Dive shops love to sell yolk regulators to their beginner students. This way, when they start taking more advanced training the student has to buy another set of regulators from that same dive shop.

Well pronounced DIN, James. For a non-german it sounds good :-) From an engineering/technical perspective, the DIN reg is more reliable and a better solution. I can just confirm your suggestion: get a DIN and an adapter.

DIN all the way, for exactly the reasons you mentioned. Plus when DMing i use my personal Steel 117 tanks filled to 3400 psi, i get a full day of DMing off one tank that way. I couldn't use a yolk reg for that and I'd need to swap tanks, pulling me away from prepping the site and taking care of students. I don't like waiting their time or money.

Nicely explained, Thanks James!!

A concise and clear overview which told me everything I needed to know. Thanks James!

DIN regulator. Just the most common type you find around here in Denmark. Very easy to use, if your flask already has a DIN threading. I like the more compact style as well. Edit: I will add that in cave diving DIN does not stick out towards the ceiling, minimizing risk of knocking it against the top of the cave, if you miss judge the height.

Good video, I have always used Yoke, but my next setup will be DIN for sure.

Straight to the point and no bs. You just got a sub for that

Thanks James. DIN for diving in Australia & Yolk for diving through Asia (tanks set up & swapped over on boats by dive crew - Indonesia etc). I hope Scubapro release the new MK19 for individual sale - sealed first stage with swivel head and five ports - the perfect combination of MK17 & MK25 EVO. Keep safe & well 👊. Simon

Don't get me wrong I am a fan of DIN. But I believe the best travel system is a yoke reg along with a spare "doughnut" insert for DIN tanks. If you travel with a DIN reg, yea it weighs less, but if you need the A-adapter just in case you run across some yoke tanks your weight savings just went overboard. Plus it sticks out way worse than a natural yoke reg. If you have a Yoke reg, all you need to make any din tank yoke compatible is the little doughnut insert that you showed in the video. Moreover the little doughnuts are like $10 a pop (I always keep a couple in my SAD kit as they contain 2 orings each). The A-converter is like $50-100. Anyway. Love the videos keep up the great work. Cheers!

My side mount regs are DIN and my rear mount rec set up is yoke. All the tanks I’ve come across in Australia have DIN valves with insert as default. Great video again.

Thank you very much for this vidéo. I’ve been using my mk17 for 20 years and I love it. Beside, I’m considering to have it converted to DIN

Thank you James for another informative video! I have about six yoke reg systems and my fiancee has two. We learned on these types of regs as I learned to dive in Guam , she in The Philippines and we primarily dive there as well as Thailand. I mistakenly purchased a Din tank a couple of years ago and oh noooo. the cost of a din reg system is extravagant and mine was the type that couldn't be converted with an adapter. So long story longer I don't know the joy of diving with a din tank/reg or having a larger fill (3500 PSI max)I couldn't even sell the tank here in Guam despite it being in great shape! Ultimately since I have 9 other yoke style tanks it's not the end of the world. I'm sure at some point I'll acquire a Din reg......

I just bought my regulators a few weeks ago to finish my Advanced and Rescue courses and I bought the Scubapro MK17 EVO/ G260! I'm so excited to get back in the water and test it out :D. I was between the Scubapro MK17 EVO/ G260 and the Apeks XTX50 but decided on the Scubapro because it was cheaper and had a few stylistic details I preferred and, perhaps most importantly, because Scubapro doesn't need to be serviced as often and the rebuild kit wasn't as expensive. I spoke with my instructor and decided it would be best to get a DIN first stage with a Yoke adapter and I'm all set to go! Happy Diving :)

I love DIN. For a couple of big reasons you mentioned. One... I have a yoke converter for travel in case the dive operator only has yolk valves. Most of all the low profile and less weight. The DIN screws into the valve which makes for the cleaner low profile, less knobs and metal sticking out all over the place. And no blowing up O’rings.

