PADI DSAT Trimix Course

PADI Tec RecThe PADI DSAT Tec Trimix course completes your training as a full Trimix Diver. The course refines the skills learned in the Tec Deep Diver course, then expands upon them with knowledge application through sequenced training dives. The dives begin in limited open water with Open water dives follow, progressing from air/enriched air dives to trimix dives.

The dives apply material from previous knowledge development and build upon previous skill development. You will first develop skills independently, then integrate and apply them in simulated trimix dives, and finally apply them in actual trimix dives.
