Kirby Morgan 77
The diver must be tended at the surface at all times by a trained, qualified commercial diving tender. Never dive without a qualified tender holding your diving hose.
The diving control station can be at the surface, in a diving bell, or in a submerged habitat. The diving control station is the center of the air/gas supply, com- munications with the diver, and diving procedures. The station can be as simple as a tender with a set of “phones” (communication amplifier), or as complex as a control van in the midst of a saturation system.
WARNING
All diving always involves the risk of decompression sickness. Omitted de- compression due to loss of gas supply or other accidents can cause serious injury or death. The use of the Kirby Morgan helmets or masks cannot prevent this type of injury.
KMDSI manufactures a complete Air Control System, the KMACS 5™ with integrated communications and pneumofathometer. This portable system can be operated on either a high pressure air supply or on a low pressure compressor. The Air Control System has a specially designed high pressure regulator that re- duces high pressure air and provides an adequate flow to support divers to a depth of 130 fsw (40 msw)
The helmet demand regulator and side block assem- blies have been designed to operate with a supply pressure from 130 p.s.i.g. (8.8 bar) to 225 p.s.i.g. (16 bar) over ambient pressure. This wide operating range allows flexibility when using various gas sup- ply systems.
WARNING
High pressure supply regulators and as- sociated piping systems for surface sup- plied diving with Kirby Morgan helmets and masks must be capable of delivering a minimum of 3.2 acfm to the diver at depth. Only systems that can deliver the required gas flow should be used.
For maximum breathing performance it is desirable to maintain an over bottom supply pressure in ac- cordance with the

Early production of the REX 77 helmet had a much different surface finish than what is found on current production runs.
Earlier helmets shells and components were finished using a combination of glass and Stainless Steel beads; this gave a dull or flat looking surface finish. Later shipments have a surface finish with a much smoother and almost shiny appearance. Although the parts are not shiny, the surface finish is very smooth. A
