The Dive Rite O2ptima was one of the first fully closed rebreather systems we offered and continues to be a major unit within Australia. With rugged construction and continual development from the Dive Rite team, we’re pleased to be a service center and can offer full factory level support and training through all levels including instructor.

Dive Rite O2ptimaThe Entry Level Course

Training is offered through TDI Air Diluent Diver over a minimum of 6 days. There is no crossover course offered generally and no credit is offered for divers holding technical open circuit qualifications.

A typical training schedule :

  • Day 1 – Classroom Theory
  • Day 2 – Gear Workshop and Pool Training
  • Day 3 – Open Water Dives 1 & 2
  • Day 4 – Open Water Dives 3 & 4
  • Day 5 – Open Water Dives 5 & 6
  • Day 6 – Final open water dives & exams

Most training is conducted usually one on one but with a maximum of two students with Dive Rite O2ptima Instructor Trainer, Jason Blackwell. It is usually possible to structure a flexible course schedule (weather permitting).


Costs are payable in advance at the start of the course. We do not cut corners on your training and try to be as upfront with the costs as possible with no hidden extras.

  • Training Fee $2,200 inc GST
  • Boat Dive Costs estimated at $500
  • Manuals and Certification $100

Students will also need to purchase their sorb, oxygen and other consumables for the course as needed. We don’t offer cheap courses with poor outcomes and believe that when your life is potentially on the line, there is no substitute for good quality high end training from some of the most experienced rebreather instructors in the country. Our students leave our training being able to confidently dive, maintain and enjoy their rebreather.

What you will need

A fully working Dive Rite O2ptima, either current Divecan version or Hammerhead. Where a student is considering purchasing of a second hand O2ptima then you are strongly advised to contact us first well ahead of training so we can estimate the costs of bringing the unit into service and source any necessary spare parts. Training can only start once a unit has been brought into manufacturers non modified specifications.

If you are planning on purchasing a unit through us then it may be possible to hire an O2ptima for the course at $100 per day. We do not rent rebreathers outside a course environment.

For further questions on O2ptima training or purchase then contact us and we’re happy to chat informally through your options. We understand that buying a rebreather is a very large financial commitment and we can arrange try dives and spend time to talk through the options which are suitable to you.
