To become a saturation diver you must first qualify and work as
an air diver. Once you have a set amount of logged dive hours,
working in surface supplied equipment in open water, you can
complete a training course to gain your saturation (also known as
mixed gas or closed bell) diving certification. The Underwater
Centre in Tasmania provides ADAS diving certifications in both air
and saturation diving, and The Underwater Centre in Fort William
provides HSE diving certifications in both air and saturation
diving. Both ADAS and HSE certificatoins are internationally
recognised, allowing you to work anywhere in the world.
