But if the required and adequate arrangements are made before diving in the freezing water, one can easily dive without a problem as some one said it rightly it not the told water that spoils the fun but being cold is.
So, once you tackle this cold problem you are good go.
Why so?
because under freezing water, the low temperature makes the gas in the cylinder to freeze.
the ice forms in the internal working apparatus of the regulator which causes it to be cloaked by the ice and so it doesn’t work properly.
So, for that matter one needs a special kind of cold regulators which is environmentally sealed to avoid contact between the cold water and internal apparatus, composed of metal steal stage to provide more thermal conductivity which retains heat.
Sounds complex? Still confused? Let me make it easy for you. Here is the list of top 10 regulators I recommend for cold water below 40 F.
