Getting new reg. DIN v. Yoke

[USC8791]

Thanks for all the great advice! I'm probably not going to get my own tanks, at least not in the forseeable future. Diving has to take a backseat seat to waterskiing, so I'll probably be sticking to singles, Al80 most of the time or Steel120 for the NC wreck stuff. Sounds like yoke may be the best way to go now (i can always convert). Out of curiosity though; are there any drawbacks to the DIN to yoke adapter as my main connector (i.e. comfort, long term reliability etc...)? Thanks again for the input.

Also, before I begin a new thread in another section. Does anyone know of a past thread that fully explains the cons of the suunto wrist computers (mosquito in particular). I've done searches and can't find a specific thread. I keep seeing various responses about being locked out if you surface too soon (or something like that). I just don't want to start another "beat a dead horse" thread. Thanks.

Is the DIN just for diving doubles? Im a noob, never heard of this stuff before. So what i gather is go to scubs.com and get a good reg that come with a DIN that has a free YOKE adapter.

I don't want to misquote or oversimplify things, but the DIN is kind of like what some gas grill tanks went to several years ago. Veterans please correct me if I am way off base.

Come on guy's din is far better than yoke there a reason tech divers use it

1. holds more pressure 3500 Psi +
2. flows aboult 150% more air than yoke
3. internal o ring so almost no place for failure

Dude go din and get the adapter

To simplify, there are two ways to attached your first stage to a tank: DIN and Yoke.

Yoke is the thing you most likely learned on, the U-shaped loop that screws down from the back to press the tank valve into the opening on your first stage.

A DIN connector is a screw-on, threaded section coming right out of your first stage, and the whole U-shaped part is missing. It screws directly inside of the tank valve, trapping the O-ring inside. Makes blow-outs damn near impossible (not that they happen all that often anyway), and also can withstand the higher pressure HP tanks use.

Here is a picture of a 1st stage with a DIN connector... and a yoke adapter in the background. Should be easier to visualize:

Is there any reliable online store that I can get the adaptor eaily? I want to pay by credit card.

Also, one old thread mentioned about the 200 bar adaptor vs. 300 bar. Not very clear, I think one of them is good for different depth. Which one is it... the other thread is no clear, just want to confirm. Most store I talked to only mentioned to me about the 300 bar.

Brand name doesn't matter right? it's just a piece of adaptor, so dive rite, Scubapro, Apeks... all the same, correct?

DIN to Yoke, again is $40?

Finally, safty issue, some mantioned about safty issue, any feedback?

Never say never, I lug my doubles lots of places.

When I don't this...

is a 2-minute install if you take the time to triple check it.



Check the price differences in the initial reg, an adapter pictured above is less than $40, converting a yoke to DIN can run $75+

Scubatoys is popular on the board but isn't the only online retailer.

There are two pressures you care about with connectors. Yoke can operate at up to 232 bar (approx 3350 PSI) while DIN connectors have the option of 232 bar or 300 bar (approx 4350 PSI). While every good manufacturer will overengineer their products, this places a real limit on what you pressure you should use your equipment at. Most shops I've ever seen don't rent high pressure tanks so unless you plan on buying them, you probably don't need 300 bar connectors. That doesn't mean they're a waste if you want to future-proof your purchases. If you can get 232 bar and 300 bar for around the same price, why go with 232?

Some people feel very strongly about the brand, others about the features and others about the price. I'd say the name doesn't matter, especially if it's just the adapter, but I'm sure someone would disagree.

DIN connectors have more contact area with the valve and provide a moe secure seat than yoke connectors do. As such, you will have more problems, typically o-ring, with yoke than with DIN.

I see, thanks. Many dive sites around the world are still using yoke, so if I have a DIN, I need the adaptor (DIN->yoke). Let's say if I use the DIN->yoke adaptor, will the safety level involved be the same as if I am using a yoke 1st stage(no adaptor)? Or would it be worse than that? because now I am introducing more connections, then the adaptor itself also have 0-rings, right?

Quick question:

If the idea is to future proof a reg purchase and your current diving conditions are mostly yoke. What are the advantages/disadvantages of getting a YOKE reg and a DIN kit so you can make the change in the future compared to getting a DIN reg and a DIN to yoke adapter?

Usually DIN to yoke adapters add about 1-2 inches to the length of the first stage reducing the space between the first stage and the back of your neck.
Not that it matters a lot when having proper positioning of the tank in your gear but it just looks bulky.

Assuming you won't be changing from DIN to yoke often, say couple of times a year, (you dive the summer in tropical waters where YOKE is king and then you go back home and dive cold waters where DIN is a better alternative).
Is it a good idea to get just a YOKE reg and buy the DIN kit so you can make the changes when needed (again, i'm assuming you'd need to make the changes a couple of times per year at most).

Is this change something that has to be done by a service technician?

Or is it something you just can do it by yourself?
