@@flowstatediverscould be as simple as adding subtitles or labels positioned next to hands showing hand signals. Excellent idea IMHO
subtitles can be added to any video by clicking the closed caption button in youtube.
Perfect for a monday lunch break at work! Can't wait 🤩
Have fun!
Brilliant video as always! I can only repeat myself every time you post a new video 😆 informative, absolutely no bs, beautiful shots, exceptional quality. I just simply love your videos! Thank you for your hard work, sharing your knowledge with all of us!
Best Diving Videos ever!
This is such high quality content. 🙏🏽
i have been growing with your channel, i got ow certified in may 2023, and watched all your videos before gue fundamentals. now i'm ow, aow, deep, drysuit, gue fundamentals, razor sidemount and cavern/intro to cave. thank you and would hope to dive with you guys one day in tenerife.
Great to hear! Make sure you slow down, as the list of things you've accomplished in such a short period sounds excessive. Focus on quality because certifications only prove that you participated in a course once, nothing more. Make sure you dig deep and become a solid diver with all the fundamentals of diving. Seek out the best instructors and enjoy the new things you have learned.
@@flowstatedivers Yes, I intend to slow down now. Even though I have good trim/buoyancy and can do all the required drills and skills, I don't plan to take another course until I rack up another 100 dives (not to mention countless pool training sessions) and can switch seamlessly between twinset and sidemount. I seek out the best instructors in the regions where I travel, except for my OW, when I didn’t know what I was doing.
I was never interested in marine life, so I wanted to dive in caves to justify my diving. I finally managed to see the caves in Tulum after my certification in March. So, no more course chasing for me.
On a side note, are you using the UTD Z manifold for sidemount diving? If yes, why do you choose that over a conventional sidemount rig?
I love these videos. as a new diver with only 40 dives I find this infomation and tips super valuble. Thank you so much. P.S your video on releasing a DSMB actually allowed me to perform a correct deployment for once without issue 2 days ago :P I was so happy.
Awesome, thank you!
Thank you very much for the knowledge it will be put to good use, once again Thank you for all you have done
Thanks for tuning in, glad you like them and I'm sure it will improve your diving if you put the required work in :)
This goes to show how crappy training is with certain agencies is. I have 160+ in over a year and I constantly learn more from this channel than from the instructors I’ve had 🫢 Back to when I did my AOW I wasn’t even thought to use a dsmb. I had to go online and watch a bunch of tutorials but it’s messed up that they’d allow someone who doesn’t know how to do something so important pass an “advanced” certification 💀 Thank you for sharing your knowledge 👏🏽
That sums up the reality of today's dive industry pretty well. Divers like you will make a difference, so keep an open mind and put in the time to learn and spread the word. Thanks for being part of the movement!
These videos are absolutely amazing. They're clear and concise, but still offer rationale and invaluable "pearls of wisdom." Moreover, they show that the goal is being perfect in best practices.
I investigated your website, and saw that you offer both PADI and UTD courses--that's a good example about why PADI's new five star dive center initiative (in which instructor are not allowed to offer non-PADI courses) is so misguided and potentially harmful. If the videos are any indication, you guys operate at such a higher level in terms of your training standards that it really does students a disservice by not letting you guys be "the best PADI has to offer" because you give students an alternative that is so much better.
Thank you very much for the kind words. We have always maintained that training organizations are secondary to instructors. We deliver training that far exceeds any standard requirements and are able to sign our students off under different organizations, not that it matters. Everyone at FlowState comes from a cave & technical diving background, and we are here to deliver exceptional service. Who knows... soon you might be able to sign up for an actual FlowState Divers course ;)
New diver loving the Chanel, really helping 👍
Thanks and we are glad to hear that new' divers are also interested :)
Ребята Вы молодцы, отличные видео, все очень точно и красиво реализовано. Спасибо, продолжайте, буду совершенствовать свою технику с вашей помощью!
"every dive is a decompression dive" - so true...
your the best guys .Great work 👌👌👏
Awesome once again! Really interesting to see that this can be executed with such precision and control. I'm sure that everyone will take away something from this video.. once again!
Glad you enjoyed it!
BRING IT ON!!!!
You make really brilliant videos. We use all the hand signals in exactly the same way because they also work with thick drygloves. As a three-star CMAS diver, you often hear that our training is outdated and far too strict. In my opinion, alternate breathing is also important. Not because it is very likely to happen, but because it clearly shows you how and whether you know your equipment and have it under control. That's why it's so exciting to see that there are also divers "overseas" who teach exactly the same thing (from what I've seen in the videos so far).
Really great videos 👍 thank you
Thanks. CMAS undoubtedly has some really good old-school style elements in their general curriculum (and some less great ones), but hey, incorporating the best from different things will result in something good in the end. Thanks for the kind words.
I always did my ascents from the safety stop to the surface vertically, I tried your method during my dive last Friday.
I must say it felt very good and a more professional way to do it 💪.
Great to hear you had success with it !
Great video again! Guess I'll just have to plan more dives now to practice... 😂
This is awesomeness, guys.. chapeau! 👌
As always, super informative content, great demonstration!
