DSMB deployment by Garry Dallas. RAID UK & Malta - "Ask Garry"

- In a 15m depth swimming pool (Durktank, Belgium) hovering in very shallow water, 2.7m practicing skills will make any deeper dive DSMB deployment much easier. It's all about transfer of buoyancy.
So many issues happen during DSBM deployment, most divers defer to their more competent buddy to deploy one. Competence can only happen when you practice.
The idea here is just to prove that DSMB deployment can be done safely. Where the pressure difference in 2.7m has the most affect on a diver's buoyancy whilst filling a bag.
At depth, the skill works far more easier and therefore less risk of problems.
Do it safe and slow.
It is not a demonstration video, just a guide but it works very well. "Garry's tips"

Fantastic. I really like the middlefinger gesture ;-)
Awesome video. Seriously impressed by your buoyancy skills.
Thank you, very kind of you!
I feel like the baby turtle in the GIF meme. Probably because I am. :)
I'm still watching this again and again after all these years to adopt every little aspect for myself, and you're still the best I've ever seen Gaz.... Really well done👏
That’s incredibly kind of you to say, thank you 😊
You're boyance control is a work of art. I aspire to get that good! Cheers from the USA
Signalsoldier thanks! Some people call diving a sport.... as you say it’s art 👏 where are you from in USA?

It's going to be a while before I can get that proficient at buoyancy and trim. Strong. Work.
Kenneth good training and practice on good skill sets, it will all come together:-)
Kenneth ... you know I have to say, I do hear people say this a lot. I teach this in one or two days.... this level of skill is easily achieved. Ask any of my students. 😊
I’m watching this over and over - brilliant demonstration, small tips like adding a tiny bit of air just to make it manageable make the whole process so much easier - although how you do it maintaining perfect trim god only knows. Awesome.
Thank you! Partly moving the gas around to be effective and not a problem, the lack of stress because I have time and the practice of course :-) enjoy!!
Yes that was a great tip to do before the launch. Remember that a small breath into an smb at your depth will not change your bouyancy at all. The breath you take in after will only slightly affect it.
Sir.. What you explained without even a single word.. My instructor was not able to explain in 1000
Hats off to tour buoyancy skills..
Felicitaciones, muy grafica y clara tu demostración!!!
👏👏👏👏
Thank you Gary, I learnt something today from this
I just found out that this video is just so superb that i have to take a look at it like every month and it still has the same wow effect. I admire your skills and hope that one day i will take a course with you as instructor.
tarzan1163 thank you so much for your comments. That’s very nice to hear it inspires you. Yes maybe we will meet one day even just for a fun dive 😊
Great demo!
Wow, what extremely clear, step by step instructions, thank you.
Hi and thank you 😊 although it’s not really intended as a precisely instructional video, it is fairly easy to see how it’s done. Enjoy!! 🤙
Incredible, I've never learned this method but it's the best I've seen. Plus, your trim!!! WOW!
Thank you!
Trim is one thing to keep constant, but the deployment act is all about safety and time. Time to observe and not just react to too much buoyancy. if you notice, I dump gas from the dry suit as I blow into the back. This counteracst the positive buoyancy
Great vid Garry. More please!!!
Gary Anderson I will as I have the time. :-)
Great video! I hold my smb right hand while inflating in order that I have my left hand available for correcting buoyancy if needed.
Konstantinos Bakopanos that’s absolutely
fine using wing for buoyancy then holding regulator in hand while inflating dsmb.
Thank you! Still a fairly new diver, almost 50 dives, going out this weekend to get some practice at my local dive site and am planning to do some dsmb deployments on all my safety stops. Was scratching my head trying to pre figure how I'm gonna do it and seeing your vid with the line already attached to the smb sort of put in all place for me! So simple yet I didn't think of it before! Thanks again, safe diving!
loobie doobie you’re very welcome! Loads more tricks where that came from. 😉😊
loobie doobie that’s for watching and your kind words! Safe diving and enjoy!! 😊😊
loobie doobie it’s a simple understanding of weights and balance.
Great as always Garry. Probably my favorite way of deploying an SMB of all the videos I've watched so far. My dive buddies keep getting offended when I give them the middle finger like you did at 1:24 , but I tell them it's part of the procedure.
