ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a diving apparatus for a user that cannot operate a conventional diving apparatus, including animals. The invention has been employed with an animal, the wellknown diving dog, Shadow. Shadow, being a canine, cannot communicate with her owner and handler, Dwane Folsom, and is unable to operate a scuba apparatus herself.
Accordingly, the present invention provides a means for Shadow to dive both in swimming pools and the open ocean. Shadow has accomplished numerous dives in pools and in the Carribean Sea around Grand Cayman, British West Indies. She has appeared on approximately thirty television programs or news reports, many of them broadcast nation-wide, such as CBS's morning news and ABC's “Good Morning America,” and is a highly experienced diver.
SUMMARY OF THE INVENTION
According to the invention, there is provided a helmet that has an opening for the user's neck. The helmet includes a regulator mounted on, its external surface. The regulator is made from a conventional scuba demand regulator, but is specially modified. A muffler is provided to reduce or eliminate air noise. The helmet can be equipped with an intercom system, and can receive a weight to compensate for the user's buoyancy and any net moment about the user's center of buoyancy. The helmet is attached to a harness that supports the helmet and a tank of air or other breathable gas. The harness also receives compensating weights.