Thanks!👌
Thanks, glad you enjoyed it
Just amazing videos from you guys!!
Thank you, appreciate it!
Very nice video. Thanks.
Regarding you comment about being vertical during ascent. I read that research showed decompression is still quite effective. That said, horizontal is definitely the preferred orientation. It slows down your ascent too.
We exaggerate some statements on purpose in hopes of having a larger impact on divers (those divers that are in complete denial), encouraging them to do the right thing rather than neglecting the facts we share. Of course, you will off-gas in any position as you ascend, but it is less efficient than being horizontal, and these two techniques cannot be compared.
Awesome Content!🎉
Thanks !
Great video as always
Thanks Ian, glad you liked it
@@flowstatedivers all you videos are top class
Do you have a link to the research paper which demonstrates off gassing changes according to orientation. The pressure differential of the average diver at 175cm ina vertical position is 8% of 1 atmosphere or 1.6 inches of air pressure. The largest physiological factors which affect off gassing are respiratory physiology, body fat composition, cardiac output and hydration status.
Gases evolve from tissues according to Henry's Law according to the pressure of the gas over the solution. So having an 8% pressure differential between your eyes and your toes is really 4/5 of diddly squat.
External factors are far more important to teach a student- rate of pressure change ( rate of ascent), gas mix ratios ( why do we not teach Nitrox in entry level courses) and total time at depth (gas absorption) .
Otherwise a good video.
Alright, I have a question related to DSMB … in my early days of recreational scuba diving, my instructor trained us deploying DSMB - of course not the oral inflation type; we were at the depth of 5m doing the safety stop (haha :D) and I deployed one. When we surfaced, my instructor commented that my DSMB was not fully inflated, I should add more air next time. Question: how much air is needed for a “successful” deploy? Thanks.
Thanks for your question; it really is a good one. This all depends on the surface conditions, the width of the DSMB, and the depth from which you are deploying it. Obviously, the deeper you deploy yours, the less gas you need to add, as it will expand on ascent. It's a common misconception that you have to have your DSMB fully inflated. One of the reasons why divers are so hung up on this is because most believe that a DSMB will only stand up straight on the surface when it has 'enough gas' in it. In reality, any SMB will stand up straight if ample pressure is applied from below, so it really comes down to surface conditions in the end. In the video, we were diving from the shore in approximately 20 cm waves, which means having our DSMB sticking up about 30-40 cm was perfectly fine. What divers usually forget is that you can fully inflate an SMB if needed after reaching the surface and it takes anywhere from 3-10 seconds.
@@flowstatedivers wow ~~ you blown my mind with your answer and explanation, I really learned from you. Thank you very much!
Great video, but I didn't notice the divers adjusting their bcd / wing while ascending. Was that just not included in the footage? I figured if you didn't release gas from your bcd as you ascend, you'd start an uncontrolled ascent.
It's discussed in the comments below. The reason the diver's not adjusting their bc is because we dive correctly weighted and therefore, we finish the dive with 0 gas in our wing / drysuit, which means there's no gas to release. Check our video on correct weighting and breathing techniques to understand the concept.
Is the diver only using his lungs to accend? I see he doesn't touch his wing inflator in the video.
@johnmaxwell1434 Correct... this is how you should be diving, correctly weighted. Have a look at our correct weighting as this is all explained there in details.
I think a quick video on DSMB selection is probably required. A lot of peope use open bottom ones and they are filling them with their second stages. They're risking getting a very full DSMB caught in all the silly straps these come with and in their line.
I rarely dive anywhere with so little current that holding a circular formation is possible. The best that can be done is a stretched out horse shoe because good luck backfinning into the current for minutes at a time.
Our very first video covers just that, explaining the difference between DSMBs. Also, we are seriously puzzled by comments about diving in currents. First of all, ascending in a current makes no difference whatsoever, as holding position relative to your team is no different than in calm water, since everyone would be drifting the same way. If you are referring to a surge, it's trickier but absolutely doable.
@@flowstatedivers sometimes an exit point is fixed, so unless you want to surface swim after drifting off the mark... Sure, you could take a guess at how far you may drift during ascent but in my experience nature often as other plans.
@harambeexpress you either properly drift diving and are being picked up by the boat upon surfacing, or you simply shoukd not dive in current unless you have a DPV. It's that simple in our book
@@flowstatedivers I understand what you're saying, but as an example I don't think a shore dives which can be done as a drift dives are unreasonable. You just have to adapt and avoid certain scenarios. Getting a large deco obligation on one or these dives is certainly not on the cards because the environment is too unstable.
However for dives within recreational limits It just means you do things like gradually shallowing up towards the end of the dive inorder to minimise your final stop time dealing with current. You can also get quite a nice profile doing this. It might also mean that you operate in pairs for the final ascent rather than a full team, because in pairs you can be next to each other and still have good communication and proximity for dealing with issues. Flexibility is an important skill to have.
@@flowstatediversI think they’re referring to an ascent along an anchor line or buoy in a slight current. Pretty common situation in my experience.
Pero quiénes sois, y qué pedazo de videos.
