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.
