In 1973, Cressi Sub catalogue showed a "strange" regulator for the look of its first stage, unique for its hexagonal shape, never seen among Cressi gear. It is named Polaris 5; it is with balanced piston; it does not have a revolving turret, and it has its main low-pressure output first of all. In one of the 6 body sides are present other two middle pressure outputs, in the next side one high-pressure output, all characterized by a remarkable protrusion. In fact, connections are formed by a fixed hexagonal entry closed by a cap which is also hexagonal. In the middle of each side, stands out a water inlet hole for the hydrostatic equalization. The Int connection to the bottle is positioned at the opposite of the high-pressure output.

Second stage is the Polaris standard one.
There is no track of this regulator in the following years. Probably, production was stopped because of low sales success, caused by a not too pleasant look.
In effect, it is difficult to find it also in the used gear market. The item in this picture comes from Alfonso Gangemi collection.
