ADAS Part 2:

Surface supply Diving to 30 m

The next stage.

After you’ve completed your ADAS Part 1 commercial dive certificate, this 4-week module allows you to dive to 30 metres on surface supply breathing apparatus (SSBA) or air sent down from the surface via an umbilical line.

This is the basic working commercial divers qualification. You will wear a rigid helmet or a semi rigid bandmask, learn construction techniques such as rigging and moving heavy items underwater, underwater cutting and welding and how to safely use hydraulic and pneumatic tools.

Please note:
You cannot complete this qualification unless you already have an ADAS Part 1 or are completing it with a Part 2 Qualification.


You must:

  • Already hold a Part 1 or be pursuing it as part of a combined course.
  • All entry requirements for Part 1 must still be current.

Please bring all your original entry requirement paperwork to Day One of your course, including your USI number.

The enrolment process.

  • Use the Contact Us form or call for further information and enrolment details.
  • You have secured your place on your selected course once we’ve received your enrolment form and deposit.
  • We’ll send you a confirmation of receipt and an electronic copy of our handbook. This gives you all the information about the course, accommodation, what is expected of you and what you need to bring. We recommend you print it off and bring it with you to your first class.
  • Important Note:
    You don’t need to have all your entry requirements upon enrolment. However, it’s up to you to make sure you’ve met all these requirements before starting your course.
