Knowledge development
IncludedTDI course academics/knowledge development are included and integrated with instructor briefings and land drills.
Build overhead-environment fundamentals in a 3-day TDI Cavern Diver course with academics, land drills and four cavern dives at two cenote sites.
TDI course academics/knowledge development are included and integrated with instructor briefings and land drills.
Configuration checks and land/confined drills establish guideline, propulsion, communication and emergency procedures before cavern penetration.
Four cavern training dives are conducted across two different cenote sites.
Cover cavern policy, gas planning, equipment, communication, guideline procedures, propulsion and emergency drills.
Apply guideline, trim, propulsion, light/communication and controlled-exit procedures at the first cenote site.
Repeat and integrate the skills at a second site with scenario-based problem solving and final assessment.
Training schedule: Three-day technical course with academics/drills followed by four cavern dives across two cenote sites. Exact cenotes are selected for training objectives and conditions.
Open-water logistics: No ocean boat is required; Xico arranges ground logistics to the selected cenote training sites.
Schedule note: Start dates are available subject to instructor availability, student readiness and operational confirmation.
Certification requirements: Training is conducted and evaluated by an appropriately qualified instructor for the agency and course. Certification or recognition is issued only after the applicable course requirements are successfully completed.
The TDI Cavern Diver course from Playa del Carmen is Xico’s entry point to formal overhead-environment training. It teaches the discipline, guideline work, propulsion and emergency procedures needed inside the daylight zone of a cavern.
The current Xico program uses three days so equipment configuration, gas planning, land drills and four cavern training dives can be developed progressively instead of compressed into a quick cenote tour. The dives take place at two different sites.
Cavern is not unrestricted cave diving. Training stays within natural daylight, uses a continuous guideline, follows conservative gas rules and avoids decompression and restrictions. Those limits are part of the skill, not obstacles to it.
The course builds precise buoyancy, trim, anti-silting propulsion, line awareness, light communication and team procedures. Divers who later want Intro to Cave or Full Cave training start from these disciplined fundamentals rather than learning them after penetration has already increased.

No. Cavern training remains in the daylight zone with a continuous guideline, no decompression and no restrictions. It is an overhead-environment foundation course and does not grant unrestricted cave-diving privileges.
Minimum age is 18, or 15 with the required parental consent. You need Open Water Diver or equivalent and at least 25 logged dives. If planned training goes deeper than 18 m / 60 ft, Xico also requires proof of suitable deep training/experience.
Cavern training requires redundant lights, line/reel tools and an appropriate configuration. Xico provides course-use torches, guideline/reels/markers, tanks and weights as described; full personal scuba-gear rental is separate if you need it.
Yes. Xico can run its courses with one booked student, so you do not have to wait for us to fill a group. Your requested start date still needs instructor and operational confirmation.
Scuba students complete the required diver medical screening. Depending on your answers, physician approval may be required before in-water training. Any external physician or consultation cost is separate unless a course page explicitly says otherwise.
Send us your preferred start date. Xico will check the appropriate instructor, training schedule and any required training logistics before confirming the course. Start dates are flexible, but a website request is not an instant booking confirmation.
