Twinset Skill Developement Course 2020

I am sure there quiet a few divers out there, I was one, who decided twin cylinders were for them and kitted up. Having watched others who use twins sort of got a grasp of how to dive them. Oh so little did I know.

The Mistakes I made

Like many I purchased my first setup second hand. It consisted of twin 12l cylinders. Attached to each cylinder was a slob knob, yes one on each cylinder. Plus a dual bladder with harness and Stainless Steel backplate. The whole configuration was in excess of 100lbs (45Kg).

Personnaly I weigh in around 160lb (70Kg). Trying to maintain neutral buoyancy was a problem. The 12l cylinders did not last very long and were exchanged for 10l cylinders.

After this the bladder started to bleed air, inflate and increase buoyancy. The task loading having to manage 3 buoyancy cells (Drysuit) became rediculous. That did not last much longer.

The moral to this story is that you must consider what you buy before you rush out. Had I taken this Twinset Skill Developement Course first them maybe I would have avoided some uncomfortable dives plus hairy moments.

The theory sessions were delivered over two days. Following each session a practical was organised to go through the physical elements of the course.

Elements such as an advised configuration. Shutdown drills and what to do in a gas loss scenario. There is more to this Twinset stuff than slapping it on your back.

Setting Twinset up

There was a fair amount of adjusting going on the arrive at a common standard where everyone can start from.

Considering there were a few setups begged and borrowed customising them took a while.

Twinset Skill Developement Course is a lead in to other courses.

Open Water

As ever Open Water was a delight. In 6 degree water temperature two dives were undertaken to demonstrate skills.

All attending students would like to thank Gareth Leyshon, Robin Norman and especially Paul Young for arranging the course.

Additional Benefits

Doing the SDC does give the participant more information on other aspects of twin set diving. The course covers all the recognised configurations of twin cylinder diving, independent, side mount and of course manifolded.

Myself (Robin) was introduced to twin set diving in a very similar manner whist doing a TDI Extended Range and Decompression course in Dahab, Egypt. Until that time I had never dived more than one cylinder and this introduction to twins proved to be very beneficial. It taught me the right way to dive and how to react in an emergency. This gave me the confidence to achieve more adventurous diving, and in the process all aspects of twin sets including independent and side mount.