Love it Christian haha... keep it up ;-)
Great work Gary, effortless
Thanks Christopher!
Thank you, Gary, for this very well demonstrated video. I have been scratching my head for a while, wondering why 90% of the videos I have seen show the reel and DSMB carried separately. This has made no sense to me.
I am thrilled to see that someone else carries both together as well.
Thanks again for the video.
Dive safe.
Those videos have the spool & DSMB separate likely because part of the skill requires them to be put together - Slight task loading with an emphasis on the diver maintaining trim, position and situational awareness.
For all practical diving purposes they're attached.
Very nice Garry.
I love that roll to the right to let air out of the dry suit to maintain buoyancy.
That’s the key to maintaining correct buoyancy and depth as you breathe in air for the DSMB 😉
@@Garry_Dallas What do you do on a wetsuit though? Free up one hand and let air out of the wing?
Cheers Gary, I figured it out from the video. Savage stuff. Very secure in both a pocket or clipped to an external D Ring.
Neil Egerton probably still need to do the video though as it highlights a couple of tiny little points that makes a huge difference
Definitely would like to see a video of the fine details. Of all the smb videos I've seen on UA-cam, so far I like yours the best.
Garry Dallas I’d love to see that video on your spool/dsmb preconnection.
Right what i was looking for. Sometimes a pre-rigged dsmb just is nice! (Lot's of divers on deco, ruff sea, etc....) Just shoot and hang! No need for the extra fiddling with mounting it together. (diving thick dry gloves)
Split-Photography thankyou :-) glad you like it :-)
Amazing buoyancy 😍
Thank you.. Made easy by finding what really works to achieve perfect balance with every breath. Self taught 😉
Just deployed my DSMB last week, what a f*cking nightmare! I felt very uncoordinated trying to get my reel, find my DMSB in my pocket. Neither were clipped together and it looked like a new diver trying to deploy a buoy. Buoyancy control? LOL...no, none at all. After watching this video, I am making a few changes and will practice this when I go diving to feel more comfortable with it. Garry makes it look to easy and effortless, which is what it should be. Thanks for the video!
So sorry for the very long delay in replying, maybe I had lost internet when replying.
I hear you pain... neutral buoyancy is everything , but also the ease in which you can access things like your dsmb and spool. Making your life easier is the goal while enjoying yourself. Let me know how you get on.:-)
incredible buoyancy control wow
Thank you 😊
Now that is a solid platform!
Neil Egerton, cheers, that platform was 12m below me :-)
Garry Dallas that's the impressive part!
superb video
Thank you 🙏
Sorry about the glitch half way through, the GoPro went off.
Amazing video! I learnt new way how to attach clip to spool and smb to the reel!
Wish only this video has also subtitles, explaining what those gestures mean.
Roman Markovtsev thanks Roman :-) the video wasn’t intended to be a step by step teaching format, that’s the job for your instructor. It was merely to show awareness off how it can be done controlled and safer :-)
"You watch me deploy smb" I didn't look twice but after deploying I think he said "stop 2 min at 7m" His signals are slightly different than ones I use but then his doubles are sagging too. 😁
@@LarsDennert His hand signals were very clear. "Hold level at 2.7m. "
Beautiful bouyancy and trim
Benje Comans thank you 😊
Immaculate! My ambition is to match the inhale to the drysuit dump.... one day.
That’s the simple part of it, matching the volume of gas in the lungs to the dump valve to the gas in the DSMB
Now we are in the realms of trigasery (trigonometry equivalent??).... nightmares!@@Garry_Dallas
@@user-vk9cw7tg7b haha 😂
First you work with your lung volume, and match it to how much you vent from the dump valve. And the gas in your lungs, then goes into the DSMB
This is GREAT. Just found this as I was looking at many videos trying to sharpen my skills. And to think I was putting the clip on my BC...ugh! Do you have any videos of inflating the SMB with your reg also? And yes as others mention, your buoyancy is crazy perfect!
Thank you Kathy for your kind comments.
I’ve kind of refined the skill more since this was taken (by chance) and adopted it for wetsuit diving using a wing only for buoyancy. I will do a video for this.
