nitrox downsides

[Blackcrusader]

There is no downside to using nitrox until gas density and narcosis becomes an issue around 100ft at which point trimix should be utilized.

In a near 40 years of diving I've never used Trimix for dives deeper than 33m. It's not necessary nor required. It's also not available in many places. Around 30% of my dives have been deeper than 30m

I scuba dived yesterday is that close enough?

I live 150 meters from water's edge and will be doing a 2 hour dive tomorrow (as I normally do), does that count?

Nope. You and me and everyone else)has to dive every day and not drink or smoke and look cool without using nitrox in order to be qualified to reply to @Scuba-guy's posts.

I do sort of agree with the no smoking rule though. Especially in confined spaces on dive boats where you can't get away from it.

They will pay for nitrox but won't tip the DM, so it's a way to milk them for more cash.

tips are a gratuity and not mandatory, In Japan tipping is seen as an insult. No requirement to tip anywhere really. In places like Philippines I wont tip cash but buy a lechon pig so all the staff & boat crew and guides get a good feed in.

Getting a little narcosis actually feels good so why avoid it?

You "must" monitor your oxygen exposure.

Not really.

The only downside of nitrox is that you need to know how to use it safely.

But the same can be said for scuba diving in general.

There is no downside otherwise.

This is the best answer of any.

More expense

Not always.

I too get less fatigued after a full day of diving with Nitrox

YES!

Is it possible to exceed 24hr CNS clock with just recreational diving, using only 32% Nitrox?

Answered in the next two quotes.

For rec diving, it's possible but quite hard.

Realistically, no. This is not a real world problem. You would really have to work hard to get anywhere close.

an average depth

Average depth has nothing to do with Narcosis or Toxicity, no matter how many time it is said.

I scuba dive more than any of you do, around 2 and a half hours per day150 days a year and my opinion is its just for dumb suckers, wanna be scuba nerds and the like. Just something to sell to the dumb tourists. They will pay for nitrox but won't tip the DM, so it's a way to milk them for more cash.

This is an overwhelmingly gross, unintelligent, incorrect generalization statement to say.

This guy is a Troll, definitely. Saying inflammatory and stupid stuff to elicit reactions. Ignore him.

3. More expense. Examples: Cost of Nitrox (vs. air). Putting/keeping your cylinder into/in oxygen service if the Nitrox you will purchase will be partial-pressure blended in your cylinder.

In many places I dive nitrox is free.

I know a lady who will not dive on Nitrox because she swears it makes her feel ill, which I thought odd as I too feel much better and less fatigued using it, but I guess everyone is a little different....

The days of diving air left me much more fatigued

Consider extending your safety stop to at least 5 minutes, and even a bit longer if your air supply allows. Fatigue is a common symptom of preclinical (mild) DCS.
