We are talking the entry level nitrox that the recreational agencies are
teaching? If so, based on diving philosophy as it stands now, OW training
should be integral so an instructor can evaluate how the person is actually
planning the dive. Many divers are taking nitrox right out of OW, so
Mickey's comment may have been valid in 1993 when nitrox was considered
voodoo gas, but not today.

A student needs to see real world dive planning as well as what they do in
the classroom. Also, as was mentioned they need to see the different
analyzers and how they are used. My gut feeling is that w/o and instructor
present in their initial exposure to breathing nitrox a student will resort
to computer dive planning (my computer has not beeped so I must be OK)

Now, a technical diving aspirant needs more classroom time, and that's why
the SCUBA agencies created classes like Tech nitrox, Advanced Nitrox, Deco
Techniques etc. That should also require OW dives as the skill set required
is more complex.
