Twin-set Diver

BSAC’s Twin-set Diver is a great course not only to extend your gas supplies but also as a first introduction to the equipment used for safer planned decompression diving.

It’s a stand-alone course that also complements and supports the Accelerated Decompression Procedures (ADP).

I wanted to move to a twin-set as I was looking to do longer dive times, be more self-sufficient and safely plan for decompression diving. This course was the ideal introduction and I’m now confident with my kit, I am more streamlined and really enjoying my diving!

Claire Skidmore, Southport BSAC

Twin-set Diver introduces an experienced club diver to the theme of self-sufficiency within buddy diving. You will learn how to become your own first port of call in an emergency and understand the equipment needed for this.

To enrol on the Twin-set Diver course you must have already successfully completed a BSAC Sports Diver course with a 35m depth certification (or have equivalent certification from another recognised training agency including decompression and rescue capabilities).

You should also have 20 or more logged dives as a Sports Diver.

You will develop your knowledge of twin-set diving including:

Kit configuration and ancillary equipment stowage.
How to respond to kit failure.
Practical twin-set diving techniques, including gas isolation and shut-down drills.
Multi-contingent dive planning for more adventurous diving, including run-time schedules.
The Twin-set Diver course includes four theory sessions, a dry practical session and a dive-planning session. It also includes a sheltered-water lesson, and two open-water dives with planned run times of between 25 and 40 minutes (to a maximum depth of 35m or within your qualification), to ensure that you have plenty of in-water time to practise the skills and discipline needed for twin-set diving.

This is a continually assessed course during which students must reach the required performance standards.

A Twin-set Diver is competent to plan and conduct dives using a twin cylinder configuration within the limits (including depth and breathing gases) of their diver certification.

An Advanced Twin-set Diver is a Sports Diver who has successfully completed Twin-set Diver and Accelerated Decompression Procedures (ADP) courses. They can plan and conduct dives to an extended maximum depth as defined by the current maximum air or nitrox depth limit recommended by BSAC, currently 50m, using breathing gases that they are certified for.

Currently, only club members can take a course with us. If you want to get started, you can always take a trydive with us.

Your next steps – developing your skills

After completing Twin-set Diver and consolidating your skills, your options for diving will expand.

  • You can develop your decompression diving skills on an Accelerated Decompression Procedures (ADP) course. If you are a qualified Sports Diver this will enable you to extend your maximum dive depth to the maximum air or nitrox depth limit recommended by BSAC, currently 50m.
  • Progress to Sport Mixed Gas Diver (50m) after completing ADP and enjoy the benefits of reduced gas density and narcosis, which ensure greater comfort and enjoyment at these extended depths.
  • You could develop specific skills to expand your diving interests further. Imagine understanding more about wreck diving, driving a dive boat or becoming an underwater photographer. Check out the Skill Development Courses (SDCs) you can get involved in.
  • You could sign up for BSAC’s Instructor Foundation Course (IFC) to become an Assistant Diving Instructor, or develop your existing skills as an Open Water Instructor, or above, to become a Twin-set Diver Instructor.