As I’ve mentioned just the other day, using the exhaust bubbles from the regulator is ok if you really practice it, to know what’s the ideal position of the dsmb at the side of the head and how much gas to put in the open ended dsmb.
Th boltsnap on the line as you point out is just to keep tension on the line as the line unspools.
The other method of purging a regulator, especially in less than 10’ water, invariably incurs a freeflow. As much as it might be possible for some experienced divers to deal with this situation on top of holding a regulator, reel, dsmb and LOOSE line, whilst maintaining their depth and buoyancy, it’s way too much task loading, not to mention crimping the freeflowing octopus
You might ask why the regulator method was and is being continued to be taught…? Well simply, diving was originally intended for wetsuit and warm water, freeflows although they can still happen in warm water are less likely. Cold water drysuit divers adopted this similar skill from there on.
Does that help?
Awesome demonstration!! Can I ask what smb are you using? Make dimensions ect.
Peter Moore I use a few to be honest. All about the same. But particularly like the Xdeep one for the perfect oral inflate. It’s about 1m high 6” wide.
Badazz!
Well done, mate.
Thank you!!
I hope it works for you too 👌
Very instructive to the finest level of detail. If I may ask, is there a reason behind the continuous stream of air coming out of your mask?
Kamel Ayari I had a tiny split in the mask seal, unaffected by it and didn’t notice it until afterwards.
@@Garry_Dallas Thank you for the clarification.
Hi Gary, superb video, by far my favourite for professionalism. Just one question, how is the line attatched with the bolt snap at the beginning when you pull taught. Thanks.
mlambe77 would you like me to do a video here?
@@Garry_Dallas I would love that :). I watched your video closely several time but can't figure out between the following 2 options :
- Option 1 : You are "unattaching" the DSMB part way, pulling on the small loop tied at the end of the big one, passing this small loop through one hole in the spool, and then securing it with the double ender
Benefits : Securing with the boltsnap easier as there is only "2 line pieces"
Drawback : The knots that creates the small loop can catch the edge of the spool hole when pulling just like you did at 0:38
- Option 2 : The DSMB stays attached all the way, just folding the big loop in half and passing it through one hole.
Benefits : not knot is passed through the hole of the spool, so easier "deployment"
Drawback : I find it harder to manage the boltsnap afterwards as the there is 4 line pieces
Anyway, thanks a lot for your videos, great stuff :).
@@tbltrob thanks for your comments, although I'm not sure what you mean in option 2. In option 1, as you say the drawback catching the knot as it passes through the hole of the spool... easy, build up the line on the spool slightly away from one side of the spool to make sure the holes are free and bigger ;-)
@Garry Dallas Hey thx for the answer Garry. I guess option 1 was the way to go then. For option 2, here is what I meant (a picture is worth a thousand words ;)) : photos.app.goo.gl/tG63bYWwxAfw2wXQ8
And here is what I meant whith harder to manage with the boltsnap as there is 4 pieces of line : photos.app.goo.gl/DigNh893bJpSgMcV7
@@tbltrob yes there is another way, one which I designed and have taught for over a decade.
Would like to see how you stow the pre-rigged SMB and spool. Doesn't appear to be the standard way that can easily come undone when removing from pocket.
Neil Egerton exactly, there is a nice little trick to stowing it away. Keeps the spool and smb together, ideal for recreational divers not wanting to fiddle putting the two together. It's called "tecreational" system. Also used with a boltsnap so it can be clipped to an external D ring.
Hi Garry
How are you?
I know you're a diving lover who gives us more advice.and your videos are more amazing .i love them.
Look forward to your more videos.
Yours
Julia
Have you done any videos deploying DSMB using a reel rather than finger spool? Tend to use these in the UK.
Hi Suzanne, I am in the UK with thick dry gloves. I've used reels but really prefer cold water spools by a long shot, so much less to go wrong, no overspooling, birds nest, ratchet levers sticking/breaking or getting caught between reel wall and spool.
After deploying, would there ever be a need to clip the DSMB to a ring on your gear say, in the event of heavy surface conditions or surge?
