#173 Additional Techniques to Help Prevent Incorrect Decompression Gas Switches
Переглядів 6213 місяці тому
In this video, we discuss additional techniques beyond analyzing, marking, and notox to help prevent incorrect decompression gas switches. This includes the use of color coded hoses, face plates, exhaust defectors; and labels on second stages. These are not meant as replacements for proper practices, but further measures to help prevent incorrect switches.

#170 - The Crotchless Crotch Strap For Scuba Diving
Переглядів 4544 місяці тому
In this video, we discuss some reasons why divers do not use crotch straps. If you find conventional straight or Y shaped crotch straps uncomfortable, an alternative is the crotchless crotch strap. This assembly consists of two leg loops, so nothing comes in contact with the divers crotch. Unlike safety harnesses, the leg loops should not be too tight or they will prevent the diver from kicking...
#169-The Dump Valve-What is it, when to use it, how to use it for recreational and technical diving
Переглядів 6634 місяці тому
In this video, we discus the dump valve. The number and positioning of dump valves vary wildly with recreational bcds and technical wings. In some positions divers may not be able to release air using the inflator. To effectively be used, the toggle string must be pulled toward the surface. Better yet, remove the toggle which can be trapped and just use the string.
#168 - Life After TDI Extended Range / Trimix or PADI TEC50 / TMX50
Переглядів 3085 місяців тому
In this video, we discuss what divers do after completing either the TDI Extended Range / Trimix or the PADI TEC50 / TMX course. One option is to continue to dive at the current level. Another option is to switch to closed circuit rebreather training. The last option is to take a hypoxic trimix course.

In this video, we briefly discus the resistance to sand penetration of the Altama Maritime Assault 8 inch version boot. Neoprene socks and a full length 3mm were utilized. The legs of the wetsuit were pulled over the top of the boot. Very little sand penetrated the inner boot. However, the dive was conducted at a site with only sand, no surf. The next update will involve the performance of the ...
#165 - The Helicopter Turn for Technical Scuba Diving
Переглядів 2845 місяців тому
In this video, we discuss the helicopter turn propulsion technique. This is used to establish and maintain team position. With the helicopter turn the diver rotates around their current position without going forwards or backwards. While the actual mechanics of the helicopter turn can be complex, it is often more intuitive form many divers than other propulsion techniques.
#164 - Back Kicking For Technical Scuba Diving
Переглядів 5056 місяців тому
In this video, we discuss the back kick. This is commonly used in technical diving for establishing and maintaining team position, particularly during decompression stops. In order to effectively back kick, it helps if you have a fin with a high sidewall and that you have a proper horizontal trim position. This version of the back kick consists of four steps. If you do not have horizontal trim,...

It's help full
I just completed basic nitrox class yesterday. Thanks for your detailed explanations, Chris! I'm looking forward to this class.
Happy to help in any way.
@divezonescuba Chris, do you blend your own gases at home? Or do you just buy fills from your LDS?
@ Hello. I actually do it at the shop myself as a nitrox and trimix blender.
@divezonescuba Chris, you're the best person to ask this question then: which blending method(s) do you recommend to someone who wants to blend nitrox and trimix RELATIVELY inexpensively at home? (I know that helium is expensive, no matter what.)
@ For an inexpensive approach, it depends on whether you are doing just nitrox or trimix. If you are just doing lower % blends nitrox, continuous blend mixing is better than partial pressure blending as you don’t need an o2 clean compressor system. You can also use down to the last 50 psi in the o2 fill cylinder with continuous blending which you would only be able to do with a booster for partial pressure blending which is expensive. The only downside to continuous blending is that you should have a commercially made helix blending tube. Don’t use the golf ball method described in the oxy hackers guide, which is a good source to have anyway, just take some of those ideas with caution. For trimix blending, the first problem is getting someone to sell it to you. If you can get it, you can do partial pressure blending by filling the helium first and then continuous blending in the rest of the mix to get the percentage of trimix that you want.
