I dove about 30 dives over 3 weeks in Bonaire, and I found that I was getting pretty tired by the end of the day. Asleep by 9p kind of tired. I'd take a day off diving, and I'd be just fine again. I always dove well within my NDL, and never had any worrysome pain. Just sleepy.
So, I'm about to do another week of 2-4 dive days, and I currently taking the online PADI Nitrox course. I'm not a big fan of the online training, but, there it is.
I know from reading the board and the course material that I am responsible for making sure the mix shown on the tank is actually in the tank, and I'm pretty clear on why, (1.6 and NDL).
Yet, when I was down in Bonaire, I see the dive shop stack Nitrox tanks outside, with a piece of masking tape on them indicating the mix. The mixes shown varied from 30 to 33%, which told me the tank was probably filled by the partial pressure technique, but that is just a guess.
So, I see people just picking up these tanks, not testing anything, and just driving off. Okay, maybe they tested them later, just before the dive... (I doubt it.):shocked2:
Here is the thing. Do I need to buy a $200+ Gas Analyzer to have in my dive bag, and test all the tanks I pickup, or on the dive boat? Does a shop that does Nitrox fills, offer a analyzer for the public to use?
I'd like to know, who out there owns their own? If you don't own your own, what do you do?
Thanks everyone,
Mortis.
