Thoughts on MK25 EVO/S620Ti for me

[BoxJelly]

One last post and off I go. It is cheaper to buy Int and then buy the DIN kit. It takes me about 5 minutes to swap between the two. I never see a reverse kit available to go from DIN to Int. But I can get the DIN conversion kit cheap on Amazon. Those Int converters basically suck IMO. The "dust" cap that Scubapro currently provides is the same piece for DIN and yoke, it is universal.

Interesting. I was watching this video and it explains that adapting a DIN reg to a Yoke tank is much easier than the reverse situation.

Scuba.com has DIN and YOKE for the same price. As for adapters, the DGX conversion kit is $25 and a rubber dust cap $2. It's just a piece of metal and some rubber, so I don't really see the point in getting an adapter from the OEM at a 150% markup when the specs say it's the exact same material.

Converting from DIN to yoke is easier for them because they are using those horrid and failure prone adapters. Again, Scubapro sells the genuine yoke to DIN kit. I have not seen a DIN to yoke kit. Other than an adapter, which, well, I find them unacceptable.

The only thing I would do with the DIN to yoke adapter is toss it far into the ocean, without me attached to it. I would use the correct parts to make the conversion in either direction, not adapters.

If you will never use yoke but maybe once or twice in your life then I suppose an adapter might suffice for once or twice for a dive. I guess we over here may have a different perspective because most rental and resort tanks in the Caribbean are yoke and those that are convertible the inserts are often frozen in place.

Genuine Scubapro yoke to DIN below. There is no such kit I can find going the reverse.

Ohhhhh I am starting to understand now what you mean by converter vs adapter (rookie mistake by me I guess).

So buying a YOKE first stage, and applying a DIN conversion kit = a DIN first stage. Whereas buying DIN first stage, you can only use an adapter to change to YOKE, which introduces more points of failure to a traditional YOKE first stage. So going YOKE and buying conversion kit is best of both worlds. Is that right?

Once you apply the conversion to a YOKE, is the converted first stage able to handle the higher pressure levels a DIN first stage can?

The greatest issue with din + yoke adapter is that it sticks out a couple of extra cm and probably bumps the back of your head. @lexvil posted a photo comparing the yoke vs din + yoke adopter side by side in

Thoughts on MK25 EVO/S620Ti for me (not sure if linking to specific post works).
Note that using the conversion kit needs unscrewing the yoke with a big spanner, and installing the din part with an Allen key with appropriate torque (30 Nm = 266 lb.in = tight if you’re not using a torque wrench). It’s not difficult but you need tools (unlike the adapter). If you’re not comfortable doing it yourself it should take a dive shop technician less than 5 min. They may or may not charge you for it (likely not if you’re buying something from them).

Yes, that is what I was saying. Really, if you are only going to use a yoke adapter a few times it will probably work out. I hate them for various reasons, the yoke adapters basically eliminate the good of either system and amplify the worst of both.

There is no difference between a DIN and a yoke Scubapro first stage or any I know of currently produced. One kit screws out and the other then screws in. Scubapro uses the same "dust" cap for both DIN and yoke.

Here is a Mark 2 which uses the same Universal DIN kit, notice that the only difference is those parts specific to DIN or yoke, for example:



I have made the conversions going both ways on a liveaboard in the Red Sea and many a resort room or sitting on the tailgate of my Toyota. It is pretty simple, kind of like throwing rocks, most members of the taxonomic tribe of Hominini could accomplish the task with minimal training and a few rocks.

@Nemrod do you have a video that explains how to do the conversion for ScubaPro? I can find one for Apeks, but am trying to find a SP-specific one. Want to gauge if I can get comfortable doing the conversion myself.

Also can you list what tools I will need. Ideally lighter versions for travel.

Great choice of reg (there’s plenty of other great choices too*, which no doubt will be suggested). Since you’re behind the tariff curtain you might consider purchasing when on holiday.
*FWIW I like diaphragm regs for tolerating a broader range of conditions, and would go for MK17 Evo 2 with G260. But that’s just me. Other brands are good too!

Going with DIN or yoke first stage? I'm wondering if I want to go to DIN.

I think Joe just posted the ScubaPro adapter youtube just before I sent this. Seems like that would solve any questions on which way to go.

This type of pliers can work in place of the socket. Smooth jaws and the grip increases with your grip. A handle to screw into the HP port. A set of quality allen wrenches or the socket from scubatools and some drivers for the Allen screws.

As to torque wrenches, being a professional A&P for some years, I have turned enough wrenches to know my torques pretty good but of course for a customer regulator I would use a torque wrench. For me, on a live aboard or the tailgate of my Toyota, My hands and the Knipex parallel jaw plier is enough or a set of Allen drivers and the aforementioned socket.

1" Yoke Nut Socket

Yoke Nut Sockets At Scuba Tools, we manufacture two custom yoke nut sockets and a custom 3/8" drive extension. These tools allow the technician to accurately torque yoke nuts on most first stages.The sockets are available in two sizes: 1 inch and 26 mm. Both sockets are manufactured...
