Just wondering when they where last calibrated is all. I do that type of work. Medical gas analysing.

Not sure on theirs, mine was calibrated for all gases in Oct-13. It's certainly possible theirs isn't calibrated correctly, but it's partial pressure blending, so the 50% is blended based on volume and the pure O2 'should' be as simple as cleaned and filled straight from a G.

What would happen if you didn't test them and then used them?

If I had assumed they were 50 and 100 and cut my dive plan accordingly I would end my decompression stops still nitrogen saturated and probably (although not guaranteed) to end up with decompression sickness ie the bends.

Knowing that they are 40 and 80 means I have to recut my plans and it extends my deco stops due to slower nitrogen offgassing. It's not a huge problem by itself, but as I've planned multiple deep dives (+50m) using these gases, means longer time on these gases, resulting in less gas overall, and I don't like starting my deco stops with already less than half full tanks, which now I will.

the oxy we use is 100% medical grade from boc gases at 9m, but i think thats purchased with permits.

I've said it before, I'm really surprised you guys are using O2 at 9 metres. At 6m you've hit 1.6 bar which is O2's MOD, and anything deeper dramatically increases risk of oxygen toxicity. Are you ADAS or Aqua? Curious to whether it's industry standard practice, although I know for a fact that SAT won't let you get away with it.

And also out of curiosity, what's an average depth/time? Interesting to see, if you don't mind me asking.

You would be correct. The Bane of "all Telco's using Telstra infrastructure" existence.

Yup, couldn't agree more.
Having a freshly build network (ie NBN) would make life a hell of a lot easier!

Wondered why the weeds coming through the pavers in the patio haven't died after spraying them 3 times.
Misses kindly pointed out that I've been spraying them with Insect Defender...
