Course description:
This course provides the skills for Deep Air Diving with the use of more than one Rich Nitrox Mix
(up to 100%) as decompression gas. The course covers further
equipment configuration for deep diving (more stages differing
sizes), trapeze use, and the use of advanced decompression equipment
(obligatory emergency extra deco gas for team). Plus new training
skills when working with different 'Team' sizes to challenge
your personal stress limits, Narcosis Management, improve and
build experience required to competently utilize air for dives
up to 55msw that require staged decompression, utilizing nitrox
mixtures and oxygen during decompression.
An invaluable stepping stone course which introduces alot of
skills commonly used on trimix dives particually for the UK diver.
ERD progresses your skills to work towards the ultimate goal
of Trimix. You will be gaining the required technical experience
for this level and then be more ready for the next Trimix level
step. The ERD course is also a min requirement for such areas
as Bikini that offer 55m dives and do not have helium for Trimix
divers.
