21. MASTER JACKET
(certified as CBRD-EN 12628, that includes also the EN 1809 norms, that means it can
be used as buoyancy compensator underwater as well as Life Jacket on the boat)
The original design of this legendary model was developed in 1978: it was the first diving
Jacket ever produced and its design and technology is so successful that as of today, it is
practically unchanged from the original.
The Master Jacket is quite different from all other models on the market due to its “three
dimensional balance” buoyancy control, regardless of the sequence of movements or
in what position the movement begins underwater, the internal air bubble cannot cause
rotational movements,which would destabilize the diver (fig. A).
This outcome is owed to the peculiar internal bag design, that uses three interconnecting circles
or passageways, permitting the air bubble an unobstructed circulation (fig. A1). If the ring is
interrupted (fig. B), a rotation of the ring itself, which would bring one of the ends (E or E1) to the
highest point (where the bubble (O) resides), would cause the rotation to stop. If the ring is not
interrupted, however, the rotation can continue until it reaches the most stable configuration. This
guarantees not only an unparalleled level of comfort during diving, but also a “face-up” position
of the diver on the surface, even in case of unconsciousness, providing thus an inherent level
of safety. For this main reason, the Master Jacket has been tested and certified as the unique
worldwide CBRD (Combined Buoyancy Rescue Device): meaning that the Jacket can be used
as a buoyancy compensator underwater as well as a Life Jacket on the boat!
Other skilful technical solutions and quality materials support the basic safety concept:
the Master Jacket consists of two bags: an internal bag that holds the air bubble, made
of polyurethane/polyether, radio frequency welded, and an external bag made of tough
polyester fabric, sewn with thick polyester thread, that guarantees mechanical and abrasion
resistance.
