"INCREASE INTERMEDIATE PRESSURE WITH DEPTH"

I thought this was the function of any regulator to prevent you from getting
your tongue sucked into the reg (see 3ft snorkel scenario). :-)

Could you clarify this for me? Do you mean that the design is supposed to
increase the intermediate pressure beyond the water pressure when you get past
a certain depth (presumably to give better performance at deeper depths) or is
it something else.

I would agree that Sherwood regulators are not prone to freeze up.  The Dacor 
Extreem, on the other hand, is one of the worst designs I have ever seen for 
cold water.  It is designed to automatically INCREASE INTERMEDIATE PRESSURE 
WITH DEPTH.  That causes a slight freeflow and often results in a freeze up.  
As for what Mike Zee allows - I dove with him on his boat last year and used 
my usual rig which includes two Scubapro MK14's for my primaries and Scubapro 
MK2's for my stages.  BTW, I have never been able to make my Scubapro MK14's 
freeflow or ice up, nor have I ever seen anyone else freeze one of these 
regulators.

Good diving,
Dale
