Gas testing and sidemount

[Kelly Jessop]

With more sidemounting and nonmanifolded tanks being filled,what does everyone do for testing?

[Sludge]

I don't understand the question - are you talking about analyzing the oxygen percentage of nitrox?

If I dived a cylinder that I didn't analyze right before the dive, and my instructor found out, he'd kick my head.

I think he is asking if you would only check one of two sidemonut tanks. I wouldn't, unless hey had been conneced together for long enough to equalze the mix, which would be quite awhile. Even worse, not checking because you used banked nitrox. Actually, if you bother to get the analyzer out, it doesn't take much longer to check them both.

Yup - LCF posted something over on TDS recently about a good instructor staying with you as kind of a secondary conscience. I don't breathe anything I haven't tested.

Ichech each independent tank with my O2 and or Helium analyers

[Neptuno]

well, no need to analyze the air down here, if we did for sure we can get enough oil out from it to supply KFC if there is something other than air will analyze both/all tanks

I have a (true) story I tell my MBA's. A guy I know was just starting a new marketing research company. One of his first gigs was to collect data for a toothpaste company on tooth brushing habits. He employed a bunch of undergrads who went out and surveyed people exiting a supermarket.

Apparently EVERYONE surveyed brushed three times a day. If one forecast forward from the numbers, toothpaste consumption would have been double what it actually was in the area.

Anyone see the parallel?

let me put it another way - I've seen an awfully large number of people leave fill stations without testing their nitrox.

27:1? Really?

Too funny!

[Sludge]

If my instructor had been their dentist they WOULD brush three times a day!

[jlillest]

I dive SM, get air fills, don't test my tanks and brush 17 times a day!

(although when I had access to a multi-gas monitor, I would check my fills from a certain buddys gas compressor occasionally for CO content)

Leaving the fill station without testing gas is probably not a determinant of gas testing being done. I routinely test my gas in other locations,and depend on my O2 tester because I know how it was calibrated,stored etc.

I had overheard a discussion about how if one sidemount tank came up a certain percent,then the other one was the same,so why bother testing. Things have changed over the years,but once I had my sidemount tanks filled,and one tank was filled by a nitrox whip,but the other was an air whip-I was thankful I test everything. Old habits die hard,and I was trained to test everything,and that includes plain air.
