TDI Advanced Nitrox Course Completed

Technical Divers advance to Advanced Nitrox Diving in Thailand

Koh Tao, Thailand

Big Blue Tech celebrates the graduation of Jennifer Cronin and Johan Arsborg from their TDI Advanced Nitrox course conducted by TDI Technical Instructor Andrew Cavell on Koh Tao Island off the coast of Thailand over 3 days with 4 dives and academic theory presentations.

This is the first (1st) stage of training in the series of TDI’s tech diver development program. The objective of this course is to train the divers in the benefits, hazards and proper procedures for utilizing Enriched air nitrox twenty one (21%) percent through to one hundred (100%) percent oxygen for dives not requiring staged decompression. To a depth of forty (40) msw, one hundred thirty (130) fsw.

The course enables the certified diver to use enriched air nitrox to extend their no decompression limits by swapping gas to higher blends as the dive continues and becomes shallower. This gives the diver no decompression obligation and longer deeper dives than experience before.

This course is also a pre-requisite to decompression diving which the students will start in a few days.
