I just read in an article that a disadvantage is that it increases your "dead air" space--that is, there is more air that does not get recirculated, since there is a larger volume of air inside the snorkel. Has anybody experienced a problem like this? What kind of tradeoff is this? After all, it would be less tiring to have an easy draw of air. I think I would rather have to take 10 easy breaths than 8 restricted breaths for the same amount of oxygen, but I have never tried the wide-bore style. I wouldn't like to black out from lack of oxygen (or turn blue in the face) --John Carey -- {ihnp4,convex,pur-ee}!uiucdcs!carey carey%uiuc@csnet-relay.arpa carey@CS.UIUC.EDU
