Yoke sure seems to be an odd design. With DIN the o-ring is quite captured and the 1st stage is lighter and more compact.

very true and the tank is a lot nicer. It's mostly recreational diving so either way would be fine. I'll probably convert it. Does anyone know of any good site to buy conversions for a scubapro MK25?
Or if you would like to save money (or make some money) you can just buy a new yolk valve for you cylinder and sell the din valve for just as much or more than you bought the yolk valve for. Plus you can still use your regulator on other cylinders that have yolk(and most do .....at least in the states.)
Ace I was think about that but the guy at the LDS said o rings blow out all the time with the extra pressure and it's bad for the reg. Don't know if that's true, any opinions?
Here is my take, If you got a good deal sell it and get a low pressure tank if you boat dive a lot. If it is a 3500 psi tank you have to find some one to slow fill to that psi. If the tank is a 100 filled to 3250psi cold then you are 10% short or 90qft or only 10 more qft than an 80. Also it is impossible to get a boat to pump that high on a fast fill you will be lucky to get 3000psi! So if you do this kind of California diving the sell it and by a low pressure 2400psa 105qft. filled to 3000psi, which anyone can do even a boat, it cools to 2800psi you are almost 20% above 105qft or about 125qft of air! One and half times that of an 80! Then you can really impress your friends on those 2.5hr dives! So I say sell it! and buy another tank!

Sorry, maybe i've got the wrong end of the stick here but, to convert a DIN valve to take yoke - otherwise known as A clamp- regs merely requires a small adapter that just screws into the DIN valve ? The result is exactly the same as a normal yoke configuration. It is the other way around that requires the addition of a large and expensive adapter that increase the size of the whole 1st stage assembly.
Personally, I've got DIN valves and regs. the main advantages for me are: only one O ring required no matter how many cylinders i'm using over the day, a much more secure fitting, absolutely no danger of knocking it off passing through a tight space etc. The only possible disadvantages are: possible incompatability issues with Yoke valves when travelling, the possibility of jamming the reg into the valve if you hit it hard enough when passing through a tight space.

Today is a good day to Dive.
Rings blow and bad for teg
That is correct. O-Rings blow and the wear and tear on the Reg with High Pressure.Originally Posted by hbh2oguard
Look at what you are trying to accomplish, is is "time", is it "Safety" is it ...
"etc..." and go with that.
I prefer DIN personally and carry the converter when traveling.

I really like Papa Bear's idea, but you may not. As far as it being bad for your regulator, it has nothing to do with the valve, but to do with the higher pressure.
You have more than a few choices here on what you can do, so now the bottom line is up to you.
Oh, that just begs for a rhyme rendition:You have more than a few choices here on what you can do, so now the bottom line is up to you.
A yoke can blow that dried up o-ring
Without a spare, you'll feel the sting
You may throw the old yoke, in the bin,
And come up to date, with the DIN
You've now got more choices, on what to do,
So the bottom line, it's up to you
Ok, so I just woke up this a.m.
I have several things to say, while I am stuck on land due to bad seas and not able to dive, GARBAGE, GARBAGE GARBAGE!!!!!! That is truly the most idiotic thing I have heard in a while! These are high pressure regs to begin with. 3000 psi. is high pressure, 500 psi. is not extra higher pressure. (What is this super secret double probation? [Animal House reference]). The regulator, provided it is serviced annually (per manf. specs.), is designed, and capable of handling this and higher pressures. I have been diving DIN regulators, Mares and Scubapro, for 12 or 13 years and servicing them for longer. The only regs that show unusual wear, are the ones that are not serviced regularly! This is all a function of maintaining the correct Intermediate pressure on the first stage.
That is yoke or DIN.
The profile of a Din is smaller and less obtrusive and less prone to failures. The O-ring on the yoke is exposed to all and wears out much quicker than a DIN O-ring (which is mounted on the regulator itself)
Now if the tank is to your liking and the valve is not, you can sell the valve, buy a "standard" valve as a replacement. This is a store/site that could help you. http://www.diveriteexpress.com/gas/thermo.shtml
It has the added benefit of being able "convert" back and forth, should you so choose. The other consideration, as Papabear indicated, is the ability to get a "true" fill of your HP tank. Here in Florida, and especially in cave country, a good fill is readily available.
I have L.P. tanks (2640 & 2100 psi. working pressure), I have H.P. tanks (3442 psi. working pressure), I have standard tanks (3000 psi. working pressure). They each have their purpose, and are dove in certain combinations and/or situations. What is not changing, are my regulators!
What it boils down to is simply this, what diving are you going to do? What should not be a factoring consideration is whether or not your regulators can handle the various pressures. They can, how about you?
