I dive DIN at home, but usually have to use an adapter when on vacation. I did run across adaptable tanks in Mexico last week and was pleasantly surprised. What y'all are saying about threads and damage does make sense.

I guess this has to do with the longevity of rental equipment? It's pretty hard to damage a yoke... but the DIN screw-threads on the cylinder valve or regulator only take a klutz to destroy...
With DIN everyone is running in and out of threads. When you have Tom Dick and Harry using the same tank a lot of wear takes place. Some folks are real klutzs when it comes to matting threads. Even the use of beat up fill station whips can haunt your valve and then you regulator connector. A yoke connection is a clean face mating and it's transparent from user to user.
Sand or grit in a DIN connector is no fun. Yoke is more forgiving where this is an issue, hopefully never but crap happens.
A DIN connector's swivel stem can break free especially if distubed before pressurizing.
If you rinse a yoke connection before breaking it free the other critical surfaces are clean ad dry. DIN connectors and valves require periodic thread cleaning since they are exposed to the salt when in the ocean. This goes back to the first point where ow we have saly encrusted threads mating again and again.
I agree that DIN is a more positive connector. However don't kid yourself into believing that it is a panacea and yoke users are fools. Yoke is much more amenable to transient resort users.

PS, I use both.
I keep hearing the busted up threads/falling over tanks busting up tanks/1st stage arguments a lot, yet Im yet to see it and I do dive a fair bit in locations where the standard setup is din with yoke insert 1st stages..I guess this has to do with the longevity of rental equipment? It's pretty hard to damage a yoke... but the DIN screw-threads on the cylinder valve or regulator only take a klutz to destroy...
... Maybe american divers are more adept at busting up- DIN valves/1st stages than european divers?
Dumb question I assume but you are talking about DIN right? Forgive me, I have never used DIN.Most divers insist on cranking their regs when attaching to the the tank which results in many many cut O-rings. Not a huge, huge cost, but a cost all the same.
