using "hand-held" type O2 analyzers for deco mixes

[mderrick]

So at what point should one get an expedition grade analyzer? Trimix? Advanced Trimix? When one starts to push even deeper?

Well, one rule of thumb I heard was when the total cost of the gas fills for the dive is approaching the cost of the analyzer used to check them, it's time spring for a better analyzer.

Well I got a ways to go I think I paid $200 for my Palm O2, with my average dive being $15-20 in nitrox, and $5-10 in oxygen (if used).

Unless you're in the doing saturation dives, in navy research, or doing something stupid like doc deep. Never. Its a bunch of marketing hooey. You don't need it. The analyzer is only there to confirm what you already know because you calculated the mix correctly in the first place.

That is a VERY easy rule to break nowadays.