One question, why do you actually decompress at 6m with 100%O2? Isn't it dangerous to leave the partial pressure at 1.6 as standard? You should never go higher than 6m because of the decompression, which is why you should stay a little lower at 6.5-7m, right? The partial pressure there is then 1.7, which according to the CNS table you can only withstand for 10 minutes. If you accidentally sink 1m, you quickly reach 1.8, which you can only withstand for 1-2 minutes. Wouldn't it be smarter to decompress with 80%O2 in the upper stops to be on the safe side?
@@strolchtv86 one common standard is to use x100. The limitation is that if you are at 6 m / 20 you are at 1.6 ppo2. Most agencies limit the ppo2 to 1.6 regardless of the depth. Speaking from personal experience you don’t want to exceed 1.6 by going deeper. In my case, I was fortunate to have exhibited symptoms that I recognized before convulsing. So, with x100, I will not go deeper than 6 m / 20 ft. Most people cannot stay exactly at any depth, so you still have to be careful. Other divers prefer to use x80. That does give you more margin of error in your depth with respect to cns o2 toxicity. It also allows you to switch at 9 m / 30 feet. However, getting x80 may be more logistically difficult to acquire.
Take a shot every time he says 'aaah' or 'um'
And with THIS, you have officially caught up to the same design that we have been using for years in military diving, mimicking the yates seat harness used for rappelling, hoisting, and climbing. Note: Cobra buckles are not "mil spec", although they are used a lot these days, and the term "mil spec" is beyond highly laughable. It would be wise to stop using it to associate something with a sense of "quality". Just a pro tip. ;)
I heard initially that she had no suit inflator hose. As you say, she did but it couldn’t be connected. Also, the suit either flooded or she got squeezed; it can’t have been both.
Where do you recommend finding an appropriate toggle?
"PADI has a full technical program..." 🤣🤣🤣🤣 Comedy gold!
I don't think any of these methods are practical. While you can perform the assemblies on a tabletop (and some with difficulty), none of them could be performed to stow your spool after use while you're still in the water.
Brilliant. Love your tips.
How about to do the videos also with metric(normal) instead of that imperial that is used in one country only when you post online(worldwide)? We would take your videos more seriously then.
Very nice summation and comparison, thank you.

Which agency teaches that v drill?
How to you attach a DPV???
(Fry shut up and take my money meme) 💰
How were the boots Chris? Thanks for all the hard work!
Thank you 🙏!! The correct term is “leg loops”. This what I’m after. I can’t believe that NO sidemount BCD manufacturers currently offer leg loops instead of the crotch strap. They are all a bunch of ‘follow the leader’ idiots! This is 2024. The crotch strap should be gone by now. I refuse to pay top dollar for a stupid crotch strap! I want leg loops.
Can you advise if i rotate allover when i decent from serface
@@alzahraniabdulrahman hello. I am not sure if I understand your question. Are you saying that your body rolls upside down when you descend horizontally in proper trim from the surface?
@@divezonescuba yes , when i was using BCD jacket style, i can sink without any problem but now when i try to learn with wing backplate , i try to sink from surface , i deflate the wing , breath out , then i sink but the tank rotate me is there any advise for that
@@alzahraniabdulrahman ok. Tell me how much and where you have your weights placed and what kind of harness are you using one piece or adjustable.
@@divezonescuba i have all of them in the back of the tank around 12 kg distributed evenly in pockets and cam weight in the end of the tank and i use normal harness with D ring to keep my camera buckled
@@alzahraniabdulrahman if you are loaded like that, what you are experiencing is not abnormal. Try moving the bottom weights to your belt and the ones on the upper tank band as close to the plate as possible on the back.
Thanks, Chris, always enjoying your tinkering, tips & tricks. Personally, I'm a big fan of Sump UK; Andrew's approach to leg loops is simply elegant (as are most of his designs). I can't judge which system is more comfortable, both are diverting the strain to the hips, similar to climbing or safety harnesses. But I understand that we (divers) want to be able to get out of the harness relatively quickly & easy. I have nothing against quick-release buckles, but I do believe that metal buckles should be preferred in technical diving. Not that plastic ones are unreliable or unsafe, but they can break, usually during transport or handling, and this, you normally find out when donning (been there).
