Here we go again. One more time...

Wear a set of doubles, breath a stage of mix. There. 
That's cut your gas costs in half.

Then, when you get down to diving the back-gas, blow 
it back with air a couple of times and you get two 
more, clear-headed dives out of it, though not as deep 
as the first one.

By the way, it costs me $190 for the trimix and deco 
gas to do one dive on our 70+ metre wrecks.

And again: Fill your doubles with mix, and take 
a number of stages filled with mix. On each dive, 
carry a stage of mix. Breath the stage, leave the 
back-gas for contingencies.

Next dive, carry a stage of mix, breath the stage, 
leave the back gas for contingencies.

Finally, last dive of the trip, don't carry a stage 
of mix, just breath the backgas.

Finally, when you can get to a compressor, top up
the back gas with air and you've got a mix that will
give you a couple more shallower but clear-headed 
dives.

Hugo, no-one is FORCING you to dive 60+ metres on air.
Or to do it every day. You are CHOOSING to. You are 
also subjecting yourself to neurological and micro-
ciculatory damage each time you dive deep on air.

I have show you how to dive more cheaply on trimix. If
the result is still too expensive, then maybe you simply 
can't afford to dive deep as often as you would like.

In the meantime, you are teaching and encouraging others 
to dive deep on air.

     Now ten years later, I'm still a sportsdiver, learning 
about DIR, Nitrox, Trimix, redundancy and lots of other stuff.
Finding out that there are still people, who made diving their
proffession/living, defending and teaching the same stupidity 
that already killed people in the last ten years of diving and 
will continue to do so untill they stop.
     This again makes me sad, so lets stop them.......because 
they don't care:
