When I went to the IANTD site you suggested I found the following information. <<< Normoxic Trimix Diver The IANTD Normoxic Trimix Diver program is aimed at those who wish to dive in the zone between 130 fsw (39 msw) and 200 fsw (60 msw) but are not comfortable doing so on air. The course uses normoxic mixtures and consists of 12 dives and one three (3) hour confined water session. Six (6) dives are on air to depths between 100 fsw (30 msw) and 130 fsw (39 msw) and six (6) dives involve practicing specified skills at depths between 30 fsw (9 msw) and 90 fsw (27 msw). All dives will be performed with two (2) stage cylinders. Four (4) Trimix dives are also made in the course with two (2) at depths up to 165 fsw (50 msw) and two (2) at depths up to 200 fsw (60 msw). This is an intense seven (7) day program enabling the graduate to be qualified to dive normoxic Trimix to 200 fsw (60 msw). It does not qualify the diver to use hypoxic mixtures to participate in dives deeper than 200 fsw (60 msw). The text for the course is IANTD's Technical Diver Encyclopedia, associated Technical Diver Workbook, Slides and newly developed Water-proof Tables. The prerequisites for this course require dives no deeper than 90 ft. and this course satisfies the prerequisites for more advanced trimix training. >>> Doesn't this simply reinforce my previous message? I read this as the instructor need never have the student go deeper than 101 ft on air. This seems reasonable to me for teaching introductory trimix. Take care and safe diving, Scott .. -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'. Send subscribe/unsubscribe requests to `techdiver-request@aquanaut.com'.
