Things you are (almost but not really) ashamed of doing while diving

5.) Clear my nose on the ladder as I exit, or over the side of the boat once aboard. Yeah, it's gross, but I haven't been able to snort for over 45 minutes, and it's probably not practical to dart into a bathroom immediately. I try to be decently discreet, but cover a nostril and blast.

Rebreathers and snot, like a horse and carriage…. Breathe out of the nose to flush the unit. It’s good manners to let the diver know there’s a massive snail trail on his face.

I know and I agree with you

A lot of people look at things without knowing any inherent risks
A case of "I don't know what I don't know - therefore I'm probably fine"

OP didn't mention if 40m was the seabed - but I doubt it is the way he phrases it and implies that he could go deeper but won't because of training to 40m only

But I am apprehensive of undercurrents that could pull you down

40 m is not always the seabed although it can be. Downcurrent is irrelevant to the post as it can happen anywhere at anytime and at any depth. I have plenty of gas, my buddy is watching me and I am watching her. If a down current happens, I (theoritically) know how to react but I have never experienced down currents yet. And I have never noticeably experienced narcosis.

So you’re diving air at 40 meters on every dive? As you plunge to the depths your NDL plummets along with it. I’m surprised your buddies don’t tell you and your impulses to pound sand for abbreviating their dives.

Well, you certainly know that you can have a 3 minutes NDL at 40 meters and that very NDL becomes 13 minutes once you go up to 25 meters, right?

 

[Dody]

Your buddy/DM is okay with that? Because it is them who needs to help you. It puts them in risk also. I would newer dive to 40m without douples so if my buddy did this... I WOULD BE VERY ANGRY.

Heu! When we do deep diving certification, the max depth is 40 meters. And we do it with single 12 l tank, perfectly safe.

I once dived Devil’s Throat in Cozumel. I was diving an AL80. There were two young girls on the boat diving 100s. For some stupid reason, (machismo had something to do with it), I was determined not to get back on the boat before them.

Their SAC was way better than I suspected and I got back on the boat after them with way less than 100psi. Totally stupid and dangerous move on my part.

This [to me] is the 'qualifier',never noticeably experienced narcosis [diving Air at 40m].
It's there and you don't know it, creeps up on you.
Please take care.

Bingo.....Took longer than I thought.

Not at all. The theory says it affects everyone but not the same. I take for granted that it does affect me. But I am still able to mentally make double digits multiplications.

Personally, just the sheer enjoyment of cutting the fishing lines of miserable pr**ks, who occasionally and, more importantly, purposefully cast, towards divers, swimming out, near some popular fishing / diving sites . . .

I don't think down current is irrelevant. If you experience a down current at 60 feet (for example), you are likely to be able to deal with it before exceeding your limits. Plus, you're likely to still have buddies nearby. If you experience that at 130 feet/40 meters, now you've been pulled down past your limits for sure. Worse that there is no help since you're down there alone. If that happens, will anybody be able to assist you if necessary? Will you have enough air to do a deco stop when you exceed your NDL? It's a big risk to begin with, but even bigger since you're separating from your buddies.

Don't get me wrong, I happen to love diving deep. I don't know what the lure is, but I love it! Plus, I have really good gas consumption (and my buddy breathes thru gas much faster than I), so if I dive deeper than my buddy (husband), I even us out a bit. That said, I'd never just descend on my own in order to reach 130 ft. It's too risky...not only for me, but for anyone who may need to assist or rescue me.

My deepest dive was to 140 ft (42.67 meters) at the Great Blue Hole. That was in a group with a guide. (IIRC, a guide is required to dive there.) The dive was planned to include a stop at 60 feet and another at 20 feet. It was amazing, but also occurred with 17 other divers, everyone keeping an eye out for any diver who may experience issues like narcosis. I loved the depth, though don't ask me why. There isn't a lot to see down there, but the formations are kind of neat to see. I would never have gone to that depth alone...nor would I go to 40 meters alone. ETA: Also, I wasn't on air, but on nitrox 25.
