    Hi, a quick question for some experienced people,

    I understand that an environmentally sealed 1stage is requires for cold water diving. Would I be right to assume that a sealed 1st stage could also be used in warm water with no issues?

    It's not 'environmentally sealed' that matters per se, it's the cold water design which counts.

    Compare two renowned first stages: Scubapro Mk25 and the Apeks DS4. Both are excellent cold water regulators, the Apeks is sealed and the Mk25 is open.

    All cold water regulators can be used in warm water. Warm water rated regulators have inferior icing resistance, e.g. they don't have heat sinks or are made out of plastic.
