The TDI Intro to Tech course gives students a basic understanding of the world of technical diving. It is designed as an overview for the TDI Advanced Nitrox course and the TDI Decompression Procedures Course. The objective of this course is to familiarize students with technical equipment configurations, enhance open water diving skills (buoyancy, trim, and situational awareness), and introduce students to advanced gas-planning techniques within a no-decompression context. This course is strictly a no-decompression course. Students are permitted to use enriched air nitrox (EAN) mixes, provided the gas mix is within their current level of certification.
