Ok, Ok, I'm not knocking the Nemesis Nitrox.  I like it's programmability.
But I just don't find it sufficient, I'll never count on it completely 
on a serious dive.  Because *EVER* going into a "guage" mode is too 
often.  When I mentioned it happening to me, as I recall, I said it
happened after it transitioned through a 40 ft ceiling.  I understand
that it says that in the manual, and was expecting it.  It is still a 
good thing that I had already worked out a schedule for my dive, and
was also using the Alladin.

My experimentation with it is deliberate.  I just bought it, and only
have about 15 dives on it.  Serious dives with bad surprises where 
deviations from plan are where computers come in most handy, by my way
of thinking.  They give additional input that let me make decisions 
during the dive about ascents, profile and everything else.  So, a computer
that will go into guage mode is not really cool by my way of thinking.
