US Navy Diving Manual: Revision 4

The 1999 Version USN Diving Manual discusses topics with the same thoroughness as the NOAA Diving Manual, when both cover the same topic. However, elements related to Navy or military diving, surface supplied air, and hardhat diving are of academic value to most SCUBA divers. Often looked for and thus should be mentioned, both Manuals cover thoroughly diving medicine: USN chamber decompression, dangerous marine animals, and emergent care procedures. However, NOAA's emphasis on SCUBA and many items with some relevance to sport divers, such as survey methods or search and recovery techniques, put it ahead of the USN Manual, on a relevance per dollar basis. One item of note, the USN Manual seems to have omitted the long term 02 exposure tables ... this maybe problematic as nitrox increases in popularity.
