IncludedRequired TDI Advanced Nitrox and Decompression Procedures learning materials / eLearning for the combined Xico program are included.
Five-day all-inclusive TDI Advanced Nitrox + Decompression Procedures program with a minimum of six technical training dives across four cenote days and one ocean day.
Required TDI Advanced Nitrox and Decompression Procedures learning materials / eLearning for the combined Xico program are included.
No separate pool session is required; land drills, equipment work and in-water technical skills are integrated into the five-day training program.
Minimum six training dives when TDI Advanced Nitrox and Decompression Procedures are taught together; more may be conducted at the instructor’s discretion. Combined-course maximum training depth is 45 m / 150 ft under the applicable TDI standards.
Equipment assessment, Advanced Nitrox academics, gas analysis/planning and foundational technical drills before the in-water progression.
Develop precise buoyancy, trim, shutdowns, team protocols, gas management and controlled technical-dive procedures.
Integrate staged-decompression planning, ascent control, decompression-cylinder handling and gas-switch procedures in a controlled training environment.
Repeat and integrate the combined course skills, including contingency planning and instructor-selected technical scenarios.
Apply the combined Advanced Nitrox and Decompression Procedures skills in the ocean and complete remaining course performance requirements.
Training schedule: Five-day technical program using four cenote training days and one ocean training day. Exact dive distribution, depths and sites are performance- and conditions-dependent.
Open-water logistics: The first four days use ground transport to the selected cenote training sites; Day 5 uses Xico’s confirmed ocean boat operation.
Schedule note: Five consecutive or agreed training days are confirmed with Xico according to technical-instructor availability, student readiness, cenote/ocean operations and conditions.
Certification requirements: Training is conducted and evaluated by an appropriately qualified instructor for the course agency.
This five-day Xico program combines the two TDI courses that form the foundation of planned decompression diving: Advanced Nitrox and Decompression Procedures. The training develops gas selection and analysis, oxygen exposure management, technical equipment configuration, decompression planning, gas switching and disciplined staged-ascent procedures.
Current TDI standards require at least six dives when Advanced Nitrox and Decompression Procedures are taught together, with additional dives at the instructor’s discretion. Xico uses four cenote training days and one ocean training day so skills can be repeated in different environments rather than compressed into the minimum number of sessions.
The combined standards allow training to a maximum of 45 m / 150 ft. Actual depths remain an instructor decision and depend on the specific exercise, student performance, gas plan, environmental conditions and any more restrictive limit that applies to the training dive.
The confirmed Xico program includes the technical training configuration, cylinders, required breathing/decompression gases for the planned dives, TDI learning/certification processing and the scheduled cenote/ocean logistics. The instructor confirms the final configuration and gas plan before training begins.

For the combined program you must be at least 18, hold TDI Nitrox Diver or an accepted equivalent, meet the Decompression Procedures prerequisite of SDI Advanced Adventure Diver, Advanced Diver or an accepted equivalent, and show at least 25 logged open-water dives. Xico also evaluates buoyancy, trim, gas planning, medical screening and technical-equipment readiness before confirmation.
Current TDI standards require at least six dives when Advanced Nitrox and Decompression Procedures are taught together, with more dives allowed at the instructor’s discretion. Xico delivers the program over five training days across four cenote days and one ocean day. The exact dive distribution is performance and conditions dependent.
The combined TDI program permits training to a maximum of 45 m / 150 ft under the applicable course standards. Actual training depths are selected conservatively by the instructor according to the planned exercises, student performance, gas choices, site conditions and the more restrictive limit whenever another training requirement applies.
Xico sells this five-day program as an all-inclusive technical course. The confirmed training plan includes the technical scuba configuration required for the course, cylinders, required breathing/decompression gases for the planned training dives, course materials/certification processing and the scheduled cenote/ocean training logistics. Xico confirms the exact configuration before the start date so it matches the instructor’s plan and the student.
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.
