hand laid fiberglass. The head harness is a molded,
strong tear resistant neoprene rubber.
The hood, which attaches to the mask frame with
welded stainless steel bands, provides warmth for
the divers head as well as pockets for the earphones.
The communications connections can be either a male
waterproof plug in type or bare wire posts. Both this
mask and the KMB 28B feature the new Tri-Valve™
Exhaust System.
The KMB 28B BandMask
similar to the KMB 18, with many parts on the KMB
18B being interchangeable with the KMB 28B. The
major difference between the 18 and 28 is the material
of the mask frame itself. The KMB 18 has a fiber-
glass frame (yellow) while the KMB 28B frame is an
extremely durable injection molded plastic (black).
Other differences include:
1) The main exhaust body of the KMB 28 is part of
the frame itself and uses a #545-041 main exhaust
cover
2) no comfort insert is required on the 28

The EXO Full Face Mask is designed for both
surface supplied and scuba diving. By enclosing the
divers eyes, nose and mouth, the EXO permits nearly
normal speech when used in conjunction with most
wireless, and all hard wire underwater communica-
tion systems.
The EXO BR (BALANCED REGULATOR)
shown here is designed to meet or exceed recom-
mended performance goals in both scuba and surface
supplied modes and is
passes European standards for regulator performance.
™
The Balanced Regulator helps reduce the work of
breathing for the diver by balancing the intermediate
air pressure against the valve sealing pressure inside
the regulator. This enables the regulator to instantly
adjust to changes in line pressure. The balanced
regulator is adjustable for a wide range of intermedi-
ate pressures between 90 PSIG – 250 over ambient
pressure (6.2 – 17 bar).
Both models have a modular communications de-
sign that permits rapid and simple maintenance. The
optional Hard Shell provides surfaces for mounting
lights, cameras etc.
