From eBay sale - History and development of diving and of the exploits of some of the great divers of today - men who found prehistoric human skeletons in underwater caves; others who located a sunken ship that went down thousands of years ago: a man who kills monstrous sharks with a short, hand-held weapon; a diver who found a quarter-million dollars in Spanish gold and silver: a man who rides sharks as a cowboy rides a bronc; and many others. This is a practical guide to skin and scuba diving and one that offers hours of absorbing reading for the armchair adventurer as well as the active underwater enthusiast. Along the way there is essential information for the novice and tips for the experienced diver while the reader enjoys such varied underwater pictures, exploring subterranean rivers, finding sunken treasure and recovering archaeological relics. Illustrated with drawings by Chuck Sharman and sixteen full pages of photographs by the author.
