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.