@@mattvish2591 Hello Matt. Thanks for the input. I will have to check those out. There is a milspec plastic buckle manufactured by Cobra. I use those on my DIRish plate and wing. Those are solid plastic and pretty heavy duty. I may make a set of the leg loops with those instead of the normal plastic buckles which I know what you are talking about, having experienced that once.
Always love seeing your innovations! Do you have a video on how you sew and add the eyelets?
I have eliminated the grommets on version 4 in favor of sewing. I originally thought that the grommets would allow some pivoting of the different parts, but I think that is not necessary. The grommets were also a bit hard to align properly on all three pieces of the webbing.
How did you go on with pinching in the 8 inch boot when finning? Thanks Jc 🇬🇧
@@johncooper3171 I did not have any pinching issues when finning. I did not really notice any difference at all.
What is that octopus holder and how do you hold it?
@@ee02108 That is actually an alternate second stage regulator holder. The holder fits into the opening on the low o2 gas regulator. The holder itself is attached to the rigging kit. In order to use the low o2 regulator, you have to go thru the extra step of removing it from the yellow holder. So you have an additional opportunity to confirm that you are using the correct gas.
I thought about doing the same thing with my hoses and regs and glad to see it confirmed as a sound option to help increase safety when grabbing the wrong gas can kill you at depth.
The color coding is not just good for you, but you can also tell at a distance if someone else is using the wrong gas for the depth. It is particularly important in the case of an individual that is distracted or suffering from narcosis.
What happens when you need to swap stage regs last minute? This entire system falls apart.
@@flymol0 Than you move the label or other color coded components as necessary and you are no worse off then you were before.
@@divezonescubaor more likely someone breathes the wrong gas because they were relying on color coding instead of proper switch verification
@@flymol0 I do not have any statistics on that. On the other hand many people have improperly or failed to analyze or label tanks. And some others have just put the wrong regulator in their mouth, which these additional measure are intended to help reduce. The color coding and labeling also assists in putting the correct regulator and hose on the correct tank. Green o2 label on the tank, green regulator. In addition some o2 dedicated regulators are only available in green coloring.
Hi Chris, what kind of labels did you used? Awesome video🎉
The top gas computer switching labels were from Amazon. The bottom ones were from a brother label printer. It connects via Bluetooth to any device. You could just print all the labels on the brother printer.
I already use different coloured hose for this purpose, but not yellow. Yellow should stay as the colour for an OOA emergency. Hence why my primary long hose is yellow. Also, I find just putting a piece of white/silver Gaffa tape around the hose near the second stage that you can label the mix/MoD with a sharpie works just as well as the label you've put under the mouthpiece/on the exhaust T. My issue with the "label maker" label you've put on, is it is awkward to remove and replace, whereas Gaffa tape can be easily replaced and marked with a sharpie without much effort if you are diving with mixes that aren't always "Nx32" for instance. I can see how the maker label would work for a GUE "Standardised gas" model of diving, but sometimes we get the gas we get, and as long as it's labelled correctly and the dive properly planned for the gases we have, then so be it... I do like the idea of a label under the mouthpiece/on the exhaust T reminding to confirm the gas switch on the DC though, that could easily be a permanent add. One more step that I take if I happen to be solo, rather than team diving, I also put a gaffa tape label across the mouthpiece as a physical barrier that I have to remove before I can perform a switch. I don't use it in team, as I wouldn't want a team member to have to remove the label should the need for them to use the gas arise. But I might, as on reflection, this could also prevent an OOA diver taking the wrong reg by mistake in the panic of an OOA emergency.
Video #6 for the backplate backpack for anyone interested! Such a great idea for traveling. Thanks for all your great content!
