I'm headed for Cozumel this PM so I better get my 2 cents in now.

I doubt if there is a regulator made that will not safely handle uneventful recreational diving. I also doubt if there are any that can not be overbreathed if a diver overexerts himself.

I think you're wrong. I just have to swim hard on the surface in California waters on my back and I can feel the resistance of breathing off my regulator, and easier breathing when breathing ambient air. And if I can feel the resistance on the surface, it's bound to happen at depth.

Addendum: Sorry I misread your post. I agree.

I dive mostly 30 to 40 year old Scubapro regs; Mk5/7/10 with 109 & 156 2nds. Bought used. Most expensive setup was $150. I also use a Mk2 with G500 or R380 on my pony.

and I don't think anyone who knows anything is going to call those regs unsafe, either.

Still waiting for a current example of an unsafe reg.

Awap said the same
 
I'd much rather have a regulator fail during a dive than a tire fail as I drive down the interstate. Does that mean my cars tires are life support equipment?

Huh? :confused: I beg to differ. My grandmother can pull off the side of the road.
 
I'm confused. Is there a debate over whether a regulator is life-support equipment? I can understand the argument over how much importance a person chooses to give a regulator in making any one particular decision or argument. But I can't see how the argument that a regulator is not life-support equipment can be made. Maybe it's just a difference in how someone chooses to define life-support equipment?! To me it seems clear-cut. The human body requires oxygen to sustain life. A regulator is a primary device that is part of the system that delivers that oxygen in an environment where no other means of getting that oxygen is available. This makes it life-support equipment. What am I missing?

Seems clear cut to me as well...

I concur on the first statement. The second? :idk:

I would have to guess there have been many/few that have been pulled from the market and disappeared from divers bags before too long without much drama. DAquamaster might know...
