To support your statement, I had a frozen inflator in 6°C water; in my case, it was nothing serious (the frozen inflator was filling the wing relatively slowly, and I had managed to disconnect it very quickly), but the water was 6°C (that is, relatively warm with respect to the context we are discussing)... At lower temperatures, I am sure everything happens faster and more seriously (we don't need a degree in physics to understand it).
Cold has to be taken seriously.
Are you saying that some people actually teach to go ice diving without lines?
i cant confirm this.....but i recall hearing that they dive without lines in Antartica.....
regarding the inflators....that is a very real problem...i dive with mine disconnected....when going through training, we had a few people who had theirs freeze open, fortunately they were very shallow when theirs froze, and they hadnt gone under the ice yet....but even "cold water" equipment struggles when the water is near freezing temperatures.
