HSE Closed Bell
Approximate Course Duration: 3/4 weeks
Free IMCA ALST (Assistant Life Suport Technician) included.
This is an advanced qualification which can only be undertaken by experienced HSE Part I, HSE Surface Supplied (Top-Up) or equivalent divers who have logged a minimum of 50 dives totalling at least 50 hours. The HSE Closed Bell qualification allows the diver to work to unlimited depth using oxygen and helium breathing mixtures (mixed gas) and saturation techniques.
The Underwater Centre is currently offering students the option to sit an IMCA standard ALST exam. Students wishing to do this will be given additional tuition.
The Underwater Centre also owns a saturation diving system located in Tasmania, Australia, which uses the same HSE syllabus, teaching materials and instructors but issues the Australian Diver Accreditation Scheme ticket ADAS 2158-4. This is recognised by the HSE for diving in UK waters.
