About three years ago I argued with Jammer. Now I know
he's right. 

I have NEVER dived a mix I haven't personally analysed. 
Other than air. I have never relied on a label or a sticker.

A buddy I dived with used to let me fill and test his gas
and deliver his cylinders to the carpark where we kitted
up for the boat. I did it for him because I trust me. But 
I never allowed him to return the favour.

My sling cylinders have nitrox stickers on them because
they sometimes go into hire or lay around the dive shop
and I only want them filled from the nitrox panel.
 
They have tags on them that *I* write the date, mix and 
depth on - so I can check up on myself. They also have MOD 
on a big piece of tape that sits a foot from my face when
I'm wearing 'em.

My back cylinders are unmarked. I can't see anyone climbing
into that rig accidentally or presuming it contains only air.
*I* write the mix and date on a little piece of tape stuck to 
one of the cylinders so I can double check it myself.

Yep. Jammer's right. You need more than a label to tell you 
what's in a cylinder.

Here's a concept: The only gas I take on trust is air - 
which comes in unmarked, unidentified cylinders.

bless you all the way
