The TDI Full Cave Diver Course has a duration of 4 days (and a minimum of 8 cave dives), if combined with the TDI Intro to Cave diver course with CDT Mexico directly, and immediately after. An additional day of training for reviews and checks is required for students coming from another instructors/area and who wishes to continue their training with CDT Mexico. In this case the minimal duration is 5 days. The duration of the course, and the number of dives necessary are performance based. We train until you're adequately prepared to plan and dive in an autonomous manner with a teammate without supervision. Merely performing skills is not enough. Students must show an overall high level of mastery in the following fields: - fundamental skills (breathing, buoyancy control, trim, propulsion) - dive planning (maps readings, orientation and route, gas needs & limitations, cave conservatism) - awareness (self, global and situational awareness) - team’s dynamics (active & passive communication, positioning, pacing & placing) - mindset (positive non-egoic motivation, cave conservatism, cave etiquette, risk assessment) - stress recognition & management (capacity of acting rationally under stress) The evaluation of this qualities of course is quite relative and reflects the perception of the instructor. CDT Mexico instructors are very experienced and specialized in teaching cave divers. We are caring and conscious of the efforts provided by our students during this demanding course(-s). Surely we put the bar quite high, but we also help and direct you to reach it in the shortest possible time, always keeping the quality and the safety at the centre of our attention. “Train Hard – Dive Easy”
