Recreationall TRIMIX

[Chris H]

I don't know of anyone who thinks the mix may change over time, and it has never, until now been presented that way. However, I would feel better if I and the divers on my team knew that what the mix sticker says is actually what is in the tank.

I was going to stay out of this, but there are a few other things.

I agree that you don't necessarily need to know ANY skills to understand a Nitrox or trimix table. However, you will be hard pressed to find somebody willing to dive with you if you are a cluster in the water.

I am very pleased with what I learned in Deco Procedures and Advanced Nitrox. I am glad Gert took the time to push us and make things go wrong during the dives so we had a chance to show we could handle the dive when things weren't going exactly as planned. Although Gert ultimately made the pass/fail decision you can bet your butt that I am a more confident diver after the class. Knowing that I can reach my own valves and that I know where my equipment and my buddy's equipment is makes me feel better anytime I'm doing a dive. That "filler" may very well save me or my buddy some day.

Take what you want from the whole DIR thing, but a lot of it makes tons of sense. There are plenty of places to get into that whole thing, we don't need it here too. You can read about something all day long, and spout off all sorts of other facts and figures to show somebody how much you know; but in the end what happens under water is what counts. It is pretty hard to switch to your deco gas if you can’t find it.

I am looking forward to the DIR-F course not because I want to tell somebody why they are doing it wrong, but so I can get pushed again. This training will never make me a worse diver.

Read all you want, but I read a book about how to drive an F1 car and I don't pretend to be an expert on that :
