In 1981, Stephen Porter, Len Whitlock and Erik Kramer set the lowest diving record at 2250 ft. and lived in an eight ft. diameter chamber for 43 days breathing in a mixture of: oxygen, helium, and nitrogen. Another one of Cousteau’s inventions was a diving saucer, similar to a modern day submersible vehicle, it propelled water out of jets to move and steer it in any direction underwater. He also made an extraordinary movie called “The Silent World”. In the United States, his spectacular movie won an Academy Award, and in France his movie won the Grand Prize at the Cannes Film Festival.

While you are diving, you cannot speak verbally to your instructor or buddy as you are diving, so you must use Scuba Diving sign language. You use a bonanza of hand signals to communicate with your fellow diver on your situation, how much air you have, where to go, and many other indications. These signals are vital to your safety because you could be low on air, you could see a shark, or you might have to go to the surface with your instructor.
