Designed for newcomers to Twinsets this has proven to be an exceptionally popular course which covers a considerable amount of skill development.
The course was originally intented as a workshop for both the Advanced Nitrox and Advanced Recreational Trimix courses to provide students coming on these courses with a grounding in such things as propulsion, Out of Gas drills and Valve Shutdowns. Many previous students had struggled with the concept of the valve shutdowns and this course was designed to give a training ground so that time on courses was not spent developing basic skills.
Any course strives to train students in new skills but the valve shutdown is recognised as causing the most problems and its an area where an additional day spent training can produce real benefits. For courses such as deep diver where students have never dived using a twinset before then it is an essential component of further training.
Twinset fundamentals takes the basic skills a single cylinder diver may already have and incoporates the use of twinsets into that skillset. Whislt most divers have a grasp of buoyancy control, the fundamentals course seeks to further improve the level of buoyancy control before then developing additional new skills such as Long hose donation, shudowns, mid-water mask removal and replacement and other practical skills.
The day consists of a briefing lecture about the history and mechanics of twinsets and their components followed by a session on equipment configuration, the various types of wing and harness available, sizes of twinset etc. We then have a dry land skill session involving the procedures for gas donation and valves shutdowns.
For the practical session 2 training dives are carried out with a minimum in water time of 120minutes- these dives incorporate various skills and techniques - more details can be found at
