ABSTRACT:
An aquatic "dive-plane" which operates in tow behind a motorcraft. Used in conjunction with basic snorkle gear it permits the user, by the flexing up or down of peripheral wings to submerge and explore under the surface as well as to turn, maneuver and resurface intermittently for air. It comprises a body of buoyant material to float the unit for easy recovery; a pair of semi-parabolic structures of a rigid, durable transparent material which serve hydrodynamically to minimize drag and to protect the face and mask from turbulence while allowing the user a maximum view of surroundings both above and below the surface; a pair of peripheral wings manually controlled by affixed handles by which the user controls his position in the water; a pair of arm-supports by which the user stabilizes his position in relation to the dive-plane and by which an even distribution or shifting of the pulling tension is permitted.
