Multiple gas mixtures do cause problems with dive computers, that's why
the big boys dive multiple computers, but multiple gas computers are
coming on to the market Cochran builds one and sunto is rumored to have
one by the fall. So I think eventually the computers will begin catching
up with the divers. For now I prefer the BT and my tables.
