Fully updated and revised. Award winning Deco for Divers provides a comprehensive overview of the principles underlying decompression theory. Mark Powell has written a book that for the first time allows the average diver to fully understand the principles behind this fascinating aspect of diving. This book bridges the gap between introductory books and source scientific information. What I wanted was an intermediate overview that went into more detail but wasn't written for academics or researchers. When I became a technical diving instructor I started teaching other people about decompression theory. I tried to give an overview of decompression theory at this intermediate level to give my students a better understanding of what was happening during decompression dives. This was always very popular amongst divers who, like me, had always wanted to understand more about the concepts and models underlying decompression theory. I was always being asked if I could recommend a good book which covered this area but as before, there was no such text available. Over time I started giving out notes for the decompression theory portion of my courses and these notes started building.Initially they were just a few pages but the notes became more and more comprehensive and started to cover more and more areas. Eventually they grew into this book. Eurotek 2010 - Winner Publication of Significance Award. TekDive 2014 - Winner Media Award.
