Review title: Where all Scuba courses originate...
Product review: The US Navy Dive Manual is the manual from which all recreational and rescue dive programs originate. The RSTC and WRSTC uses this as a standard prior to their approval of any scuba program in the world. Should you be interested in learning the history of scuba this book is the most comprehensive every found. We should remember the "expendable" Navy divers whose lives were given to develop this manual. I am a scuba diver with over 30 years diving experience and am currently a scuba instructor of over 20 years. I keep going back to the US Navy Dive manual to refresh dive theory, physics and physiology. I have always found the answere for which I was searching here!!! Doc
