Intro to Tech



Course Structure and Duration

What you will learn:

Equipment Requirements (in addition to basic equipment)

The TDI Intro to Tech course introduces students to the world of technical diving. This course is designed as an introductory course to the TDI Advanced Nitrox course and the TDI Decompression Procedures Course. The objective of this course is to familiarize students with technical equipment configurations, to enhance open water diving skills (such as buoyancy, trim, and situational awareness), and to 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.
Intro to Tech may be combined with TDI Advanced Nitrox at the discretion of the instructor.
