Who is the course for?

The ADAS part three course or air diving to 50 metres, is an internationally certified qualification having recognition from the international marine contractor’s association (IMCA.) This course is for aspirational divers who do not want to spend there career onshore on fish farms or living contract to contract as a onshore civil diver.

The SSBA to 50 M course is for the diver looking to become an underwater welder, salvage diver or just someone who wants to have the option to make big dollars when the chance arises.

The ticket will allow you to work in any country in the world and on any dive site if the depth is under 50 metres. Divers will also learn to be hyperbaric chamber operators during the course.

Finally the course is for those crazy enough to dare to become saturation divers as you must hold your ADAS part three ticket for at least one year before enrolling on this course.

Student Pre-Requisites

To enrol in our ADAS part three (Surface Supplied Air to 50 M) course you must first have completed our ADAS part two or international equivalent. Your ADAS tickets need to be current. For most students going directly from ADAS part two, this is easily met!

To meet the AS/NZS 2299.1 and ADAS requirements anyone who joins a course at CDA, or any other ADAS school is required to have a current first aid, 02 provider and CPR certification.
in general if the card has first aid on it, and the course was about a day long. it is likely this will be accepted. though if you are not sure if your first aid ticket is accepted, you can contact us any time to find out.

Before we can allow anyone to dive, they must hold an occupational dive medical. I am sure you have AS/NZS 2299.1 memorised now, and you guessed right. your medical, needs to be in accordance with this standard.
Because of this, the doctor who assesses you for medical fitness is required to be trained in hyperbaric medicine and certified as an occupational diving doctor.

you can find dive doctors using the SPUMS website below
