Tim Ecott's :Neutral Buoyancy, adventures in a liquid world, is an excellent book that tells the interesting story of the humble beginnings of the Self Contained Underwater Breathing Apparatus.
Tim Ecott is a journalist and dive master who shares some of his own exciting dive adventures, from diving the shark rich waters of the Caribbean to a near death experience in the cold grey waters of the English Channel.
The author has utilized many facts to weave a great story about the entire history of scuba and the early pioneers of the diving world.
Tim also adds an historic account of the early sponge divers and the challenges they faced as well as a section on Free Diving.
This book is both exciting and educational, and an excellent read for both new divers as well as the experienced.
I highly recommend reading this one! Well done Mr. Ecott!
