Trimix 2 with Andrew Georgitsis report,
Around Christmas last year three fellow divers and I decided that we wanted to take our Tech 1 level of diving, a step further. Two of us had GUE Tech 1 training and all of us had full trimix training from other agencies such as IANTD, TDI, and ANDI.
Our initial thoughts were that we would enroll in a GUE Tech 2 course but doing so raised several issues. The first issue was that our instructor choices were limited. I don't care what people say but it is the instructor and not the agency that makes the course. Of course the constraints that agencies place on their instructors in terms of curriculum, standards, etc., do play a significant role, but it is my belief that in training of this nature, the instructor becomes the primary consideration. Our second concern was that we wanted comprehensive training that would result in us feeling trained and competent to conduct dives at 250 ft level with multiple deco and stage bottle configuration after the successful completion of our course. Here we identified what we felt was a flaw in the current GUE Tech 2 curriculum.
At the end of the GUE Tech 1 course a student is left with tools to become more proficient in diving back-gas and ONE AL40 deco bottle (50%). The student is not shown two-bottle work, let alone instructed on it. Moreover, they are never shown the mechanics of using a stage bottle and the inherent complexity this creates. For people who think that it is simply a matter of using a bottle under their arm....well, they don't know what they don't know. This raised what was in our eyes a major flaw in the standard Tech 2 curriculum: that is, even if a diver has all the single bottle, Tech I, deco skills completely solid, how do they go from one deco bottle with a 150 range to three bottles, a 250 ft depth range, and the ability to deal with all the failure implications of having 5 regulators to keep track of, your buddies five regulators, deco, situational awareness, environmental conditions, etc in a five day period? Only two things can occur...the diver is going to fail the course or they end up passing a severely watered down version of it. I believe that it is impossible to teach and evaluate that set of skills in five days.
Enter Andrew Georgitsis and his approach to teaching this material.
In January 2007 we set up a series of two to three day weekends and started our training. We started with a full day of Ratio Deco also known as 'Deco on a fly'. Amazing stuff...for those who think that this simply about 1:1, 1:2, 1:3 ratios, you are sadly mistaken. We sat through hours of theory, both past and present, deco modeling, deco set- up strategies, gas considerations and a lot more.
This was followed by two full days of two-bottle work. The shortest dive was 140 min in 46 degree water. For those YouTube show offs...give this a try after two hours in 46 degree water with thick gloves and we'll see what the bottle whipping looks like!
Six weeks later, we did a couple of check out dives to the Tech 1 level...150 ft 25 min, but this time with two deco bottles, followed by more Deco theory.
Six weeks later we started three-bottle work with the shortest dive being 150 min. Please keep in mind...if you carry three bottles you have to be able to proficiently handle six bottles...yours and your buddies. Give that a try...and remember that now you have two leashes! On that same weekend we did two experience dives with a max depth 170ft but this time with three bottles.
Six weeks later we started with two full days of ascent failures with three bottles or more, depending on how many failures your buddy had. Now you had ten regulators to keep track of, a deco schedule, up-line etc. I think you get the idea. Couple this with running a line on a bottom with failures in the 90-100 range and you really have your hands full. Despite all the punishment it was great fun. It showed all the aspects that you have to keep track of. Finally, the payoff was our experience 240 dive the following day that despite current and questionable viz felt like one of the best dives ever. We all believed that the reason this dive felt that way was that it had been earned through the multiple days of training that came before.
Everybody can draw their own conclusions. I'm not here to advocate a new platform for teaching or promote Andrew G. (like he needs it anyway ). I'm simply describing our experience. That being said, would I ever take a course that runs in consecutive days...no bloody way! Our experience has been that you truly need to absorb and work on the new skills that are introduced to you during a course as demanding as this was. I would like to encourage everybody who is thinking of advancing their diving training to talk to your instructors and see if you can spread your training out as we did. The time between the segments that allows you to practice the new skills is, without exaggeration, invaluable. As a Trimix instructor myself I have adopted the same approach of spreading the training over multiple weekends to allow students to practice newly learned skills. The feedback from students is overwhelmingly positive. They dont feel rushed and in addition there is time to clarify any questions or issues identified during their practice period.
We also need to pass on a big THANK YOU to Andrew G. who tirelessly provided us with exceptional teaching and instruction. It was his suggestion to spread the training over multiple periods to ensure the highest quality of training available. Throughout the duration of the course Andrew was able to identify our weaknesses very effectively and focus the training accordingly.
Happy diving,
