Overview
The TDI Intro to Tech course introduces divers to the world of technical diving by focusing on equipment configuration, precision skills, and advanced dive planning.
This program is designed as a bridge between recreational and technical diving, refining core skills such as buoyancy, trim, and situational awareness while introducing technical equipment and procedures. 
All training is conducted within a strictly non-decompression framework, allowing divers to develop technical discipline and control without the added complexity of staged decompression. 
At N9BO℠, this course is where divers transition from recreational habits to technical standards: focusing on precision, consistency, and system-based diving.
