Mine was petroleum engineering with minors in geophysics and geology, math up
through diffy-Q and linear algebra. So were close. Ill concede that point

Why would one USE trimix in 30 - 60 '???? Sure it can be done, but you cna also
go deer hunting with nuclear weapons, It would work, but it just isnt
practical.

I concede this also. Frankly I think nitrox 32 should be worked intot he OW
course with the simple admonishment - GO NO DEEPER THAN 130'!!! My concern is
that helium adds alot more complexity, Deeper means more potential for danger
in terms of DCS, ascent speeds, etc... I think that the long road to trimix is
there for the safety of the divers, to keep newbies form doing the doria the
day after their checkout. Practice, and ALOT of it, should be the prerequisite
for mix. A course has to eb designed to be suitible for the lowest common
