Cave Diving Communications

NOTE: This book looks a bit ratty from being well read !
I bought this book several years ago when I was first starting to consider
technical diving. On the advice from a well known cave diver that I respect.
He mentioned to me the importance of underwater communications, and how
they would affect my diving in the future.
The book is full of useful information, and a few good cartoons. Here
is a small quote from the acknowledgments section, and it explains a
lot of the reasons and method behind this publication.
"This book does not pretend to be a trailblazing epic of heretofore
unheard-of methods of underwater communication. It is rather a compilation,
summery, and discussion of the techniques and knowledge that have been
developed over more than three decades of cave diving in this country."
I read this book and adopted most of the signals that are used and have
found them to be more than helpful in several situations (dive buddies
have read it to). This will greatly enhance your communication abilities
in the under-water world. We have "invented" several new hand signals
that are used in our every day diving, but this is the foundation that
we have built our communication on.
