Thx--that sounds like a good idea. I may book three on some days, two on others, if that's possible. Since I'll be on the same small island without a car the entire time I figure I won't need as much time to do non-diving things as in a place like the Keys where there is so much to see on land.



DandyDon:
Some like to do 2 in the morning, then take the afternoon for non-diving. Some like to take the morning off to get over the night before, then do 2 in the afternoon, but the waves can get up. I go for the diving, and always try to book 3 a day - always, if I can.

I've arranged a package for March that will give me 3 a day for 3 days, breaks - including lunches at beach club, and a night dive. That's my mind of trip. A diving trip. :59:
 
Hi,

I was one of the people in the trip that Joel was talking about. The mix of divers ranged from one student finishing her open water training to several newly certified divers to at least one diver with more than 500 dives. This list does not count the two instructors that came from Arizona. Among the group there were at least 3 analyzers, by prior arrangement the instructors brought at least 2 that I saw, these were available for the entire group to use, and were considered "group" equipment. I also brought my own analyzer. As Joel said, there was no analyzer provided by the boat.

When I analyzed my own gas the sticker on the tank was usually fairly close but on one tank it was 1.8% lower than I analyzed it to be. This difference is within the 1% accuracy variable that most analyzers have. (If the first analyzer read 1% low and mine read 1% high the real mix could have been almost exactly between the two readings.)

What lesson did I learn, well it was one I already knew... Bring an analyzer. If the commercially available ones are too expensive and you are handy make your own, that is what I did. It cost about $110 including the pelican box and the upgraded long life sensor. If I had not brought mine the other 2 analyzers that were brought from Arizona would have sufficed, if we had relied on the boat to provide an analyzer we would have been forced to completely trust the stickers. Even if the boat has an analyzer, it can fail. My analyzer could have failed. The ones from Arizona could have failed. The best part was we had enough to do what we needed to do and dive safely and happily.

Most of our dives were shallow, the deepest I got was 78 feet. All of the Nitrox tanks were supposed to be 36% but I got one that was labled and analyzed near 32%. Personally I like shallower dives if there is somthing to see, better light and longer bottom times. Most of the dives were in the 40 to 50 foot range.

It's standard operating procedure for our people to bring analyzers on trips. Even if we know the operator will have an analyzer. It's how we do things.

While it's possible for units to fail, and they do from time to time. Whenever we run a trip or go off to a location where we will not have the opportunity to get special tools. We run a pre-check on our units, we change the batteries, and we change out at least one sensor to a brand new one. We then run that sensor for 2 days on a few dozen samples to make sure its working correctly. It's just how we do things.

Mark, we are glad you had a good time. I hope to see you with me in La Paz in January

Joel,

I had a great time, but I am afraid I will be in Cleveland shivering in the snow while you are basking in the sun.

By the way, compliments to Kathy, and Scott. A very nice trip!

There are at least two shops that I know of on the island that fill their own tanks and one of them does Eanx. There could be more, I´ve only had a small taste.

Sand Dollar has a compressor and Dive Cozumel (Yellow Rose has a small compressor). Roli (Yellow Rose) mostly caters to tech divers and can also do tri-mix fills. However, if you are notdiving with him, he won't fill tanks for you due to his limited capacity. You'll also pay a HIGH premium to get nitrox from him. Scuba Club may fill their own tanks as well...not sure. Those are the only operations I know of that fill their own tanks.

There is a new/old (existing fill station/new owners) fill station that is partnered with a dive shop, but they are a central station also filling tanks for other shops.
