Overview
The TDI Cave Sidemount Diver course develops the knowledge, equipment configuration, and operational procedures required to safely conduct cave dives using sidemount equipment systems within overhead environments.
Originally developed within cave-diving exploration communities, sidemount configuration offers:
- improved streamlining,
- enhanced gas redundancy,
- easier equipment management in confined spaces,
- and increased flexibility within complex cave environments.
This course teaches divers how to:
- configure sidemount systems for cave diving,
- manage independent gas supplies,
- maintain trim and propulsion efficiency,
- negotiate restrictions,
- and conduct cave penetrations using disciplined sidemount procedures.
Training focuses heavily on:
- buoyancy precision,
- streamlining,
- situational awareness,
- gas management,
- and cave-conservation discipline.
Drawing from modern exploration-oriented sidemount philosophy, divers learn to operate:
- efficiently,
- minimally,
- and with reduced environmental impact while maintaining high levels of redundancy and operational control within confined cave systems.
At N9BO℠, Cave Sidemount training progresses from:
- open-water equipment refinement,
- to real overhead cave-diving operations involving:
- navigation,
- restriction management,
- emergency procedures,
- and advanced team awareness.
This course is ideal for:
- certified cave divers,
- technical divers transitioning into sidemount systems,
- and exploration-oriented divers wishing to improve efficiency and flexibility within cave environments.

FAQ
Cave sidemount diving uses:
- cylinders mounted alongside the diver rather than on the back,
allowing: - improved streamlining,
- easier access to valves,
- and greater flexibility within confined cave passages.
Sidemount systems provide:
- excellent redundancy,
- efficient gas management,
- reduced profile in restrictions,
- and improved equipment accessibility.
These characteristics make sidemount particularly effective within overhead cave environments.
No.
This programme is:
- advanced overhead-environment training,
intended for: - already certified cave divers with prior sidemount experience.
Yes.
Training may include:
- confined passages,
- restriction-management procedures,
- and advanced streamlining exercises appropriate to student capability and cave conditions.
Many divers continue into:
- TDI Stage Cave Diver,
- TDI DPV Cave Diver,
- cave exploration projects,
- and advanced expedition cave diving.
