Who this is for

This course is designed for active Advanced Nitrox Instructors or technical diving instructors who already operate confidently within a technical framework. Ideal candidates have personal experience with decompression diving and are ready to transition from executing these dives themselves to guiding, assessing, and taking responsibility for students doing the same.
 
It suits professionals who want to expand their teaching scope, strengthen their technical credibility, and offer a structured pathway for their students into decompression diving.

TDI Deco Procedures Instructor Course

Academic topics cover decompression theory, bubble formation, nitrogen absorption and elimination, CO2 toxicity, ascent rates, thermal stress, task loading, and gas planning using air, nitrox, and oxygen. Equipment, dive tables, oxygen-integrated computers, emergency procedures, and decompression protocols are also included.
 
Candidates must demonstrate gas analysis, pre-dive planning, staged decompression execution, SMB deployment, emergency gas-sharing, and multi-mix management. Course completion requires passing a written exam, a graded presentation, and a practical demonstration of teaching proficiency.
