Cavern diving introduces the discipline of overhead-environment procedures while sharpening the fundamentals serious divers depend on: buoyancy, trim, propulsion, awareness, gas management, communication and team control.
The course is taught as a PADI Cavern Diver Specialty and follows current PADI standards, site rules, conditions and instructor judgment. Where additional cave-diving best practices are introduced, they're used to increase conservatism and competence, not to exceed the limits of the certification.
Training focus
Technical configuration and pre-dive procedures
Trim, buoyancy and controlled non-silting propulsion
Guideline and reel procedures
Light and team communication
Gas planning and emergency awareness
Cavern-zone limits and overhead discipline
Operating limits taught in the course
Remain within the cavern daylight zone and keep a continuous guideline to open water.
No-decompression dive planning only; stay within computer or table limits.
Rule-of-thirds gas management as a maximum penetration allowance, not a target.
Conservative depth and penetration limits based on PADI standards, site rules, visibility, gas supply and diver performance.
A three-minute safety stop when conditions permit.
End the dive for primary light failure, gas concerns, loss of visibility, loss of team control, equipment issues, or any diver calling it.
What you'll learn
Cavern versus cave: certification boundaries and prohibited cave-diving activities.
Cave geology and terminology: solution caves, springs, siphons, sinks, cenotes and sumps.
Equipment configuration: streamlined backmount, no dangling equipment, redundant gas delivery, lights, reels, cutting tools, bolt snaps and wet notes.
Buoyancy, trim and propulsion: horizontal trim, distributed weighting, frog kick, modified frog kick and modified flutter kick.
Communication: hand signals, light signals, wet notes and touch-contact procedures.

Open to certified divers. Participation is subject to prerequisites, instructor approval, site conditions and park rules. Cavern diving is overhead-environment training. Certification is earned by successfully completing the required skills and standards; it isn't guaranteed by attendance. This course does not qualify divers for cave penetration, complex navigation, decompression diving, restrictions, jumps, gaps, circuits or traverses.