As much as it’s possible to do so in certain conditions, it’s not something I would recommend clipping the spool and boltsnap to say a chest D-ring, where it firstly gets forgotten about, out of sight, out of mind. I’ve seen a line from someone’s reel pull a regulator out of the divers mouth as they’re turned around at 30m. I much prefer to see it at all times. I have clipped it to a strap on my wrist before now whilst needing both hands. But that’s what your buddy is for, to hold it 😉
Garry, I'd love to know how you maintain your buoyancy when you've filled the SMB with some air. I didn't see you dump any air... why isn't it pulling you up? Did you modify your breathing and keep lungs more empty than full? Thank you, looks great!
Breathing stays the same, but I dump some air from my drysuit/ or wing depending what I'm using almost equal to the air filling the dsmb.
@@Garry_Dallas Maybe too late for you to notice this but... seeing your comment above, I re-watched and saw air leaving your arm valve on the drysuit.
With no drysuit experience... what's going on there? I didn't see you hitting a button on it?
How does the air "know" to escape?
Ps... so jealous of your bouncy control!
@@derekwalter7100 that’s about being in trim. Let your drysuit/valve do the work for you so you don’t have to. Once you have balance everything is so much easier.
Nice👌
Thanks!
Hi Garry..this one of the best video on smb deployment. Im currently learning how to deploy my 6ft open bottom smb. My configuration is single tank back mount typical PADI setup for AOW.
1. Will i able to inflate a 6ft smb at 6m dept using your method shown in the video ?
2. Will i get too bouyant due to holding the inflated smb while checking for clearance above me.
3. If deploying under current will this method works ?
4. Do u have a video on how to setup a smb n spool ? I seen alot videos with the spool n smb separated b4 deploy n have to attached both togather b4 deployment. I find it not that efficient.
Many thankz for your videos.
Bryant
Bryant Gian Hi and thank you. Do in answer to your questions:
1. You have to remember this is a skills video. In reality you’d send a DSMB up from depth.
Therefore at 30m you fill it 1/4 full before letting go. A huge wide bag is pretty overkill. A tall bag is fine but not 12”wide ;-)
So no need to fill a 6’ bag from 6m.
2. You check above you BEFORE filling the bag.
3. Yes it works under an condition. But neutral buoyancy/hovering Is the key to holding your depth.
4. I will do one :-) having them separate is for technical diving. Recreationally you keep them attached. :-)
Thankz for your quick reply Garry. As i can remember for all my dive the dive master release the DSMB when he/she signal for safety stop at 5m. Then the DSMB will be release at 10m max...some do it at 5m. My SMB is 6ft long , the opening is 7" wide. Looking forward on your spool setup video. thankz again
@@bryantgian4494 For such recreational uses you may want to look at getting a smaller SMB. I have a Tecline closed bottom on about 4 feet long and fairly narrow. It's easy to inflate and should provide enough visibility for a dive boat to find you. XDeep also sells a nice one I think.
@GarryDallas I understand this is an older video, but what mask is the diver here using?
Also- how would a recreational diver prevent her/himself from involuntarily rising with the SMB once she/he has filled it with air? I‘m trying to understand how the diver here has done that, but it looks like his suit is auto-purging?
The mask is just a cheap one, it got broken shortly after lol The new XDeep masks are pretty cool and low profile, you might want to try one ;-)
Any diver recreational or not can achieve this stability in the water.
It's about transferring gas. The deeper you go, the less you need to fill the dsmb for it to arrive at the surface full. eg 40m you need to fill the bag only 1/5th.
First dump the gas from the suit according to the amount you want to inhale. Make sure you dump initially just before inhaling.
Second, blow only some of that inhaled breath into the bag.
Repeat process if necessary.
Spend the time to check line, spool/reel and boltsnap are safe to deploy.
After release, put back air in the suit.
The same can be done for wetsuit when dumping from the wing instead.
Also using open ended dsmb works using the same principle.
Gary, when releasing my DSMB, getting water inside of it... any suggestions? Open bottom, and thinking it’s seeping in through the exhaust valve. Thanks.
If it's open bottom and not fully erect on the surface after deployment, then that's most likely the issue, unless the valve isn't seating correctly, dirt or damaged, worn seal.
@@Garry_Dallas Which dSMB did you use in this non-demo, guide video?
