Hi Scott from another Scott, again, Once again I do not understand your most recent message. My posting said << these agencies no longer require deep air certification as a prerequisite to studying trimix diving; either by eliminating the requirement outright or by leaving it to the discretion of the instructor. If you have any contradictory information, I would appreciate your bringing it to my attention. >> And your recent posting to me, while interesting, does not seem to shed any additional light on this statement. Recall that I said they no longer REQUIRE deep air training before trimix, and I still stand by that statement. Recall also please, that my statement was made in answer to TClagett@ao* writing << ... considering some of the dumb shit the cert agencies make you do prior to learning trimix. >> And once again I say << If you have any contradictory information, I would appreciate your bringing it to my attention. >> Take care and safe diving, Scott In a message dated 5/26/00 11:58:04 PM, cobber@ma*.ci*.co* writes: << Who says you need to be certified to use trimix? >> In a message dated 05/27/2000 5:19:15 AM EDT, ScottBonis@ao*.co* writes: << Is this a particularly bright comment?

If you were teaching your teenager to drive would you take him/her and get them drunk offf of their ass and take them driving just so they would know how it would feel drunk. This is why you shouldn't drive drunk, see how bad you wrecked the car.

(And I suspect that the WKPP project can take credit for having had a lot to do with this.) Accordingly, these agencies no longer require deep air certification as a prerequisite to studying trimix diving; either by eliminating the requirement outright or by leaving it to the discretion of the instructor. If you have any contradictory information, I would appreciate your bringing it to my attention. In a message dated 5/27/00 6:37:09 AM, TClagett writes also: << Most of the people on this list were diving trimix before any agency would even condone it much less certify you to dive trimix. >> I imagine that given the number of people on this list, their average trimix diving experience, and the number of years that trimix diving certifications have been available, I find it difficult to accept this statement as valid.

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.

The IANTD Deep Air Diver program trains divers in skills, performance, theory and planning of deep dives. This program remains within the commonly practiced depth of 130 fsw (39 msw). It is the first sanctioned program to provide proper international training in safe deep diving skills and performance. It is recommended that this program be taught in conjunction with the IANTD EANx Diver prog ram. Advanced Deep Air Diver This program has been designed to provide safe training to those divers who carry out diving to depths greater than the commonly practiced depth of 130 fsw (39 msw). The IANTD Advanced Deep Air Diver program provides training to 160 fsw (49 msw). It is a tightly supervised program concentrating on safety and control of oxygen and narcosis risk. This program also provides training in many advanced forms of diving technique. 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.
