6-9.4.1
Master Diver Responsibilities. The Master Diver is the most qualified person to
supervise air and mixed-gas dives (using scuba and surface-supplied diving equip-
ment) and recompression treatments (Figure 6-17). He is directly responsible to
the Commanding Officer, via the Diving Officer, for the safe conduct of all phases
of diving operations. The Master Diver manages preventive and corrective mainte-
nance on diving equipment, support systems, salvage machinery, handling sys-
tems, and submarine rescue equipment. Training and requalification of divers
attached to the command is conducted by the Master Diver, who also ensures that
divers are trained in emergency procedures. The Master Diver recommends to the
Commanding Officer, via the Diving Officer, which enlisted divers are qualified
to serve as Diving Supervisors. The Master Diver oversees the efforts of the Div-
ing Supervisor and provides advice and technical expertise. If circumstances war-
rant, the Master Diver shall relieve the Diving Supervisor and assume control of
the dive station. In the absence of a Diving Officer, the Master Diver can assume
the duties and responsibilities of the Diving Officer.

Diver evaluation course (CIN A-433-

tions pertaining to diving, and shall

tained and submitted as required.
