Extended Range Diver
Deep-air diving to 55 metres with full staged decompression.
About The Course
Extended Range pushes staged-decompression diving to its deep-air limit — around 55 metres — with multiple decompression gases and longer, more committing run-times. It is the natural bridge between Decompression Procedures and trimix.
You learn to plan and manage deeper dives on air with accelerated decompression, building the gas-management discipline and ascent strategy that trimix will later demand.
