Nitrox at BuddyDive

Hey guys,

We are planning a trip to Bonaire mid-December. I may add the Nitrox
option. Just wondering if (a) their fills are reasonably accurate, (b)
it's fairly convenient to get your Nitrox tanks, and (c) if they have
an analyzer available, or one must bring one's own (okay, I confess I
still don't have my own ... do I need to buy one to dive
safely/conveniently on EAN at BuddyDive?)

Tanks,
-Chris-

If you don't trust 'em to get the mix right, why would you trust 'em to
keep their analyzer working right? <g> You're the one diving the mix;
you owe it to yourself to make sure you know what it is.

Good question, and is the same one I asked myself just before I got my
own analyser.

Filling accuracy has nothing to do with it. Even you ger "EAN32", it is
always between 31-33% and it is your OBLIGATION to make your own
measurement and DO NOT RELAY on the measurement made by them. If they
don't provide you an analyser, or object or show big surprise if you
request it, such simply don't use their gas, because they are not
reliable. Haven't you been taught this on your Nitrox course?

I would like to add even more: you should make a measurement just before
the dive. Especially in case of many divers on the boat, some of them
using air, some Nitrox, some custom mixes, you should not accept a
common practice, which is to measure the gas in the base, than put a
tape or tak on the bottle. This is may be good, in case you have your
own bottles, which are unique and can not be mixed up, but not in case
you rent the bottle from the center, because usually they have all the
same. You should request an analyser to be on the boat and check the gas
AFTER you have your jacket already fixed to the bottle. Only in such
case you can be sure what you breathe.


(b)

If they don't have one, they can't make any mix. If than they offer
something other than air, you shouldn't use any of their gas, because
you may get anything from 21-100% O2 in the tank and you will never know
what do you have.

or one must bring one's own
It must be in the base if they provide Nitrox. If they don't have it -
don't dive with them.

If you have a few millions to spare, I can give you my account number :D
You can have your own of course, but it is not mandatory. It is a simple
(even primitive) device, which you can make even by yourself. If you are
prudent, you should check only how old the sensor is - generally it can
stand not much more than one year of usage (I think some can be used max
2 years, but use max 1 year as a benchmark).

Can you explain why this is the case? Does the air separate in the
tank? The curious need to know.

No, he can't.

Cattle don't understand nitrox.

Well, there's a possibility that if the tank was filled just before you
measured it the gas might not have mixed completely, so by waiting you
get a better number. Of course, you're supposed to allow for that in the
first place, and not measure tanks that have just been filled by partial
pressure. It sounds more like the idea is to eliminate the risk that
someone switched your label to a different tank.

We're very proud.

What? Perhaps you should learn a few gas law. Gases don't behave
like liquids. There's no mixing time. I actually cured one shop
monkey of rolling tanks by having him take a measurement immediately
after a fill and after "mixing up" the gases. Guess what happened.
