It is a MK-2, and it isn't old...

Unbalanced piston first stage. Simple and robust.

It is my "stranded on a desert island" first stage choice....

I use them on my pony bottles, redundant supply for ice diving, and for DECO bottles.
 
Thanks! My dive shop owner wasn't sure.

Any suggestions on a good match for a 2nd stage for a solid deco setup?

Before I read @herman post, I was also wondering about the LDS owner. He or she most be new to diving. :confused:

This 1st stage has changed a little bit since it was introduced around 1965 or so. You can now get it in DIN and they added that black rubber open boot.

Turns out the newest EVO’s have a replicable orifice! Now they should last double forever.
