HYPOXIC TRIMIX 100m

The Hypoxic Trimix course is the top of the Ocean Dreams technical programme, with training dives to 100 m using hypoxic bottom mixes, travel gas, and high-oxygen decompression gases. Hypoxic mixtures — those with less than 21% oxygen — are required at these depths where surface-normal oxygen percentages become toxic.

Gas planning at this level involves managing three or more distinct mixes across the dive profile: the hypoxic bottom gas, a normoxic travel gas for the ascent phase before the decompression stops, and high-oxygen decompression gases for the stops themselves.

Entry requirements reflect the seriousness of the depth: 150 logged dives, at least 30 deeper than 30 m with two decompression stops, at least 10 deeper than 50 m with two gas changes, plus Normoxic Trimix 67m and Oxygen Provider. This is not a course for anyone who hasn't worked through the complete preceding technical pathway.