My first regulator was was a yoke. I had it converted to DIN at it's first service. There wasn't any need to buy a new set of regs and the price of the conversion kit was much less than a new set anyway. I still use it today when I'm teaching open water courses. All my many other regs were bought as DIN and I just take an adapter with me when I take them overseas. Here at home in Australia and most places I dive overseas in the last four years have convertible tank valves anyway. I take the adapter as insurance because some of those tank valves haven't had the inserts removed in a very long time and can be corroded in place.

Great info

DIN all the way. More secure, lower profile and less chance of an o ring becoming dislodged and letting go. An A clamp oring letting go in the water isquite spectacular.

DIN actually stands for Deutsches Institut für Normung (German institute for standardization). It is also often (falsely) referred to as the Deutsche Industrienorm (German industry standard). The word combination James used there is not quite correct. However, the pronounciation was absolutely great and the video is perfect as always! Keep the great videos coming!

The din is just a pain in ass when I have to fill tanks have to put all the plugs back into the tanks to fill. But I love that that can change back and forth

DIN here from Canada. Three reasons: 1) Versatility for traveling. I have a DIN to Yoke adapter. 2) I have bought a HP steel tank although it's not over 3500 psi, I just feel more secure with DIN. 3) Less bulky behind the head.

DIN for the wife and I with adapters to toke just in case. Reason the regulator we chose was DIN at the time. No after learning more I would stay DIN because because I has less parts in it and can give us the advantage of diving at higher pressures

DIN may be better from an engineering standpoint, but yoke is definitely more common. In Asia and the Americas, where I do all my vacation diving, I have only ever seen yoke.

Since I am from germany I use DIN. Here in europe it seems to be the standard. But I got a converter for free where I just had to pay the porto (still thankfull)

DIN for the win. It's more secure. It's capable of handling higher pressures. It's smaller. It's lighter. You maintain the o-ring yourself. It will fit any cylinder valve (with an adapter) (except M26). There are no downsides to using a DIN regulator.

On my very first reg so it’s a yoke style because that’s what they had on the shelf in my price range. Considering a din for next one

I am a prophet for the xtx50. I have 3.all DIN. My wife uses xtx50 too, but she's a yolk girl.

I dive with a Pro k valve. DIN is more versatile, but at my location all the dive charters carry yoke, so with the Pro Valve I can easily switch to either. As for my Reg, DIN.

Have been diving DIN regs for over 30 years. In the past normalisation of yoke used to be a problem and I have suffered catastrophic gasloss with a not fully compatible tank-yoke combination. Never had an issue with a DIN reg. Also DIN regs exhibit a lower snag potential for nets on wrecks

Dive DIN. Find it way easier to use and it is really hard to make a mistake when you get your gear ready. In NZ most operators seem to have the inserts for the tanks, and when I was in Chuuk (Truk) they had DIN Ali tanks there.

I live in Georgia and dive mostly springs in Florida. In this geography, yoke is most common. Wouldn’t having DIN with adapter as the norm create an additional failure point by having two connections (adapter to tank and DIN to adapter) Instead of just the one (yoke to tank). New diver trying to learn to think through these things. Thanks for all of your content!

@bloodymarvelous4790

Anytime you add an adapter you add a failure point. If you're using a Yoke valve adapter you have an insert with an o-ring on the inside, and an o-ring on the outside. The chances of the o-ring on the inside failing are next to nothing. If you come across a worn o-ring on a ring adapter, screw it out, and turn it around. (Or better yet, ask for another adapter ring). When you add a Yoke adapter to a DIN regulator, you have the o-ring on the valve, and the o-ring on the regulator. The chances of the o-ring failing on the regulator are next to nothing. Another disadvantage of the Yoke adapter is that it makes the regulator stick out quite far from the cylinder valve. So you're basically compounding the disadvantages of a Yoke valve connector. Now it's sticking out in the back AND the front. Fortunately, there aren't that many dive operators who still use Yoke valves. Most use DIN valves with a Yoke adapter ring. So you'll rarely need to use the Yoke adapter.

