I can tell that there are lot's of other regulators which also blow bits of ice when diving in a really cold environment. This effect is not always harmless. I have been diving with the classic Scubapro Mark V and had got high velocity bits. Although the first stage was covered with 1 cm layer of ice when that dive ended. This was not a very typical dive. Many of my friends with different kind of regulators get bits also, not unusual at all. Sometimes when you dive deep and cold, the forming of ice can be so fast that the bits fly fast into your throat which does not feel nice. As far as I know the worst situation occurs when your first stage has just been frozen and the regulator is free flowing. While surfacing the rate of ice hits can be very high and it can make your breathing difficult. Greetings from the cold Scandinavian waters, Turku, Finland Terho Kaikuranta
