Technical
Courses
address
particularized
areas of
technical
diving.
Accordingly,
technical
courses
are
designed
to
provide
more
detailed
training
than
specialty
diver
courses
and
result
in more
extensive
qualifications.
In these
instances,
the
qualifications
are
described
in the
respective
technical
course
standard.
They
provide
divers
the
opportunity
to enjoy
organized
diving,
which
yields
experience
and
documents
training
in
technical
diving
activities.
Instructors
with
expertise
in
specific
areas of
technical
diving
may
design
their
own
technical
training
courses
also.
