There's a major flaw in this video. I strongly believe that every diver should carry a surface marker. You can use it as an emergency BCD. It may not have the same volume, but still. Also, a common mistake from divers when using such a device is to use their reg to inflate it. Why? why waste that precious O2 you need? Instead, use your exhalation to inflate it. It's air you're going to ditch anyways so why not "recycle" it and keep your O2 in the tank.

Because chances are if you're using your smb then you're about to ascend and should have plenty of "air" not "O2" left. There are also plenty of diving environments where an SMB isn't really necessary.

Add a D-ring to your weight belt. Clipping your DSMB line to the ring before ditching allows you to reel off the dropped belt in a controlled manner. You can also recover the belt later by just reeling it in.

You started the video stating that being overweighted would be a serious problem and could leave you stuck on the bottom, but then you didn't demonstrate this in your example. Even over weighted by 2-3 kilos you would still be able to swim to the surface, and with integrated weight pouches could even drop one pouch to assist with the ascent in a safe manner. With time, you could even remove a single weight from your belt to compensate for the pressure. You mentioned it is dangerous for misinformation to be spread, but it seems sensationalized to state serious issues, and then not show why it is, or explain that very well.

My thoughts exactly.I had more issues being underweight than overweight. A couple of times couldn't stay at 5m safety stop with BCD fully deflated and completely exhaling. I agree with his point about the weight belt, though. Dropping the whole belt is dangerous and removing individual weights is not practical in an emergency. Especially if the bottom is not near and you are dropping to a dangerous depth. Integrated weights are the way to go.

Buoyancy is super critical?! Like up and down in an elevator or stop and go in a car. Either you learn to inflate and deflate your BC and figure out your proper weight belt (you won't sink with too little weight), then you shouldn't be scuba diving or driving a car. Is learning to breath super critical too?! LOL. Common sense, and if you don't have it - Darwin is waiting for you. What is super critical, you ask?! Not rushing to the surface fast (the bends), diving the deepest first and not last (run out of air), and stay calm in an emergency and work with your buddy to solve it rather than panic and drown both of you. Now, that is critical. Learn the basics, put your mask on and off under water, be calm, learn to buddy breath, plan your dive, and don't panic. Buoyancy should not be super critical. LOL.

As a divemaster (working or just recreational), I always take 3-5lbs more weight. Sooo many times there is someone who doesn't have enough weight and will start floating up towards the end of a dive. So, yeah, if you are with seasoned divers, go perfect weighted for yourself, going with beginners, add some to keep your random partner from fighting the float and get more bottom time.

As a beginner, how should I be correctly weighting? I use an app called “Buoyancy Calc” on iPhone. For me in a 3mm long with AL80 in fresh water at 175lbs it says 9.5lbs. I did experiment and took 8 for one dive and I felt like I was fighting as I got lower on air. 10 did feel heavy but I also am not good at buoyancy control and I know 10 did hold me down the whole dive and I didn’t feel like I was fanning myself down close to the end. I was taught that with ur weight at the beginning of ur dive you should float with a deep breath and then seen to about eye level with the water as you exhale

If you took a diving lesson, you'd know that the fastest one can ascend during an emergency ascent is the speed of your bubbles which is the speed of an uncontrollable ascent would be (assuming no panic kicking up). As long as you are not suppose to do decompression (advanced diving), if your tank failed, you swim up with your bubbles and exhale say at 99 feet or 3 PSI, you lungs inflate 3 times as you swim up to 1PSI at surface... then again take an entire course on scuba to learn the physics and proper training.

You're neutral buoyancy rocks, I took my OWD and my buoyancy sucks, need to practise a lot to control, neutral/positive/negative, I struggle with the weights, because I tend to change a lot on my wetsuit. sometimes I just use the bcd on top of my skin, others, I have just a simple jacket of 3 mm and others a full wetsuit of 5.5 mm, of course when I dive "naked" without any wetsuit most of my problems with weights disappear, but it's tough to control the belt.. and it hurts. Thank you for your clean explanation, will measure and take action on my weights.

Control his flotability (your weight) is absolutely the best way to dive safely (and instructions there is perfect), not only in case of failure, but also for better dive experience, better breath, better resistance to cold and current. Let me add that get your weight on a belt (an elastic kind of "marseillaise" belt) is also a best way to hold added required weight (if need), not only because you will have this weight close to your G point body, but also in case of scaphander "quit" to go in a little hole or any other reason you have to experience it. As a commercial diver, i can not pretend to practice so much this kind of best technic at work depend of the job to do (sometimes we have 40 extend Kg to stay stable on a rope to be able to weld in wave conditions in shallow water... the helmet is also heavy and more weight can be more power to work on seabed for rock destruction or any other works that require human power to be efficient, but if we can dive with "tourist" scaphander (or sometimes with rebreather to stay long time or deeper) for long range inspection (2000m long to go between 20m to 70m depth with a camera, for exemple), we always choose to be perfectly equilibrate underwater in reference to the decompression higher point with empty tanks (we are using double steel tank 10 or 12L without jaket, but aluminium if rebreather for safety tanks). When you can do it, best flotability will make your life way better and you consume of gas as low as you can too, increase your decompression point the safest way. Do not hesitate to experience things in shallow water as a game with weights before to experiment something deeper... shallow water is always more difficult technicaly for flotability management, but the best school before to go deeper, because you will have low time to no time to thinking under 50m depth (and you will thinking wrong most of the time due to narcoleptic reasons). The best school by experience to learn to control and share good experiences, best practices from other "old" divers is cave diving school (better than commercial diver for technical points, most of the time). Stay safe, don't go to search record but enjoy elements, sensations and underwater life and reliefs (or wreck). Stick the timing, check material closer, be clean with yourself and be quiet in all conditions will help you to be lucky sometime.