Which one is best for spear fishing

I am just starting. I was given a yolk. Not a choice. I am interested in trying the din because I have to travel for diving. I like the idea of the din which would allow me the option. I like the less weight. I usually want to bring stuff home.

I started diving in South America with INT, and it was difficult to understand how DIN worked. My regulator is DIN, because I live and dive in Europe. Cheers

DIN all the way. it is just a better connection and if you want to venture in tec you will need DIN. As James shows, many cylinders can be converted and you do not even need to use a DIN/Yoke converter. As always, James is spot on :-)

I use only Din. I did not cert on Yoke and didn’t really like how it fits and sticks out. I also dive with HP Steel tanks and are rated for 3325 psi. I really like the low profile of the Din

Do you have any videos of you diving?

DIN was developed in the US and adopted by DIN, that is why it is 5/8” vs the metric like the M26 that DIN developed.

Thank you. I knew the Din was a Thread on. But didn't know it was rated to handle higher PSI. Having worked as an Auto tech, Fewer connections means less chance for leaks. The Adapter kind of makes sense in a pinch. I would rather have the Direct Connection.

Older DIN regs are also 200 bar (or 232) too, so if someone wants to use 300bar tanks make sure the reg is also 300bar rated, with the longer thread. BTW older means not that old, like my Scubapro MK16 and MK20 was also 200 bar.

Taking about midle Europe, i have seen only DIN.

DIN is definitely better. However, geography may force one to use yoke. All my regs are DIN but I do lot of could water diving in northern Europe. Als, as mentioned on video DIN is the choice for stage and bail-out regs anyway.

i use DIN regulators because i use with 300 bar steel cylinder and because it is easier so i use an adapter for int bottles

Your video is perfect timing. I am considering having my lds convert my yoke regulators to din with a conversion kit. Reason being: I dive high pressure steel 100s. I regularly get fills slightly above 3400 (NOT Cave fills). My o rings fray and blow all too often. I own three regulators and the conversion kits are $50, $100, and $150. Also my tanks easily convert to din. Should I convert? Thx 🐠🦞

Is the 'O' ring the same size for both DIN and Yoke regs?

If I was buying again I would buy DIN. Most dive shops prefer DIN. You can also accommodate higher pressure (ie more air) in tanks so good if you're a heavy breather. O-Rings also tend to fail more in yokes as there is more pressure put on the O-Ring when the pressure is released for the first time (like out on a dive boat or just as you're testing the tank pressure before you get on board...You can always buy a few adapters. From what I hear- ice diving almost always mandates DIN for safer diving (and you suck more air in cold environments)

The difference of working pressure between DIN and Yoke is not because of location of oring, is because of the diameter of screw which keeps the regulators in place. Because you have a larger diameter, a lot more grip to valve. And, yes, DIN is screwed into the valve, as you said, becoming one with the valve. But the diameter of the screw is a big factor when you work with this pressure.

And some with the inserts couldn't remove them coz they'd been in so long. And using the adapter makes the setup longer and hits the back of my head. So for less hassle I travel with my yoke setup. If the dive shop I'm traveling to can tell me for sure I can use DIN setup, I'll take it. If they tell me they mainly use yoke and should have a few tanks with the inserts they can take out........ I'll take my yoke.

I use and prefer DIN but there is one advantage I see for yoke and it is the durability of the valve (without reg attached). Drop a tank off bench onto deck valve first. It does not take that much of a hit for the din valve to get deformed and no longer able to recieve the reg. This is one reason I think the high volume boats for rec divers might favour the yoke tanks.

DIN is both stronger and more versatile. It's a no-brainer. However, A DIN with a-clamp converter is a pain. It defeats the weight argument, as the combination is heavier. And a DIN with converter sits closer to your head than a native yoke, because the DIN screw doesn't disappear, so that can be uncomfortable.

