Rich Air

Funny little specialty. No dives necessary, just theory, about 6 hours. The Enriched Air Diving coursebook has only 100 pages, most of which are pictures (as usual). So today we've learned about Equivalent Air Depth, CNS, POT and some other things. Got some new tables, though they are almost the same as standard RDP. Next class is going to be more fun as we are going to use oxygen analyzers and, of course, write the exam.
