The TDI Intro to Tech course is a foundational program designed to introduce recreational scuba divers to the equipment, techniques, and mindsets of technical diving.
It acts as a bridge between recreational diving and advanced technical courses, focusing heavily on precision buoyancy, perfect trim, and specialized gear configurations without exceeding sport-diving limits.
1. Equipment Configurations
Twinsets & Doubles: Learning how to manage and wear twin cylinders or sidemount configurations.
Redundancy: Introduction to long-hose regulators, backup necklaces, and technical wing/harness systems.
Wetnotes & Accessories: Integrating data slates, technical tools, and Surface Marker Buoys (SMBs) into your gear.
2. In-Water Skills
Buoyancy & Trim: Mastering the ability to hover perfectly horizontal and motionless without moving your hands or shifting depth.
Advanced Propulsion: Learning precision kicks such as the frog kick, modified flutter, helicopter turns, and backward finning.
Safety Drills: Practicing valve shutdowns (drills to isolate gas leaks), gas-sharing scenarios via the long-hose (S-drill), and controlled ascents.
3. Theory & Dive Planning
Gas Management: Understanding gas matching for buddies, calculating surface air consumption (SAC) rates, and emergency gas planning.
Situational Awareness: Shifting focus from just yourself to true team-based diving awareness.
