Abstract: A weight system for divers employs both an interior and an exterior weight pocket. The interior weight pocket is secured at the interior distal end of the exterior weight pocket. The attachment point is a post at the interior end of the weight pocket. The weight pouch hangs from this post and is secured in the exterior weight pocket. The release force is more precisely controlled with a coil spring. More control of the opening force translates to reliability of operation and safety of the weight releasing mechanism. The weight pouch is also more precisely guided into and out of the exterior weight pocket and the lock mechanism is self-centering, allowing easy assembly or disassembly of the weight pouch into and out of the exterior weight pocket.

Abstract: Positive locking device for components of snorkels and other equipment such as diving regulators, buoyancy compensator hoses and the like. The locking device in a preferred embodiment comprises a hard plastic C-shaped ring or clamp which is preferably mechanically and/or chemically bonded into a soft plastic component connector during molding of that component. The ring or clamp provides an effective locking feature which prevents inadvertent demating of components during a dive or other activity that could otherwise result in a dangerous loss of function. An additional embodiment of the invention provides an optional indexing feature which serves the useful function of audible and tactile feedback during adjustment of components having the locking device.

Abstract: A conjoined tube within a tube located inside a lower section of a snorkel designed to steer water droplets away from the snorkel diver's breathing path. The lower section of the snorkel has two valves. One is the scupper valve positioned at the lowest point of the inside tube. The scupper valve is a light duty valve or a low resistance one-way watertight passage intended to allow droplets of water to drain into the main reservoir. The outer tube lower section contains a reservoir for holding residual water that travels down to the bottom of the snorkel and is contained therein. During the normal clearing operation, the reservoir can be emptied and water will exit out of the lower section and into the surrounding water.
