The IANTD Normoxic Trimix Diver program is aimed at those who wish to
dive in the zone between 39mt (130 fsw) and 60mt (200 fsw) but are not
comfortable doing so on air.
It can be taken in lieu of Technical diver. The instructor will extol

During the course you will complete the IANTD
Normoxic Trimix Diver theory with your instructor, including content on
oxygen exposure tracking for technical & gas switch dives, equipment
set up & configuration, physiology & decompression as well as a
gas switch decompression dive planning workshop. All lectures completed
with IANTD Normoxic Trimix Diver course specific slides pertaining to
the theory in the IANTD Normoxic Trimix Diver Student Kit and materials
in the Encyclopedia of Technical and Mixed Gas Diving.
You will then move to a suitable confined water site
where you will demonstrate your ability to perform the skills required
to safely conduct decompression, gas switch dives using a twinset and
stage cylinder. This session also gives you the perfect opportunity to
touch up any skills which may have become rusty since your last course.
will complete at least four training dives with a minimum of 220
