It does say on the cover that it is the survival guide - it really is. I read quite a few rescue diver manuals, but this completes it. From the planning to the equipment to the environment to the first aid, everything is technically covered. There are some sections that provide some tips on diving skills, and dive professionals should pay attentions to them as those little things can save a lot of your time and your students' in the class while you actually are passing important dive safety tips down to them.
Some sections, especially rescue technique sections, were visually explained so that a reader can visualize the body positions also.
Orr's Safety Stop section was added touch to the book as it is based on the real story and experience. Some of them made me think of what I would do if I were in his position so that a rescue would be conducted safely.
As certified dive equipment repair technician, I seriously appreciated Equipment section of the book. It is easy to forget that we carry life-support equipment while having fun underwater, and this book not only took it seriously but pointed out the basic facts that are easily forgotten by divers in professional manner.
Overall, I'd recommend this book to all divers as this is easy to read comparing to other dive safety books out there that make my head scratch, but I'd highly recommend to all rescue-level divers that want to extend their knowledge in overall dive safety, and instructors should definitely use this book as a reference and addition to your dive safety related courses and encourage your students to obtain a copy. They say that the knowledge is a power, but it really is.