@@johnwilliams2014 I believe it was an XDeep oral inflation dsmb
@@Garry_Dallas Thank you
@@johnwilliams2014 you’re welcome 😊
🤟🤟🤟
I cant stop watching this.. i keep trying in my drysuit and it gets messy .... very messy ..LOL
Thank you for watching! I’m so glad to see it’s been a helpful video globally.
What gets messy?
@@Garry_Dallas joking Garry.. my deployment isnt anywhere as near cool as yours.. not yet anyway.
@@arroyodflint7114 to be fair, and not boasting but my performance in that video was only adequate at the time haha. Maybe make sure you're dumping gas from drysuit dump valve FIRST and almost immediately start breathing in, might sort your problems out. ;-)
So is there a way to get the larger 6 ft DSMB to stand up vertically in the surface without pulling on the line? I got the largest DSMB the store had so it would be easier to see, but fully inflated it won’t stand up.
A tall but narrow DSMB I prefer in the ocean as they are far easier to manage than just any old big 6ft bag. Some DSMBs have lead at the bottom of the bag. Using a stainless steel reel will help also with that additional weight, but personally I dont like carrying these too much for various reasons. A DSMB will not stand up without some help.
@@Garry_Dallas it’s the XS Scuba 6’ x 4”buoy. The lead idea had crossed my mind too. I had the problem with my buoyancy as soon as I’d shoot the DSMB practicing in our local dive shops 18’ pool. I wasn’t a big fan of the stainless finger spools either. I’ve got a Chinese Apeks clone. I’ll just have to keep practicing. Thanks Garry! I just went back and watched this video another three times. I’m not a drysuit diver, so I didn’t realize at first you were venting air while inflating the buoy. Makes a lot more sense now how you kept your buoyancy perfect.
@@Chogogo717 yep it's just a transfer of buoyancy from wing/drysuit to lungs to DSMB.
@@Garry_Dallas I got to go diving for the navigation course this past week. Shooting it from 25’ and letting out just a little air from my BCD definitely helped. The 1-3’ visibility definitely brought out some of my deficiencies in navigation 🤣
@@Chogogo717 just let out enough air that equals what you put in your lungs
This works a lot better if you have good horizontal trim. You may want to swim down a bit when you blow air into your SMB
Carlo Kop yes this works with a static position of good trim “hover”. As you can see my depth indicated was 2.7m here. Putting any air in a dsmb at this depth (70%), even swapping it from drysuit to dsmb, creates an effect, although small, to fill it so it is full by the time it reaches the surface, which is the objective.
By the time you do this at depth, say 30m, you’ll only need to put 25% in it to be full at the surface, a much smaller amount, gives very little need for gas exchange, therefore no need to swim down!
You must dump gas out of your drysuit (or wing) FIRST to compensate for any gas you’re about to put in the dsmb. Otherwise you will go up!
@@Garry_Dallas I'm sorry your trim here is perfect. Good video, this is the way it should be. I was looking a video here before where someone demonstrated this completely strait up. In like a kinda standing position I think before posting this comment your video started, I did not notice. This is a perfect demonstration.
Carlo Kop ahh I see 🤪 thank you. Although this wasn’t meant to be an instructor demonstration, it was meant to demo the ability anyone can have to give themselves time, rather than rush putting a dsmb and hold more accurate position :-)
Why the finger inside the spool (Apeks has larger hole than other manufactures, for their spool it is dangerous)?
Why the bolt snap on the line?
Why shoot using a left hand?
Hi Jiri, I hope you enjoyed the video.
Answering your questions....
In reality you don’t need to have a finger in the hole, but very much advisable to save your face when you drop it (not being in control) in front of someone. The hole is large to accommodate a large finger with a 5mm neoprene glove.
Boltsnap on the line applies tension to the line, preventinga birds nest while the spool rotates taking off the line from the spool.
For the purpose of this video with my set up, I choose to hold in the left hand, so the right hand can easily take my regulator out.
The principle is still the same, although depending with open bag or ‘bottle’ versions the regulator will stay in the mouth and either hand can be used.
Hope that answer your questions?
@@Garry_Dallas sure, thank you. You know, there are different ways how to do it and without explanation, you can't understand it from the video. This explains my "Why" questions.
