On our dives in Cozumel it is common for different pairs to come up at different times and in different places. Nice and safe to say "Just follow the DM" but that is not reality with some dive ops and some divers. And it is never a sure thing, regardless.

Working on a computer system for a kiln I had 16 (I believe) thermocouples feeding back to a PLC. It irritated me that they all read different readings in testing so I wrote a routine so that I could put them all tightly together and insulate the bundle to bring them all to the same temperature...

Yes. But I think the boats long term Scubaboard members dive with probably carry a higher percentage of nitrox tanks. The boats that look like buses probably carry less nitrox. But I am confident that AICO pumps a lot more air than nitrox.

I'm an all-in nitrox guy, but my experience with one of the tank fill op on the island tells me a lot more air is filled than nitrox.

Great lady, I like her.

I believe her dad was Arabic and her mom Israeli. Grew up going to a Catholic school in Cozumel.

Hi Kimela, Did Dr. Yasmin ever tell you about her background?

Do you really think large compressors have higher per tank costs than small ones? I've never seen a fill shop put in a whole bunch of small ones to save money.

I have a small compressor and have experience with the costs. That being said I am a friend of a guy who fills tanks in Cozumel. I understand that his labor costs are low, but I suspect his filter and oil and parts costs are high. I know for a fact that his electricity costs are high. I am...

He admitted to being a banned sock puppet. I'm sure he was already back with a different face on the puppet.

I could dive Cedral every day.

Well, then that is that!

Multi-dive oxygen toxicity and exceeding MOD seizures are very different things. Go find or steal a copy of "The Oxygen Hackers Companion"

Please map out 5 Cozumel dives over a day under 96 feet and tell me how you could exceed the allowable limits. I might mention that deco divers routinely exceed these limits with impunity. Edit: Years ago I studied this when I started mixing my own nitrox. After careful study I understood that...

Can you explain to us how he could be in danger breathing nitrox from a membrane as air while staying above 96 feet?

I don't know. I always doubted it since I was told that. But I have seen several valves that were not tight to open seize open after a dive and when they finally moved off of full open they were smooth again. It has made me go back to reversing my valve slightly after opening it.

If you turn it wide open against the stop and the shaft in the valve shrinks from temperature drop it gets really tight, apparently. I never believed it, but I've seen something happen that makes an easy turning valve not turn at the end of a dive. As soon as it comes off the stop it turns...

Trouble is that the valves were not hard to open and were not hard to shut, after I got them to turn in the off direction.

It was explained to me that the cooling of the mechanism with the air going through it would shrink the stem and bind it. I suspect that this sometimes happens.

I've been diving 40 years and was taught the 1/4 turn rule. I did not believe it and have always turned my tanks on all the way. For some reason several times in Mexico we have ended up with tank valves stuck in the open position after a dive. I am trying to remember to turn them back a quarter now.
