The U.S. Navy Diving Manual is a book used by the US Navy for diver training and diving operations.

Overview

The US Navy first provided a diving manual for training and operational guidance in 1905, and the first book titled Diving Manual was published in 1916. Since then books titled Diving Manual or U.S. Navy Diving Manual have been published several times, each one updating the content of the previous version. The amount of information provided has tended to increase over the years, Revision 4 has about 950 pages, and the manuals are illustrated with contemporary photographs, diagrams and graphs.

Content

Content has varied in the various editions, and the order and layout have changed over the years. It remains one of the most comprehensive textbooks on the theory and practice of diving generally available.

Impact

Before the establishment of recreational diver certification, the U.S, Navy Diving Manual was used as the training manual for recreational divers in the US, and was frequently referenced in other English speaking countries. It was also used as training material for commercial divers, and has been the standard text for the U.S.Navy for diver training.

US Navy decompression tables and variations on the originals have been used worldwide by recreational and professional divers. This trend has decreased somewhat with the availability of economical and acceptably reliable decompression computers. One issue for recreational use was that the Navy decompression tables were considered relatively high risk for decompression sickness when followed to the limit. For divers without convenient recourse to a decompression chamber, this was considered an unacceptable risk, and various modifications to the tables were made for greater conservatism and convenience of use. Even after the recreational diving industry published a variety of training manuals, the U.S.Navy Diving manual remains a respected and widely used reference by recreational technical and professional divers worldwide. This may be partly due to the ease of access, as the later versions have been freely available for download as pdf files.
