Nitrox Tank Marking

Cozumel

Now that I think of it, I believe I have heard in the past that some dive operators in Cozumel do indeed show up with your nitrox loaded on the boat and no way to analyze. Personally, I would not stand for it.

One we dove with has an analyzer but seems surprised when someone wants to use it. We carry our own. Another one we dove with on the mainland was really excited to see ours so they could check theirs. I think I own 4 or 5 working analyzers and if I had a dive shop I might have more.

Good to know. So is the recommendation then to carry your own analyzer if you plan to rent tanks abroad, just in case this scenario occurs? I compare this to having DIN regulators and carrying a yoke adapter in case a dive op does not have DIN valve tanks, although the gas analysis on EAN is far more important to do due diligence on. If you don't have a yoke adapter for DIN regs, you don't have many options. At the end of the day, you don't want your plans messed up because you didn't plan for every contingency.

This is a very rare occurrence. If you don't want to go to the expense of owning your own analyzer, try contacting the operator you plan to use and asking if you will be able to analyze your tanks when you get them. If they won't do that, go with a different operator. There are plenty of good ones there.

Good call. Thanks!

No, at no point do I have to trust the dive shop. No one should trust a dive shop when it comes to this stuff.

A mistake can equal dcs, oxygen toxicity, or worse.

Analyze your gas, guys. Get it together.

Anyone who thinks they don’t need to analyze their tanks is playing Russian roulette. Accidents can and will happen if you take the “trust me” approach to your breathing gasses. Don’t believe me?? Read this:

The Rules Apply to All of Us

If you don’t analyze your gas before you dive, stay the hell away from me. I want no part of a body recovery.

Yes, of course, and I do. But I am referring to the millions of new or otherwise recreational divers who rent tanks or dive resort boats? they are not analyzing. They do not own an analyzer and they are not going to ask the dive shop to borrow one, they wouldn't even know how to use it. I don't believe it is necessary for them to analyze.

If they are certified EAN they should know how to analyze them. Also, the dive shop should have a log that they sign as a part of that analysis process.

“At some point you have to trust the dive shop”

That’s some of the worst advice I’ve read on SB

I was in Bali, diving out out of a “reputable” dive shop. We got to the site and they handed me a tank with tape on it sayin “32%”. I asked for the analyser and they said “its back at the shop but it’s fine we have already analysed it for you”. Long story short I refused to dive gas I hadnt analysed and they brought me the analyser. It read 43%... let’s not trust the dive shop.

You're right! don't do that.

Not all ops in Coz do it that way. I dove with Dive Paradise last June and got nitrox. Although there was no log to fill out they provided an analyzer for everyone to use. I preferred using my cootwo since it also checks for CO.

Kind of seems like a crummy op if they can't provide an analyzer for the boat. I think merry-d does the nitrox fills so pretty much every op on the island should have nitrox as an option. It's just a question of the boat having an analyzer for their customers or not.

I'm thinking the shop log is more about lawsuits than anything else. Probably not an issue in Mexico.
