Fifth Edition

Recreational scuba diving has progressed from its beginnings in the 1950s. Dennis Gravers fifth edition of Scuba Diving is uniquely designed toward a level of education that provides new divers with an exceptional level of knowledge while promoting safety and enjoyment. With our training agencies, Scuba Educators International (the former YMCA scuba program) and PDIC International, our goal is to provide a full education for new divers. This text accomplishes that goal and perhaps can also be used for advanced programs as well.

At a time when instant gratification leads many to seek recreational activities that can be accomplished with little effort in a brief time, scuba takes new divers into an environment that remains challenging. Therefore, the need for a full education has not changed. Perhaps the delivery of information will change in the future; however, the need to understand the complexities of the undersea world will not.

In addition to bringing this fifth edition up to current levels of information, Dennis has provided end-of-chapter questions that result in additional learning. This edition is among the best of texts in the scuba industry for new divers.

Dave Barry wrote, There is nothing wrong with looking at the surface of the ocean itself, except that when you finally see what goes on underwater, you realize that youve been missing the whole point. I couldnt agree more.

My appreciation includes the review of the Application of Knowledge (AOK) questions by Dr. Terry Beattie, former diving medical services officer for the Washington, DC diving unit. His physiology expertise was also helpful.
