Role of the Advanced Diver - Theory Lesson AT1
|
|
Lesson Objectives
|
- The Advanced Diver Course covers diving and marshalling in more
challenging conditions and for unknown locations. Extending a
diver's own experience supports not only being able to lead other
divers who are similarly progressing their experience, but it
also broadens the role that they will play in a branch.
This lesson looks at the role of the Advanced Diver as a senior
diver and dive marshal. It introduces them to the identification
of unknown sites from charts and from other information, the planning
needed to dive these sites and an introduction to weather to help
anticipate conditions for diving them.
|
Achievement Targets
At the end of this lesson students will:
|
- Understand that the role of the Advanced Diver includes developing
their own diving, planning and marshalling skills
- Understand that doing so will not only support their status
as a role model for all other divers and dive marshals in the
branch but to those outside the branch too.
- Understand that risk assessment is inherent in dive planning
- Understand that the site may put constraints on the level of
diver able to participate in the dive, as well as other constraints
on the numbers of divers able to dive the site, e.g. boat space
or availability
- Understand how to assess an unknown site's conditions from use
of charts, tide tables and other information.
- Understand how to determine the depth and tidal flow on a site
at a given time
- Understand the basic principles of weather patterns to be able
to anticipate conditions for planned dives from weather forecast
information
|
|
The following items will be needed:
|
- Charts and Chart 5011. Copy of tide tables relevant to the charts
being used

Advanced Diving - Theory Lesson AT2
|
|
Lesson Objectives
|
- Advanced Divers will be continuing to extend their diving experience
and this lesson emphasises the importance of planning, anticipation
and preparation both from the diver's perspective and of equipment
considerations. Additional equipment to support advanced dives,
decompression and searches is also covered. Advanced Divers may
be diving with divers using other equipment for which they have
received additional training such as Nitrox, rebreathers, Trimix
and full face masks. Some Advanced Divers may already have completed
such additional training but the lesson covers the various areas
for general awareness and introduces the variety of choice of
equipment and diving gas available to recreational divers. Whatever
route an Advanced Diver chooses to follow, the core diving skills
remain the same, all training within the BSAC is designed to offer
its members a platform from which future choices can be made if
they so wish.
|
Achievement Targets
At the end of this lesson students should:
|
- Understand that extending experience, whether by deeper or more
challenging diving, requires planning, anticipation, awareness
and responsibility
- Understand that extending experience as Advanced Divers requires
personal assessment to ensure that the diver is prepared and ready
to undertake a dive
- Understand that to extend experience in deeper or more challenging
conditions requires personal equipment that ensures adequate gas
supply and independent back up systems
- Understand that equipment configurations are personal to the
diver and their dive needs, but familiarity with all their equipment
is an absolute 'must'
- Understand that additional support equipment may be needed for
deeper or more challenging dives to facilitate decompression obligations
- Understand the basis of surface and underwater searches
- Understand the different gas mixes and equipment available to
recreational divers
- Understand that as Advanced Divers, their development and enjoyment
of the sport doesn't stop with this qualification. Many of the
skills learned during the course and subsequently put into practice
will undoubtedly put them well on the road to progressing to the
highest diver grade - First Class Diver

Organising Diving from Different Platforms -
Theory Lesson AT3
|
|
Lesson Objectives
|
- Advanced Divers are going to be marshalling a wide variety of
diving and this will involve different 'diving platforms'; small
boats that belong to the branch, day charter boats and live aboard
charter boats - generally booked for branch expeditions or diving
holidays. The Advanced Diver will, in many cases, be the senior
diver and it is their responsibility that diving and associated
activities are run as safely as possible. In some cases they may
be the sole Dive Marshal; in others there will be additional Dive
Marshals and assistant Dive Marshal support. Whether the Dive
Marshal holds boat handling qualifications or not, the marshalling
of boat dives includes important liaison with cox'ns and Skippers
and, if on holiday, dive guides or local instructors. As a senior
diver and Dive Marshal, sea awareness and being able to assist
as crew is an important aspect of the Advanced Diver's overall
role. Going to sea and learning from others, builds on the Advanced
Diver's experience base, not just for diving but also for boat
and diver management skills
|
Achievement Targets
At the end of this lesson students should:
|
- At the end of this lesson students will:
- Understand the different types of diving platform and their
associated Dive Marshalling and organisational considerations
- For small boat diving and Cox'n liaison
- For charter boat diving and Skipper or Dive Guide liaison
- Understand some basic seamanship for increased awareness when
marshalling from boats. This includes common nautical terms when
using boats, buoyage, and introduction to the Rule of the Road.
- Understand the importance of crewing to support any boat diving
and marshalling activities including some basic ropework
|
|
The following items will be needed:
|
- Charts, parallel ruler, dividers. Two pieces of rope per student
for the knot tying practical

Review of Diving Conditions and On-Site Fist
Aid - Theory Lesson AT4
|
|
Lesson Objectives
|
- This lesson is a review of diving related conditions and on-site
oxygen first aid. Also included is a reminder of rescue management
considerations including contacting the emergency services
|
Achievement Targets
At the end of this lesson students will have reviewed:
|
- General predisposing factors that can lead to diving incidents
- Gases under pressure and their effects
- Nitrogen - DCI, Nitrogen Narcosis
- Oxygen - Oxygen toxicity
- Carbon Dioxide - Carbon Dioxide toxicity
- Carbon Monoxide - Carbon Monoxide poisoning
- Near drowning
- Shock
- Missed decompression
- The importance of administering fluids when DCI is suspected
or present in a casualty
- Using Nitrox/alternative gas supplies for use when emergency
oxygen has been consumed
- Practical use of oxygen admin equipment
students should be
- competent and confident in their ability to administer oxygen
to a breathing casualty and to a non-breathing casualty with no
circulation. Overview of managing a diving incident and contacting
the emergency services
|
|
For each pair of students, the following equipment is required:
|
- A resuscitation manikin
- An oxygen administration set
-
- Where there are more pairs of students than the number of manikins/oxygen
administration sets available, the duration of the practical elements
of this lesson should be extended pro rata, so that each student
experiences the specified periods of practice. The duration of
practice is very important in not just achieving, but consolidating
the skill levels and hence should not be truncated.
