As an aside, nitrox use was also long-touted as being somehow "less fatiguing" than that of breathing conventional air; though, I have used it, off and on, since the early 1990s, when applicable, and have experienced no difference whatsoever -- that is, with the exception of a slightly lighter wallet . . .
I am afraid I don't understand this. I am evidently being unusually dense today.Actually, @Storker
Why DO dive computers let you adjust for salt water or fresh water? Yes, there is a difference in density, but all deco calculations are based on actual measured ambient pressure, right? If you were diving in mercury or using it in a hot air balloon, wouldn't you want the DC to know what the depth was in ATA, not in feet or meters? And this implies that adjusting your DC for salt or fresh water introduces an error rather than corrects for one.
In past threads, most people say a good way to see the difference is a week of diving on a liveaboard.perhaps if i dived more it would be a bigger benefit ?
if we are diving fresh water and the gauge reads 34 feet, our depth gauge (being calibrated for sea water) "thinks" we are in 33 feet of sea water and so will read 33 feet. (10meters)
so in reality, we can do all calculations "as if" we were diving sea water.
my only point was that the actual manual arithmetic that we teach on a white board in class is different for sea water than it is for fresh. this should be obvious.
It's kind of a secret code. Like Pig Latin.I hate when I see 33. Meters Vs Feet. Even though it is as simple as to divide or multiply by 3. I know that you guys are the kings of the world but why can’t you use metrics like the rest of the world ?
It is partially a joke. I have never seen a dry suit just pictures, movies and people are like the Michelin bibemdum wearing it. Very different with the freedom of movement that one has with a wetsuit.What does this mean?

The computer's depth sensor measures ATA, and the computer's software converts that to feet or meters for our benefit. If it is calculating NDLs, etc., it is doing that based on the pressure, not the numerical depth conversion. During my dive, my computer will give me a warning if I am too deep for the MOD of the gas I am breathing. If I am using 32% in fresh water at my altitude, my computer will be just fine with me breathing it at 115 feet, but it would be giving me a warning if I were in the ocean.
