Abstract: The present invention relates to a scuba diving fin. The scuba diving fin utilizes adjustment mechanisms for the fin blade to be rotatably adjusted and locked in a first position that is in the same plane as the diver's leg and, alternatively, adjusted and locked in a second position behind the diver's calf. The present invention also utilizes a ski boot-type rigid outer shell, including the ski-boot style of clamping device used to close the boot around the diver's lower calf and ankle area. The present invention further utilizes a diver's neoprene bootie attached to the rigid outer shell to provide for a flexible lower boot portion. The fin blade first position is for diving and the second position is for walking or climbing steps.

Abstract: The present invention relates to a suspension system for a toy vehicle. The suspension system is independent in that it comprises at least four damping mechanisms (shock absorber), each shock absorber being located proximal to each wheel location. Each shock absorber utilizes a tensioning device, such as a compressed spring, positioned between the toy vehicle chassis and a suspension arm, to provide the active damping feature of the invention. Each shock absorber also utilizes an adjustment means, such as a screw, to selectively change the distance between the suspension arm and chassis. As the screw is adjusted, so the spring is either more or less compressed, providing for a stiffer (more compressed) or a softer (less compressed) suspension.

Abstract: A scuba tank caddy, having an optional gear drying rack and an optional portable shower, for improving the comfort and convenience of the scuba diver. Additional advantages include, but are not limited to, retractable wheels, telescoping shower head, tank-pressurizing freshwater shower, and corrosion-resistence.