@@askingdiver happy to answer your questions... It was not intended to be an instructional video to be honest. That's why we have classes.
elegant
Thank you 🙏
@@Garry_Dallas Can you post more dive or skill videos? I'm your fans😍

Best video EVER!!!
Thank you!
It wasn’t intended to be a demonstration video for the dsmb skill. It was just to show buoyancy control while doing a complex skill. But it seemed to work for both anyway, thank you 😊
Wish I knew sign language
Needs a voice over.
Oh... do you have a suggestion? 🤪
Could. You not just use air from your exhaust t when you exhale instead of removing your 2nd stage
sayittrue yes if that was that kind of dsmb. I prefer oral inflation dsmbs as they are more reliable. Open ended with the restriction is a pain to sort out when they stick closed.
@@Garry_Dallas true
Almost as good as mine........!!!!! :-0
ua-cam.com/video/8AhFS9fE4ts/v-deo.html my favorite part of the video
Haha yes it’s pretty significant and people remember which finger to hold the spool with 😜
The only positive thing I can say here is excellent buoyancy what a faf
Thanks for your comments. Would you like to share your method?
I’d be really interested to see it being done more efficiently and safely.
@@Garry_Dallas why on earth advocate removing your life support to inflate dsmb mess that up your in a world of hurt unsafe practice, have your reel and dsmb already attached to each other and deploy using octopus or second option from exhaust from main reg
@@hdunbavan4844 thank you for taking the time to write your comment.
As you can see from the video, both my dsmb and spool are attached.
There are actually multiple ways to inflate a dsmb, clearly obvious by the fact that Halcyon and XDeep, to name a few manufacturers, have designed an oral mouthpiece, to which a diver can orally inflate. As long as the regulator they are using is in their hand when they take it out of their mouth, there should not be a problem putting it back in their mouth. It’s one of the very first skills taught in scuba diving, correct?
Using an octopus is used on open ended dsmbs, but causes issues, such as free flows while both hands are in use trying to hold 3 items, regulator, dsmb and reel.
You can also opt to use a separate QR inflator hose to inflate the bag.
It’s also useful as you say to use the exhaust gases from the regulator, although it’s not as easy to control or know how much the bag is being filled, as opposed to directly breathing from the mouth.
Although the actual process in every situation of filling a dsmb has it’s nuances, holding all the equipment necessary can be a juggling act, but the biggest issue is losing buoyancy during the act.
I’ve witnessed people getting tangled up in their own line, lose equipment, go up, go down, lose their regs from being caught on their up-line as they deploy, crack bottles not working, freeflows, to name some of them.
We have to mitigate all of these issues into something that can be effectively achieved in a controlled manner, and this is something I came up with.
The key point is controlling buoyancy throughout the skill, which is what I show as I vent the right amount of gas from my drysuit (or wing if using wetsuit).
Nah..not for me...I prefer to practice in real environments (Currents/tides), where you are not looking at the sides of the pool for a reference point! Good instruction though on the principles of this skill.
Pugwash Diver thanks for your comments :-) instructional skill is what it is and practice is where divers do this before they get out in the sea. It combines 2 skill elements, good “buoyancy and trim” and DSMB deployment.
Personally i don’t think I need to practice much at this level in a pool but always put up DSMBs on a dive, but then this video wasn’t really for my benefit ;-)
Way to many steps
Really? can you explain which steps you're referring to? ie from the point you start adding air or taking it off your D-ring? This kind of demo was not designed to be instructional, just to show it's very doable. The instruction of course, I reserve for my students.
For me, this is a skill that divers should take their time, rushing hastily only causes problems, problems one doesn’t see until it's too late.
Once the equipment is in front of you, transferring gas from one buoyancy aid to the other allows a diver time to be calm and send up the blob more safely.
I can deploy a SMB in 10 seconds. Stop juggling around from hand to hand. Be fast. Air is precious.
I’m sure you can! It’s not about speed, it’s about safety.
@@Garry_Dallas Air is safety. Don't waist it.
nunogirao air is only safety when you have it. Good plans, like rule of thirds, give safety and hence sufficient gas, allowing less stress or anxiety to perform a task. Rather than flying by the seat of your pants!
overcomplicated crap
Would you care to show me a more simple technique? I’m always open to ideas, especially if it’s more safe and easy.
