Abstract

PURPOSE:To enable observing the underwater from the upper surface of the float by integrating the upper surface and the lower surface of a float. CONSTITUTION:A float is formed as a hollow body, whose upper surface is made into a transparent plastic face 1, and its lower surface is made into a transparent plastic face 3 likewise, so that the underwater can be seen through the upper transparent face 1 of the float. In consequence, observation under water can be done from the float without dipping a man's face. In addition, the shape of the float can be made into a boat-shape, a floating-ring-shape, a raft-shape or other optional shapes.
