Brylske, Alex Encyclopedia of Recreational Diving: An Encyclopaedia

While the Encyclopedia of Recreational Diving is a very informative book, it is not the 'heavy' reading that one might expect from a PADI manual. The terminoligy and concepts covered in this book nicely suppliment what one learns throughout the recreational diving classes -- novice open water dives, advanced techniques, underwater navigation, and rescue techniques. I recommend this for divers who have gone through open water and advanced classes (and even Rescue), feeling that they did not get all they could out of the classes and textbook. This book is a must for those wishing to seek a professional dive rating (divemaster and higher), or pursue technical dive certifications.
