TDI - Whats it all about

[matt_unique]

I don't think DM skills have anything to do with tech skills. To go into the Deco class you should be comfortable with deep NDL dives, excellent buoyancy, etc. Tech is a different paradigm, especially in terms of gear used, than anything in rec.

The course materials were poorly written, but not a big deal.

I don't know if it is poorly written, but without a doubt it missing a lot of information
like Dive planning. I would also change the use of the US Navy air Tables to a
more conservative table, that not a big deal because most tech diver use some sort of deco planner. Anyway the handout could have been a lot better.

I'll third the comment that TDI needs a bit more information in the written materials and second the comment that they need something other than US Navy tables.

I thought my TDI deco procedures and Advanced Nitrox course was a little retro in that I had not used US Navy tables for years. The course was also lacking a bit in terms of gas planning with respect to accellerated deco. But, the instuctor recommended some supplemental IANTD materials and filled in the gaps.

But the in water portions of the course were excellent.

I think the course would be better if the adv nitrox and deco proc were integrated. There is quite a bit of overlap and one has to be designed so that it may be taught without the other.

Whilst this is theorectically true and i admit there are some 60 dive DM wonders out there, When i took my deco procedures course there was a total group of 7 split between instructors, after two days the three DM qualified divers were streets ahead in terms of skill level. as toy say if you are comforatble with your skills it shouldnt be a problem for anyone.

Just curious....has anyone besides myself taken the dsat tech deep class. I took it about a year and half ago and it really rejuvinated my love of diving....like i started all over. I do believe that the instructor makes or breaks the class. I do like the way TDI breaks up all of the learning (deco proc, adv eanx). Not sure why dsat did not do this. It does make it a little pricey to do all in one shot. I did like the text for the dsat class compared to the tdi book. Seems that it had a lot more information. I am thinking of taking the trimix class but not sure of the dsat trimix class (I know nobody who has taken it besides the instructor who trained me). Has anyone taken this version. Maybe i'll wait until I have rebreather training before I take the trimix class. Kinda wish I had gone that route from the begining....think I would've saved some cash. It is definately more cost effective to run helium on a rebreather than open circuit.

What does a Trimix fill cost?

What does a Trimix fill cost?

Depending on the % of helium, but in average dive shop will
charge anything between 60 cents to 1$ a cubic feet in the US and Canada.
So you could spend as much as 100$ to fill a large set of doubles.
Some other place in the world you can pay a lot more.
