Title: What is the point of this book?
Review: Seriously...who in their right mind would spend money and buy this book? You should be certified by a major agency like PADI or NAUI before diving i.e. you get their manuals as part of their training which tells you most of the things you need to know. The rest comes from practise and more advanced training. I think the Dummies series needs to stop wasting paper by printing these useless books and focus on topics where they are actually needed.
