I only have 4 dives under my belt as an OW diver and a refresher course but I definitely must say watching all of these makes me way more confident. I am heading to Cancun to dive this weekend and now I really can't wait.

Excellent lesson !

It had been quite a few years since I dived. Were in the Dominican Republic last week. My 17 yr old daughter had her first open water dive. She was great. I’m usually a bit stressed the first few minutes. The dive master was chewing me out with hand signals to get more parallel and use breathing for buoyancy and not the BCD so much. I eventually got the hang of it. He even clapped underwater eventually. Your video was excellent. I really enjoyed the 2 nd dive and used breathing for the neutral buoyancy joist of things. Excited to do more of it. Thanks, Sam

Love your videos!! Always informative.

2:20 "by adding air to your BCD/dry suit, you are creating more volume, displacing more water, displacing more weight of water, increasing the upward force" I had not thought or understood of it that way. The true explanation. Thanks!

Same, this makes me feel much more prepared for my advanced open water course. I don’t feel ready after just open water. Getting my own BCD with integrated weight packs is even more important since I never felt right wearing weight belt.

You are a brilliant teacher. Clear and calm. I wish you’d taught me! I’ve learnt so much from your videos and am looking forward to putting it all into practice on my next dive holiday. Thanks 😁

Same here 😊

Just another additional tip for those who still try to find out their neutral bouyancy. When I teach people I let them stand on their right hand, trying to be horizontal hovering. So they can feel the pressure of their weight or their down force on their right hand. They can feel the difference between inhaling and exhaling. Now they put air into their BCD and they have a feedback on the change. So they usually can estimate when neutral buoyancy is achieved than by laying on the ground or ascending towards the surface. Next step is doing the same with just a finger. So they usually can hover their finger a centimeter above the ground within minutes. I never sold a Perfect Buoyancy course to any of my OWD students so far. ;-)

Thanks, very helpful

This is my favorite scuba channel, your explanations are excellent.

Great vid. Im going to have my OW training in a week. This vid helps a lot. 😊

Wow. As a recently qualified open water diver (12 months ) I thought I was reasonably competent. This is the back to basics that every diver ,new or old should learn . I think that knowing the "why" is just as important as knowing the "how"" . like many people watching this serious of video by you I wish that this was part of my training.

very helpfull for me as a newly certified owd with 8 dives and two try dives in total.

Amazing tips !

such a great resource. i find it very hard to control buoyancy in the top 10m due to the percentage of volume change. will definitely have to try these exercises when i can access some water(has been 3 years). very much appreciate these videos. keep up the great work.

It is interesting to watch the videos of Jacques Cousteau , he managed to dive not using BCD.

Amazing video! It's so great that you share your love for the ocean. Scuba diving is such an amazing water activity and it's lovely to see you enjoy it, keep going with these great videos. If it doesn't bother you, I'd like to give you a suggestion, a tip for the next videos: Basically, you could try inserting some comic and funny stuff... to give everyone a pinch of humor that, in the world of diving, can never be missing. Now, I don't think much of it, but the first thing I could think of in your sport might be peeing in the water. Once, my uncle, who is a scuba diver, peed in his wetsuit during a long diving session and that moment was absolutely funny, he even wrote "I’m peeing" on a waterproof notebook during the session. He has always been telling me that there are 2 types of divers and swimmers: those who pee in the water and those who lie. I know it may sound strange as a request but, in my opinion, these are moments of happiness and carefree that always make everyone smile. I hope you like the idea and I hope you have a wonderful day!

excellent video. showing buoyancy in a swallow pool is incredibly hard for the drastic change in water pressure in first few feet of water just one small thing on part 6, as we go deeper, the downward force ie gravity does not change a lot. Instead the water pressure causes air in BCD become smaller and we compensate the decreased volume back into the volume we need to balance out gravity by adding air into BCD. but the execution is the same

@everythingscuba

Жыл бұрын

Thanks for your kind words. Gravity may not change but certainly water (ambient) pressure does change. We add 1 atm of pressure for every 10m/33ft of descent. I do agree that compression of gear increases thus the need for additional bcd volume to balance out that additional pressure. Thanks for your comment and thanks for watching!

