Intro to Tech TDI
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.
This course is strictly a no-decompression course; students are allowed to use enriched air nitrox (EAN) mixes, as long as the gas mix is within their current certification level. Intro to Tech may be combined with TDI Advanced Nitrox at the instructor's discretion.
Daily rate per person
