The history of diving helmet designs from around the world. The diving helmet is an iconic piece of history. Years after it has been retired by modern navies and professional divers it retains its place on qualification badges and dive club logos. The early years of diving produced some amazing and some bizarre ideas and this book tracks their development and the reasoning behind them. The different approaches taken by the designers and their relative merits and successes are covered, taking away some of the mystery from these copper, brass and bronze legacies of a bygone age. With over 60 photos and illustrations the author also examines the various dangers of diving including the obligatory giant squid, as well as chronicling homemade diving equipment and his own 'deep sea diving' adventure. With a foreword by Tony Groom, author of Diver and In2Deep.
