Porpoise scuba

The “Porpoise” book reprint

Australian Diving Technology the World Copied

By Des Walters, Des Williams, Mel Brown AM and Tony Gregory

When La Spirotechnique and Aqua-Lung were only producing twin hose scuba and had never dreamed of a single hose system, along came an Australian who changed scuba diving forever. This is the complete story of the engineering brilliance of Australia’s Ted Eldred and the development of his Porpoise scuba, which set today’s world-wide diving standard. Acknowledged by many including HDS US and HDS Australia-Pacific, as the first to mass produce the single hose, 2 stage scuba system as used by scuba divers today.

In this book you will learn about:

• the history,
• prototypes
• early production,
• timeline of model changes,
• parts lists,
• exploded parts views,
• marketing,
• the 1961 Lake Eucumbene dive,
• the 1956 Elcho Island pearl divers school and
• the first Australian recreational scuba school.
A prolific inventor of diving equipment, Ted Eldred’s inventions also included an oxygen rebreather and hookah unit. Eldred’s manufacturing company was named “The Breathing Appliance Company” and his equipment was branded with the “Porpoise” name and image.

Researched and written over three years by HDS Aus-Pac members Des Walters, Des Williams, Mel Brown AM and Tony Gregory; as a salute to Ted Eldred’s pioneering contribution to the world of recreational scuba diving.
