Laziness, complacency or is it just me?

That trail behind a divers head might not come from the tank o-ring though, it might come from the tank valve or the hose or hose o-rings on the first stage.
Regardless, yes the leak is minimal.

Ill tell you one thing though - you REALLY don't want a full out blown tank valve o-ring event when you're at depth with a less than attentive buddy, cause you'll have very little time to get alternate breathing gas supplied, even if the tanks full when it blows.
I've seen it first hand as I was "fortunate" enough to have a buddy experience just that....

That's one of the reasons DIN valves and regulators are used in north Florida. The O ring is on the regulator.

Not that I'm disagreeing with you, but even with a half full tank, you should have time to ascend or link up with your buddy and ascend. There was a thread saying that at 1/2 a tank you have about 4-5 minutes before your tank runs dry.

Not with a blown tank valve o-ring it wont. Not even close...

I do not get bent all out of shape over a leaking O-ring. Anyone who dives in the Caribbean should be accustomed to the occasional leak. I can stay down longer than dead people as it is, why would a few bubbles matter?

Now, if my regulator has a leak, I would be most aggravated, I usually also carry a spare and in some 40 plus years of diving have never needed my spare. Usually I find people who obsess over tank O-ring leaks should worry more about learning how to care for their own gear as a better priority.

I think it would...I'll find the thread, and we can discuss it from a standpoint more educated than me guessing at numbers.

Yep, Tigerman was right; my memory was faulty. Maybe a minute to 45 seconds at depth.

I am not really concerned with the amount of gas loss, in my opinion it is minimal. I do find the noise annoying and having watched others, the bubble stream to be distracting to others. I will usually check prior the dive and either attempt to correct it by lubing it just replace it. Normally the operator will have one handy but if not I have extras in my bag.

I just don't think I can get accustomed to it. I will stick by how I was trained since I am not an instructor or a very experienced diver. The issue is not so much the bubbles as it is divers who are unaware of their equipment.

in my 4 years of diving I have noticed that the ones who don't notice leaking o-rings are usually using rental equipment. They are the ones who don't notice their SPG or depth gauges aren't working. They are the ones I usually see being towed up by the DM's using the DM's octo. They are the ones diving without computers or bottom timers and I never see look at a dive table.
As for my obsession with a leaking o-ring and my equipment, I assure you I am fully aware of my equipment a status. It is properly maintained and fully serviced. I'm pretty positive that when I see a piece of rubber hanging from an o-ring that it is a high probability that any leak in that area is not my equipment.

I dont understand you relating noticing o-ring issues to not knowing your personal gear, but as stated, I don't have 40+ years of experience.

And I don't mean ALL diver who miss a leaking o-ring using rental equipment are bad divers or clueless. It just seem the clueless ones always outnumber the knowledgable ones.

 

[agesilaus]

Just curious, you can change the tank oring while the tank is pressurized? How does that work?

Could you please clarify what you mean by this?
Every issue that I have ever had with an o-ring has been with rental gear.
I like to think that I take good care of my gear, but I admit that I'm still pretty new to diving so I could be missing quite a few things.
