Abstract
An apparatus for use in a fluid medium which activates at a deeper depth and then releases at a lesser depth. A rod depresses a spring in a housing. The rod is prevented from being ejected from the housing by a ball bearing which engages between openings in the rod and the housing. When in use, the pressure exerted by the fluid medium forces the rod deeper into the housing. When the first depth is reached the ball bearing disengages from the rod and the device is activated. As the activated apparatus rises, the pressure on the rod decreases and the rod moves out of the housing. When the deployment depth is attained the housing floods and the rod is ejected.
