Scuba Diving - 4th Edition

A very comprehensive theoretical manual that discusses the ocean environment, how the human body reacts and adapts to that environment, and everything a diver needs for a successful diving experience. The author spends a lot of time on equipment and discusses every part in detail: what it is, how it is used, how it is maintained and cared for, what to consider when buying it, how different products compare, etc. He also explains different diving techniques, pressure problems and solutions, entering and exiting water with full diving gear, hand signals, and emergency skills. It is the perfect companion to a scuba diving class.

This book was extremely helpful when I started to learn scuba diving. I was not required to have a text for my basic scuba diving course and this is a book I purchased to give myself more information. Now that I'm working on getting certified to be a teaching assistant (NAUI) for basic scuba diving, this book helps me maintain the knowledge that I learned in the basic course. I do recommend this book for any one and everyone interested in diving as a career, sport, or hobby.

I used this book when I first learned scuba diving. I didn't have a book to use and this book helped a lot. It goes into a lot of technical information and environmental factors which aresomething every diver needs to start learning. It is easy for beginners to understand. This book is something that has interested me in continuing with diving and has helped me on dives.

I took a 7 week open water certification class, and this was the required text. I read the entire book front to back in one sitting because it was very interesting and contained all of the information needed to pass the written examination.Graver especially makes a great effort at explaining difficult information so that anyone can understand. Learning dive tables, how to plan dives, gas laws, physiology, physics, rescue techniques, and how to treat injuries was painless using this book. The text is also loaded with clear, colorful pictures to help explain some of the things he talks about such as how to don equipment, how the moon and sun effect tide, swimming techniques, what equipment looks like, and how waves and other concepts such as thermocline affect your dive.This is a wonderful book for anyone beginning to dive, and it's a great resource for anyone who is ready to refresh after a long absence from diving.

I bought this book to prepare for the PADI open water certification. I found it to be a very well organized book that did an excellent job of explaining everything from the concepts of boyancy, diving physiology, to the dive tables. It will serve as a great resource the next time I plan to dive. The opening chapter discusses the the sensitivities of the underwater world and the importance of respecting this environment. I really appreciated this chapter after my first dive where I witnessed a group of reckless divers whom were basically out of control in the coral reef. I highly recommend this book to any beginning diver that wants to prepare for open water diver certification.
