Basic Decompression.
Planned decompression on a single-tank recreational rig, plus one stage. A gentle, controlled introduction.
What this
course is.
Not every diver wants to commit to a twinset before they understand what deco actually feels like. This course gives recreational divers a structured first taste — planned staged decompression on their existing single-tank rig with a single stage bottle, capped at 40 metres and 15 minutes of deco. Most divers move on to Decompression Procedures afterwards. Some do not — and that is fine.
Honest about
the cohort.
- Recreational divers curious about decompression diving without yet buying a twinset.
- Divers who want to extend bottom time on local wrecks within strict limits.
- Anyone wanting to evaluate whether full tech is for them before committing.
Drilled until
it's boring.
Skills are not a list to tick — they are habits to build. We drill them on land, drill them in the shallows, then take them into the dive.
Single-tank + stage
Routing, clip discipline, switch protocol with one extra cylinder.
Planned short deco
Up to 15 minutes of stops. Run-time. Conservatism.
Best-mix on recreational gear
EAN 32 to 40% nitrox as your back gas or stage.
Stop discipline
Buoyancy and trim on stops. The same dive every time.
Lost-gas contingency
What happens if you cannot reach your deco gas. Walk through it.
Honest evaluation
At the end, you know whether you want to step into a twinset next.