Make sure if you are traveling on a metric Airline that you meet the metric limits. I got burned on my last Air Canada flight to dive wrecks in Newfoundland. AC policy: A standard carry-on bag measures 55 cm (21.5 in) in height, 23 cm (9 in) in depth, and 40 cm (15.5 in) in width, while a personal item adheres to the following dimensions: 33 cm (13 in) in height, 16 cm (6 in) in depth, and 43 cm (17 in) in width. My carry on was 1/2" to large and had to be checked. Personal Item was fine but barely matd the 6" thickness. The bonus of the trip was check bag limit was 23kg (50.7 #)
@@BrianEhrler There was some bad information going around that the EU had implemented a standardize carry on size of 20 cm for the thickness on 1 SEPT 2024. Fortunately, that apparently didn’t happen. I have not heard of a carry on sized bag that is that thin. If they ever adopt that it should really be 23 cm. Otherwise almost everyone’s carry on bag will be disallowed.
Lol you suck. Get a pilot's license.
Can you use a necklace for your primary if you're a recreational diver, rather than using the necklace for the octo?
@@MrPhoenix357 Absolutely. The donation procedure is different between technical and recreational diving. Many recreational divers use a necklace on their normal length hose primary regulator that is in their mouth and donate the yellow alternate. In fact, I once had a recreational student who kept dropping his primary out of his mouth for some reason. I ended up putting a necklace on it and tightening it so he could not accidentally drop it out.
Hi, first of all, thank you for your video! 😀 I have a question. What if I'm traveling without a travel agency? Should I provide the information from the Airbnb I'll be staying in?
Yes, just where you will be staying.
Sagir E Visa Egypt Country. E Visa system could not understand for Sagir Ahmed. But now Visa confirmed from Egypt country for me.
Great recap, thanks for the tips and trip report!
Awesome video! Time to sit down and get my bolt snaps in order! Thanks, Chris
Were you the only diver with a twinset?
@@theantiquescubadiver I was diving with a set of independent doubles on that trip. I do not consider that configuration to be a twinset as in a manifolded twinset. There was a diver on board who did dive with a manifolded twinset. I did not dive a twinset on that particular liveaboard as they charge an additional 90 euros a week for the twinset, but only 30 euros for a second tank.
Were you the only diver with a twinset?
Thanks for your reply. I started to dive independent 12L back-mount this year and I am considering using the same configuration on a live-aboard in Egypt in September. Your video was very interesting and informative. Thanks!
Did you dye them brown
No. They come in that brown color in addition to black and some camo versions. The previous pair that I had was black, but were a bit tight. So, when I paid for the second pair, I decided to go up one half size. Also, sometimes boat captains when they see a boot like that in black think that you are going to mark up their deck. Not a problem when they are coyote brown. See video #171 for the final sand test verdict.
Thanks for a great video Chris. Always interesting. I know you did videos on the PADI TEC 40, 45, 50 in the past, if you have time, could you do one for the trimix 65 and 90 as well at some point? Much appreciated.
Those are way overdue.
Why don’t you use standard metric that is used in literally every country on earth except us? At minimum use both if you insist of using imperial… super annoying. I mean , you maybe don’t care about the rest of the world or?
@@danielvanderblij8007 High time.
@@divezonescubai mean, even the name of the course is in metric!?
You absolutely CAN improve your consumption. Slow it down with shallower breaths more frequently. No skip breathing tho! That gives the nastiest headaches.
Thanks Chris !!!
Thanks this is very useful
What do you wear for socks? I tried to use Chuck Taylor’s but my RK3s hurt the top of my foot when I wore them.
@@markmild251 waterproof 1.5 mm neoprene socks. I use either deep6 or aquatec fins. Since the top of the Altama boot is higher than a conventional boot, I can see how that could be an issue with some fins.
I’m interested. Do you have a parts list or do you offer a kit? I did not see it on your website. Thanks
These would seem to work well for wet-wading anglers. Looks like they could withstand a couple mile hike-in followed by a day in a river filled with gravel, sand, and boulders. A good price compared to summer waders from fly fishing companies, and a somewhat different feature set. I have some mids on order but after seeing this I'll probably exchange them for the 8 inch version. Thanks for the sand ingress test - that's an important factor for me. Cheers!
We know you are real diver because of the mask tan.
