Recreationall TRIMIX

[puddlejumper1]

A lot of good points that I agree with. I agree that Deep Air Decompression / Advanced Nitrox is a waste and even dangerous to teach. I agree that having a class for recreational mix is not a bad idea. i do not like palms of any type (Ihave less than that into my laptop) and will stick with V-Planner. I have been daeling with gases longer than they have been used for mainstream diving and can tell you from experience that most of what the dive industry teaches is B.llSh.t. If even half of the mantra was true there would have been mass deaths in the welding industry going back over 50 years. ( I just love when someone tells me that a tank can only be sent to Hydro testing once for + rating since my O2 tanks have been + rated since the 40's when they were manufactured.) The common misconception that a mix may change overtime is a trivial falsehood. Show me one tank and I will bow to the gods. But after literally thousands of tanks having the right mix for years (diving is not the only industry to use mixes and is one of the newest) I can tell you that it just can not happen. That said if a tank is seriously mixed wrong than you could conceivably get a layering of gasses (not unlike a layered drink) but really since all the gases have different weights it would not stay that way. But I have never seen this happen yet and do not think it is likely. I have seen more where the initial read was off someone compensated and then had to dump because the mix came up strong. I have tanks that are sitting around the shop for over a year. We use this in some of our diagnostic equipment and have nevr had a problem with the mixes.
