Assigned reading for my PADI SCUBA diving course. I think it's a good overview of the skills I'll need - it had lots of illustrations, self-tests and was reasonably interesting to read. After reading it (and watching the accompanying PADI video) I passed the knowledge exam with 95%. If I drown, I'll let you know in a follow-up rating....
