Ted It doesn't have so much to do with the money as it does the fact that there are those of us who do not want to have to take a deep air course just to dive Trimix. So tell you what you fill my tanks with Trimix, here where I live, without me being certified Trimix and I won't mix my own. By the way there are no shops in my are that do Trimix. Also anyone smart enough to set up their own mix station is smart enough to know they can build an O2 analyzer for $100 and probably already have. sean > -----Original Message----- > From: Ted Green [SMTP:scuba@md*.co*] > Sent: Friday, October 10, 1997 7:16 AM > To: Kevin Connell > Cc: techdiver@aquanaut.com > Subject: Re: Internet guide to Trimix > > > From: Kevin Connell <kevin@nw*.co*> > > > Ted - What is the liability in topping of a trimix?
