Abstract
The diving device is comprised of a hollow hull with a side profile which is rounded at the front and tapered at the back for low resistance in water. The hull includes side wings on opposite sides of a bulbous body. Handles are arranged in the wings. The buoyancy of the diving device is adjusted by letting in or draining water through a valve at the back of the hull. Fill level marks on the hull show how much water is inside the hull, which is preferably transparent to show the fill level. The buoyancy provides resistance during descend and assistance during ascend. A sealed, air-filled shell is positioned inside hull to provide a minimum amount of buoyancy even if the hull is completely filled. A valve at the front of the hull may be opened during ascend to release bubbles for amusement.
