Definitely YOKE in Thailand. I was there in February, and at the first day of diving we forgot to notice the club that we have DIN regulators. Luckily some of the tanks had the removable nut and we managed to convert 3 of them to DIN for the first dive (but most of the tanks were YOKE only). For the second dive, we had only 2 convertible tanks, but the hexagonal hole in the nut was of a different size, and we didn't had exactly that hex wrench size.
One of us entered with a borrowed INT regulator, and another one canceled. I also decided initially not to dive (I don't like to use rental equipment), but then I got mad at staying on the boat, and forced the next larger size wrench into the brass hole of the nut with a hammer
, unscrewed it and made a nice solo dive.
