Frequently asked questions
Does more oxygen mean I can descend farther?
No. It creates an oxygen-related depth constraint that must be respected.
Is a label enough to identify the gas?
No. Follow the analysis and verification procedures taught in the course.
Does this make me a gas blender?
No. Producing mixtures is a separate training and operational responsibility.
What should an Australian course quote include?
Ask for an itemised total covering learning materials, practical sessions, certification, equipment, boat or site fees and any extra training. Availability, duration and prices are centre-specific.
Where do I confirm the latest prerequisites?
