Abstract
A tow sub that has a bullet-shaped shell to cover the front of a diver. The shell is large enough to be comfortable for a diver lying in the shell. The shell has lenses that provide ample vision for the diver. The tow sub has two independent control surfaces. The first, is a fixed dive plane that can be attached to the top, sides or bottom of the shell. This dive plane acts as a diving plane. The second is a pivoting rear elevator control surface that is mounted on a tail boom. The pivoting elevator is controlled from within the shell by a yoke controller. The tow sub has a tow hook that has a quick release mechanism. Using this mechanism, the diver can disconnect the sub from the tow line from within the shell. When disconnected in this way, the sub stops and slowly rises to the surface.