excellent technic to use outlet air to create a buoy. You first have to learn to do it perfectly to be able to do it in special time when you will NEED it. For the little story time, an old friend (dead now, in his bed...) and very old diver who used to dive to search corals (his job) was using this technic and had a perfect control of his weight at any depth. When tank was going to be close to empty, his old regulator started to be strong,... it was time for him to outlet air in his bag and hook the corals, then thinking to go up... little by little, air going to be very strong in his regulator and time to left the 120m depth along the safety line... little by little, during the way up, air was going to coming back again in the regulator, due to old regulator technology that let air come again when ambiant pressure reduce (first and second stage without compensation... the best for strong material and zero surprise experience), just enough to go to recover oxygen bottle (i can not tell you how deep it was, it is not something you can do normaly). He used to dive like that during 50 years and was one of the oldest diver to still dive (he also notice by feeling when he can go upper or not at decompression time: zero accident)... This old guy was incredible and used to go so deep to work with so less air in his back (i never see again someon euse so less air to dive) ! Just because he was very quiet and control perfectly his flotability (and because of this "recover buoy bag"). Used to dive every day (only one dive a day) !

This is great theory to know and it's something people should strive towards, however as with everything, reality is a little different. I can get to perfect buoyancy with a single for my rec dives, but with doubles..... no way. Dual HP100's full is -17lbs and that's before accounting for manifold/regs and all the other gear. I've even bought a carbon fiber backplate to reduce weight as much as possible. My doubles wing is a dual bladder for redundancy. In much the same way as in theoretically electronics (computers) also rarely if ever fail and yet I take a second Perdix AI, just in case the primary fails. Theory vs. reality.

Reality is if your BCD fails, you use one of your SMBs for lift, or you use your alternate to blow up your wetsuit, or your drysuite if you dive with one. And belive me, if you have to, you will kick that out, plenty of lift can be created with your fins + weigth drop.

I have had two BCD incidents in the last few Dives. One was a power inflator that was leaking so my BC was filling slowly during the dive. The Simple Solution to that was to disconnect the power inflator and use it the old fashioned way. The second incident I had the power inflator hose somehow got loose where it connects to the BC itself on the shoulder. Neither incident really was much to write home about I dealt with it I signaled my partner that I had a problem and return to the boat no fuss no muss. When I got to the boat I examined the connection and tightened it up. No life-threatening situation just deal with it.

Warm water divers might find themselves surprised if they go diving in cold water with the necessarily thicker wetsuit. The more foam neoprene the diver wears, the more buoyancy will be lost during the descent. That can make it more difficult or impossible to swim up from depth without ditching weight.

I agree with the premise of not dropping weights to get to the surface. I'm not an instructor and here to learn, but it seems to me that dropping weights is more for gaining positive buoyancy after reaching the surface than for getting to the surface. If there is an emergency and BCD has failed, I'd get to the surface and then ditch weights to help stay there. No?

Just don’t dive alone. That way if your BCD fails you just hold on to your dive buddy.

Would love to hear why double bladder is a bad idea???? Agree with being correctly weighted but also I feel like you are either diving in a 3 or maybe 5mm wetsuit. 7mm wetsuit or semidry buoyancy loss at 30m might be a bit different i think...

I learned this the hard way. Back in 2003 I was 30 and decided to learned to dive. I have lived on the Gulf of Mexico all my life salty water gives me the feeling of being home. So I started going to a very popular dive school in Jacksonville FL. I passed everything did all my check out dives. For my first open water real dive we decided to go to west palm beach and do the shark bowl. After spending 30 min at 80ft it was time to go. I reached over to bump a little air back in my bcd and nothing happened. So I stood up and got the attention of my dive buddie. I was at 1000 psi and had a 5 min safety stop at 15 ft. So I dropped my led bags out of my bcd and I was still standing on the bottom looking a black tips coming in to check out my problem. I put my octopus in my wetsuit to make a redneck BCD. It only took a few short bumps to get me neutral.

If you were trained properly (OW divers aren't permitted to dive to that depth) you would have known that a couple of breaths into the oral inflation valve would have made you positive enough to make a controlled ascent whilst leaving your weighting intact and without comprimising your remaining gas or alternate air source. It's lucky you didnt suffer from DCI. Any other new divers reading this, please know never to do this. It's both stupid and reckless. We are trained correctly to know what to do in these situations and this is not it.

I have been diving since before BCDs were around. There weren't any underwater pressure gauges either. The most important lessons that I have learned are: learn to control your breathing so that you never exhale more than half your lung capacity; never dive below 60 feet without a pony bottle.

Hi have you ever seen somebody dives with carbon fiber aluminum cilinders? I received a buoyancy table from carbondive, Austria and I'm thinking about to dive with this tuxing 6.8L China cilinder. We dive maximum 15 m. Normally 5 to 10

why do we need weight belts then? why not put the weight inside the bcd. atleast you mention the wetsuit, this is a huge part of neutral buoyancy. im sorry but i don't agree with you.. being able to emergency ascend is better than not being able to.. As an ex military diver we didn't even use a bcd.. buoyancy was found with the mm of the wetsuit and then knowing what depth you would be working at and then experience to know what weights you need.

Went through OW and never even talked about weights. How does one learn this stuff?

I assume the point of this video is come back up without ditching your weights if the BCD fails. Versus the point of no return and having to dump your weights? In the end you're not going to get much lighter than dumping your weights so it doesn't matter if you're overweighted by 100%. It does matter if you want to keep your weights...
