Training philosophy
Competence before certification.
Training is a rigorous process designed to build real competence and genuine self-reliance. Our objective is to develop divers who are qualified to plan and conduct safe, independent dives without relying on a guide. Cave, technical and CCR training require strong foundational skills, precise buoyancy, self-awareness and the right mindset.
Every training plan is adapted to the diver’s experience and demonstrated performance. The published number of days is a minimum based on performance appropriate to the course entry level. Additional classroom or in-water sessions may be required to meet the objectives and may carry an additional daily fee.
- Plan for full training days of approximately 8–10 hours.
- Allow at least two contingency days for advanced training.
- Advanced Trimix on open circuit and Advanced Mixed Gas CCR require a dry suit.
- SDI/TDI eLearning and manuals are not included unless stated in the booking proposal.
- Courses may be taught in English or Spanish.
- Private and exclusive groups are limited to a maximum of three students per instructor.

TDI teaching philosophy
Manage risk through judgment and execution.
Technical Diving International training is grounded in proactive risk management, practical real-world execution and continuous innovation.
- Risk mitigation over avoidance: inherent risk is addressed through planning, redundancy, teamwork and disciplined execution.
- Adaptive teaching: techniques are tailored to individual capability and to configurations such as backmount, sidemount and rebreathers.
- Judgment over memorization: training develops operational decision-making under real constraints.
- Progressive experience: divers consolidate skills and gain meaningful experience at each level before advancing.

NSS-CDS teaching philosophy
Cave education rooted in history and conservation.
The National Speleological Society–Cave Diving Section is committed to the safe and proper enjoyment of the cave environment. Its training philosophy recognizes that properly trained cave divers are more capable of protecting themselves and of reducing damage to irreplaceable underwater cave systems.
- Accident analysis: past incidents and fatalities are studied to identify and avoid recurring errors.
- Configuration-specific learning: realistic practice is completed in the equipment configuration the diver will actually use.
- Strict gas management: the Rule of Thirds reserves one-third for entry, one-third for exit and one-third for emergencies.
- Environmental conservation: fragile cave ecosystems, geology and wildlife are treated as essential parts of diver education.
- Standardized progression: buoyancy, trim, propulsion and guideline skills are consolidated before complex navigation is introduced.

One connected journey
Dive Rite México × ZOTZ.
Dive Rite México and ZOTZ share one purpose: helping divers go farther with the right experience, training and equipment. ZOTZ leads dives, courses and expeditions. Dive Rite México brings specialized equipment knowledge shaped by the same environments we explore. Together, they create one continuous path—from the first dive plan to demanding cave, technical and expedition objectives.

Why these standards matter
People protect what they love.
Our work promotes the importance of healthy ecosystems, from the sea to underwater caves. We take people to extraordinary places so they can discover, learn, care and understand why these environments must be preserved. High-level training, carefully designed expeditions, professional photography and filmmaking are tools that serve that purpose.
When a single day is not enough, personalized programs can combine training, lodging and transportation for five, seven or nine days according to the diver’s level and objectives.
