Subject: Cheap And Nasty Snorkel extension
From: "Don White"

I've wondered about the small bottles of compressed air complete with a
mouthpiece that emergency crews might carry.
Not sure if they are for 'fire' use or to revive a patient.
Could they be used for Lloyd's application?


Perhaps, but there are so expensive (about $200

and they hold so little gas that you would be better off getting a "real" scuba
rig.

Capt. Bill

Wow! Is that 200 'merican dollars??
Probably not a big deal to Lloyd but a bit much for a poor Maritimer :-)

GA but the water is pressing on a couple thousand square inches of
lung
GA surface.

The real problem is the "dead volume" in your snorkel. You will be
inhaling your own breath over and over again.

L No, the real problem is just as Glenn has stated.

Maybe. People have tried longer snorkels before and died from it.
That's a real problem in my book.
