Deep Into Deco, Revised Edition has been fully updated to reflect the latest research outcomes. 

  • Chapter summaries have been added to give a quick overview of each chapter.
  • A new section on nitrogen and helium kinetics has been added.
  • Av second appendix was added for calculating the acceleration in post-diving no-fly time associated with breathing surface oxygen. 

What makes this book truly stunning is that it is not only straightforward, easy-to-read and understand and free from technical jargon, but it also portrays the latest developments and controversial issues in technical diving.

From the early history of experimental trial and error to the latest innovations and changes in the decompression arena, Deep Into Deco, Revised Edition brings the science into sharp focus. Throughout the book are demonstrations of how deco schedules are calculated in commercial software packages, without elaborating on mathematical equations or source code. Also, a grab-bag of additional points of interest that contribute to our current understanding of decompression theory is explored in detail.

This book is a must read for any diver looking at understanding decompression theory, how it evolved, what it accomplished and where the latest research is heading.

- Dan Orr, President Emeritus of Divers Alert Network (DAN)

Quotes wDeep Into Deco is a stimulating read which covers almost every facet of diving from breathing to technical decompression. It is well referenced and dives into (forgive the pun) great detail concerning the past and present of diving theories. I recommend this book for all divers from novice to technical expert because Asser Salama makes even the most difficult topics seem easy and understandable. No diving collection is complete without this super overview book. I will keep mine on the coffee table as a discussion piece.” —Commander Joseph Dituri, US Navy Saturation Diving Officer (ret) and Vice President of IANTD

Quotes w“This book is long overdue. And it’s worth the wait. What Asser Salama has accomplished with this book is remarkable. He has taken that early history of experimental trial and error and produced a stunning reference text that brings the science into sharp focus.” —Bret Gilliam, founder of TDI
