Subject: RE: DIN on deco stage ?

I seen two arguments on this list:

1.	"I have such an investment in A-clamps that it is not economic to
replace with DIN."
2.	A-clamps are easier to remove than DIN should you ever need to switch
a stage regulator underwater.

The reality is that a stage can be controlled by the valve and this is
switched off when not in use.  However, an A-clamp remains less reliable than
DIN and slightly more damage and nag prone.

All my regs are DIN, but I would not have a problem diving an A-clamp stage.

Subject:	DIN on deco stage ?

Hello,

After a lot of reading and even watching the DIR II tape. There is still a
point which is not so
clear for me. All the examples I have seen for deco tanks have used Yoke
Valves and Regs.

I am wondering why they don't use a DIN valve and reg like the back gas.

Is there any particular reason DIN is not mandatory ?
