NAUI Tech 3 Trimix

The Technical Level 3 (Tech 3) course is the culmination of a series of three courses designed to establish technical diving excellence and facilitate deep, mixed gas diving. Emphasis is placed on aggressive diving profiles including advanced decompression theory, advanced gas mixture/management, control over extreme exposures to Oxygen and proficiency in the use of a DPV for propulsion at depth. This course is heavily experience-based and deals mostly with the practical implications of deep diving; divers are expected to be capable technical divers.
