Move beyond standard cave limits and plan longer, more complex dives
TDI Stage Cave Diver Course
Advanced Cave Gas Management
Extend your cave diving range with the TDI Stage Cave Diver course in Phuket, Thailand. This advanced program trains certified cave divers to safely use stage cylinders to increase penetration distance while maintaining strict gas management and safety procedures.
The TDI Stage Cave course is a key step toward exploration-level cave diving, where efficient gas logistics and disciplined planning are essential.
What Is the TDI Stage Cave Diver Course?
The TDI Stage Cave Diver course teaches divers how to plan and execute cave dives using additional cylinders (stage bottles) that are strategically placed and retrieved during the dive.
This allows for:
- longer penetration distances
- increased gas reserves
- more flexible dive planning
However, it also introduces:
- greater complexity
- increased task loading
- stricter procedural discipline
Why Use Stage Cylinders in Cave Diving?
In standard cave diving, your range is limited by the gas you carry.
Without Stage Cylinders:
- limited penetration distance
- strict gas constraints
- shorter exploration range
With Stage Cylinders:
- extended penetration distance
- increased safety margins
- ability to stage and retrieve gas along the route
👉 Stage diving is what makes serious cave exploration possible.
How Stage Cave Diving Works
Stage cave diving is not just carrying extra tanks—it’s a structured system.
Divers learn to:
- plan where to place stage cylinders
- drop cylinders at specific points in the cave
- mark and identify cylinders correctly
- retrieve cylinders during exit
- maintain proper gas reserves at all times
Precision and planning are critical.
