Wrolf, how many mix dives have you done? Don't be a jackass, 130END is farm animal stupid for this dive, and probably for any other dive, for that matter. I liked it better when you were gone.

If you want the formulae, then you could either visit Jim Cobb's Trimix site, or check out Tom Mount's book. References for either are on my site. -- Wrolf wrolf@wr*.ne* Wrolf's Wreck: <<http://wrolf.net>http://wrolf.net Wrolf's Net.Wreck: <<http://wrolf.net/netmgmt.shtml>http://wrolf.net/netmgmt.shtml </excerpt><<<<<<<< ------------------------------------ Kevin Connell <<kevin@nw*.co*> NW Labor Systems http://www.nwls.com "I suppose you want a user interface with that.." ------------------------------------- -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
