ADAS Part Three Graduate Feedback

I really enjoyed my experience training at CDA, beauty point, Tasmania. The trainers and staff are friendly and very knowledgeable. The Commercial Diving courses are well put together with lots of hands-on experience. If you were considering this line of work, I would definitely consider undertaking the training here. The facility, equipment and training that is offered and available to students is nothing short of amazing. The Saturation barge is an experience within its self. I'd doubt you'd get this type of experience anywhere else in the southern hemisphere. I'd like to thank thank them for delivering a strong, realistic program for preparing students (us) for the industry. Many thanks and Cheers.

ADAS Part Four Closed Bell (Saturation) Diver

ADAS & IMCA Part Four Closed Bell and saturation divers graduating

ADAS Part Four (Closed Bell to 300M)

ADAS Part Four is the most advanced of all commercial diving courses and allows graduates to dive up to 300 Metres in a closed bell.

 It is a diving technique that allows divers to reduce the risk of decompression sickness when working at great depths for long periods of time. Closed bell diving involves working and living in a pressurised environment either on land or underwater.

ADAS Saturation Diver Feedback

"I have known and worked with the main instructors for over 16 yrs as a saturation diver, they have trained me my whole career and are by far the best in the industry. No other training centre has the facilities, courses and knowledge to get you where you want to be in the industry."

Commercial Diving Supervisor Feedback

"I’m part way through my trainee supervisors course. The one thing I was fearful about was the physics component. I’ve spent a lot of long nights trying to get my head around all the formulae needed. Today in a matter of hours I have had everything explained in such a way that I’m confident that I’ll pass. Best teachers teaching best practice. Don’t waste your time going anywhere else"