Love the videos Lyell. I have a question, however. You mention using the BC or Drysuit as your source of buoyancy. There is an argument that you should never put more air in dry suit than necessary to stop suit squeeze. Others teach you to use the suit as your buoyancy compensation only put air in the bc to keep you on the surface. What are the arguments both ways?

@everythingscuba

Жыл бұрын

Michael you are correct some divers primarily use their dry suit for buoyancy and some merely inflate their suit to avoid a squeeze and then adjust further using their bcd. I personally only use my dry suit once my bcd is fully deflated. But in either case the principle still holds that using either method effectively increases the volume/weight of water being displaced thus increasing buoyant upward force on that diver. It somewhat boils down to personal preference and training as to which method a diver uses. I’m not sure it makes a huge difference either way.

I am finshing my Advanced Open Water Cert tonight. My neutral buoyancy is fine horizontal. While doing a vertical, my body tends yo fall backwards and I struggle to nlbring it back without 1 kick.

This was a great video and you explained really well how we can improve our buoyancy. My only issue is with the hovering. I always dive with full body 5mm suit and I cannot stay in an horizontal position because my fins stay at the bottom. Is it possible that i should change my suit or fins or i should just practice my breathing more?

Great video. Thanks. I am a recreational diver. Very few warm water dives a year. I went to a pool to focus on buoyancy and found that I was too distracted because I was always moving. I could not stop myself from drifting. I tried focusing on not moving at all. It did not work. Is this something that also takes time and practice?

Practice practice practice Albert. And yea it can take some time to get yourself stable. Working on that core strength also to maintain upper body stability is a good thing! Thanks for watching and thanks for your comments!

they tell you Never hold your breath while diving, but when I'm doing precise, fine buoyancy control sometimes I'm holding my breath or keeping my lungs partially inflated without completely exhaling. And when you're holding it you're obviously going to ascend. That's why you're holding it, to go up. I always knew that was a contradiction. Instead of adding and dumping tiny amounts of air with the bcd, you're using your lungs.. It feels like flying a balloon and you're the balloon. I guess if you're good at it you don't over expand your lungs. even just controlled slow breathing is holding it before exhale. I always think about that while I'm diving.

I feel like my buoyancy and my trim is right and I can maintain my 15’ deco stop but I have trouble at the deco stop standing vertical. It seems like I loose my balance. Any tips?

Nothing has happened to it. It has not been released yet. It will be soon.

I need some advice. Imo I've got good buoyancy control and trim. I've never felt a need to use my arms and I hover fine in any position - vert, horizontal, head down, on my back or side. I keep my back slightly arched, arms relaxed in front of me, and my knees bent when I don't kick. Everything feels great - as long as I'm moving. If I stop finning and just relax my legs will slowly but surely sink and I'll find myself in a semi vertical position no matter my body position. I've tried putting a weight on my tank strap and it helped somewhat but I still find myself fluttering and not quite fully relaxed. It should be noted I've only used jacket style BCDs and not tried a bpw setup yet. Still, I don't want to have to rely on a piece of equipment to maintain a good relaxed position in the water. All advice appreciated!

Carl - I’d say that falls more into the concept of “center of gravity” versus “buoyancy control”. I had this issue as well. If you think about how much weight you have above your belly button (rough approximation of the center of your body) compared to below your belly button that would give a sense of opportunities to fix. I’m not sure of your exact bcd setup, but if you have integrated weights - you likely have all of your weight below or at your belly button making you feet heavy. For me, I had to switch out of my super heavy negative fins to lighter positive fins. I then added a couple pounds to my top tank strap. It evened me out almost perfectly

@everythingscuba

Жыл бұрын

Carl I would agree with B. Are your fins negatively buoyant? If so switching out to more neutrally buoyant or even positively buoyant find may help you out! But in addition I’d makes sure to have some trim weights potentially on my tank strap to balance out your weight distribution.