And you have to put up with the condition of the valve thread you use when diving on vacations around the world some of which I have seen I would never risk fitting my din into. It is fine if you dive with your own cylinders since you would maintain both but not when you travel. In 30 years of diving never seen a full oring loss on "A" clamp however seen 9 din failures due to cylinder valve threads which had not been looked at forever. So the oring housed inside was irrelevant.

From where I have dived ( south east Asia , Taiwan, and japan) is more common for yoke, I even not sure the tank is ok for din

Yoke

Both of them in sa

I've heard that you cannot dive a HP cylinder with a yoke valve because the yoke connection cannot withstand the higher pressure. However, a HP (3442psi) 117 from Faber comes with a yoke insert. I used it as yoke many times. Never had an issue. Not saying it wouldn't have eventually blown the Oring but it did make me question whether or not its true that yoke connections can't handle HP.

3442psi (about 237 bar) is not an high pressure but is just a bit more than the maximum limit of the yoke (232 bar or 3365 PSI) which is the same value allowed by a LOW PRESSURE DIN (5 threads) An high pressure DIN regulator (7 threads) can handle high pressure DIN cylinders (300 bar or 4351PSI) and can be also connected to low pressure DIN cylinders (232 bar, same as yoke)

DIN to win. I prefer using high pressure tanks for their greater air capability.

Yoke is used worldwide (even in Europe and Africa, where DIN is quite common as well), if you have a yoke regulator you will find a cylinder everywhere in the world (but is bigger and cannot accept very high pressure cylinders!). If you have a DIN regulator, you may have troubles in some countries (unless you also have an adapter) but you have a smaller and lighter unit that can be also used with 300 bar cylinders (i.e. much more air available!).

Din is the way to go as said lower profile, higher pressures and can be converted if needed. Why on earth would you still want a yoke entanglement hazard and less bottom time

DIN = "Deutsches INSTITUT für Normung", or "german standards institute" - but "Institut(e)" not "Industr(ie|y)". Some people also call it "Deutsche Industrie-Norm", or "german industry standard", but that's of course INKORREKT. 😁

Was that a garbage disposal jam buster wrench? LOL

Not really sure why manufacturers bother with the cost and effort of maintaining two SKUs on their mid-high end regs when they could just make Din regulators with a yoke adapter built in, and one product covers all markets. I bought my Mares regs in yoke and had them converted to DIN, then had to get a yoke adapter to go the other way.

Nice video, but your explanation about DIN pressure is not correct. There are 200 (232) bar DIN regulators. It comes down to the number of threads. 5 threads DIN is 232bar 7 threads DIN is 300 bar. Quite some beginner regulators like the Aqualung Calypso, are only 232 bar regulators. Hope that info helps some of the readers.

Prove it

I'll admit it's a little nit-picky, but I'm pretty sure DIN had nothing to do with the development of the DIN regulator. DIN is a standard for industrial machining, including screw threads. The DIN system uses a DIN screw thread to connect to the cylinder valve. That's where the DIN name comes from, not because DIN developed the connector.

DIN as everything German is a precision item. Put it into high numbers of students environment, like dive centers in the tropical destinations and you end up with broken threads all day long. I've seen a student put a yoke in opposite direction , driving the screw into air inlet 🤦‍♂️🤦‍♂️. But with those fantastic tank valves that can be converted, I think yoke will become history over time since before many fast afraid not to find a DIN tank in some areas, same reason my first reg was a joke.

As far as I can tell, from experience and your video, there's no advantage to Yoke, it's just a hangover from the American (and local) market clinging on to them while the rest of the world had moved to DIN. That said, for most divers, Yokes will work just fine and there's a lot of great used gear out there with Yokes for peanuts and, as said in the video, the actual regs are just the same in most cases. I've seen quite a few Yoke O-rings fail (usually when pressure is applied to them to be fair, so an inconvenience rather than disaster), but never a DIN one.

Displacing a dominate system requires both that the old system to not be good enough, and the new system be clearly better. Yoke is good enough for most divers.
