Title: What a useless book!!!!
Review: I found this book to be totally useless. I just tells you how to go to a dive shop and get certified. There is almost no useful instruction in the whole book. Just go get certified and you can skip the book. I expected info on using the dive tables or other specific info, however, I found it completely lacking anything you don't get in a basic open water class. I guess if you want to be told the kind of things you will learn in a dive class go ahead. This book does not compare with the other books in the "Dummies" Series. Don't waste your money.