You can use your arms and legs as a balance. If you tip forward, draw your arms toward your body and extend legs. Reverse if you have "heavy" feet. Push your arms forward like Superman and place legs 90 degrees up.

Buoyancy should be done from the top down.

This comment is not going to be received well by the vast majority of divers and I do apologize for that in advance. This is not a good video for perfect buoyancy. First, fin pivots are not perfected neutrally buoyant. They are performed slightly negatively buoyant and foot heavy. One of the problems of how buoyancy/diving is taught today is that center of mass and center of volume (or displacement) results in a diver going vertical. Weight distribution is critically important to ensure that a diver can hover effortlessly without hand or fin sculling. Unfortunately, the rebreather diver shown here is foot heavy as shown by the sculling. Center of mass and center of volume/displacement are critical concepts that need to be understood by new divers. When it comes to starting CW1 neutrally buoyant and trimmed, a better approach is to have students lay face down at the surface. Slowly hand them weights until they sink sufficiently to rise and fall with their breath in the water column. As weights are added, distribute weight appropriately to maintain the horizontal position effortlessly. Trim pockets on the cylinder straps are an ideal location. As people tend to be naturally foot heavy which is exacerbated by shorty wetsuits, it may even be necessary to add trim pockets in a cylinder strap not attached to the BCD but at the top of the cylinder to address this. This method is sometimes needed for less expensive BCDs that only have one cylinder strap. Weight distribution is key for buoyancy.

A fin pivot is not a method to become “perfectly neutrally” buoyant but to allow students to begin to practice their use of breath control to alter their position in the water column. Your method is an interesting alternative….I have never seen any agency teach in this method. Lastly, we fully agree that weight distribution and center of gravity is critical and we did address this in our previous video about achieving good trim. kzread.info/dash/bejne/eGmupsOdc9LAgrA.html Thank you for your comments and thanks for watching!

@@everythingscuba sorry, I haven't seen your previous video before commented as this one was sent to me. I did look at the link of your previous video and I didn't see anything concerning the difference between center of mass versus center of displacement/volume. At what time do you discuss it as I watched it twice (but at 2x). Nor did I see discussion on the varying density of the human body as this affects trim. Nor did I see the difference in using a BCD versus dry suit for buoyancy and its affect on trim (when teaching dry suit, I have students compare the impact on trim a BCD and dry suit being inflated has on their trim). I'm not a RAID instructor, but you may want to look at their instructor guide information. It is very good and they provide similar techniques to my own. The traditional techniques after the invention of the BCD and when PADI started the "we put you on scuba before anybody else" resulted in poor buoyancy techniques being taught. I hestitate to say that as it can easily lead to a fight. Not trying to be an ass.

Actually when I was a PADI IDC Staff instructor years ago, I had a long discussion with my region's training rep who had my technique above discussed in a staff meeting. As i was starting from the surface, i was not violating standards. I know a number of the PADI dive pros who wrote the article "Moving to Neutral Buoyancy" that was published in 2011. (I recommend others reading this exchange to Google it as it is a available in PDF form). Several of the authors helped me teach neutrally buoyant and trimmed. The primary author of the article has been teaching fully neutrally buoyant and trimmed. He also has a cave background. I have had the fortune of having several mentors from multiple agencies with revresthers/cave backgrounds help me. Nothing of what I said to you I invented. For the sake of others reading this, nothing I am discussing do I deserve credit. Not. A. Thing. I do appreciate this exchange and your integrity to converse with me. While I do appreciate the time limitation due to short attention spans (as I often watch videos at 1.5x speed myself), but you did make several analogies regarding course/fine buoyancy control using the BCD/lungs. I personally don't think that was necessary. Finally, fin pivots are detrimental for achieving neutral buoyancy due to the foot heaviness (however so slight). One of the things I observed when I was in Belize last February was divers using half of their finning to become horizontal. Finning masks buoyancy issues. In full disclosure, one of my mentors sent me your video as a bad example on buoyancy. He may very well be the best open water instructor worldwide as he understands body mechanics like no one else. While I am an instructor, I will not certify my own daughter, but travel cross country to him to train her while I dive with his business partner.
