80 NAUI Nitrox Diver
Figure 7-7 With your properly filled nitrox cylinder
and knowledge of its contents, you are
then ready to check eachother's dive gear
and begin your dive.
And so, at last, you have it all together, and you are
ready to enjoy the world of nitrox diving. Armed with
your cylinder of enriched air nitrox – perhaps blended
to your personal specifications, your knowledge of the
risks, limits, and advantages of the gas that you are about
to use, an appropriate dive plan, and a compatible dive
partner, you head off to the dive site. There you and your
partner assemble and don your equipment, rehearse and
review your dive plan (including a review of your MOD),
mutually check each other’s gear, and begin your dive.
