Agreed. The details of a dive plan to set a record are beyond most of us, but the philosophy of setting records isn't. I got a notification that somebody liked a post of mine that lists the thread as "hidden content". It seems that not only am I not allowed to read a post I wrote, I'm not even...

There's some validity to comparing Everest to deep diving, but that comparison only goes so far. People certainly knew it would be difficult, but I don't know if anyone who actually knew anything about mountaineering ever thought it would be impossible to climb Everest. George Mallory was the...

It may seem fast considering that the first 38 minutes was less than 7% of the total planned run time, but as near as I can figure (and I'll admit to knowing very little about deep diving) the first 38 minutes probably accounted for something over 90% of the risk. Besides that, even for a simple...

What are these two cases? I'll guess that one is the Gabe and Tina Watson debacle. I'm firmly in the camp that thinks the evidence didn't come anywhere close to establishing that he intended to kill her, but if there was a law against criminal stupidity I think he might deserve a life sentence...

That was my first thought. If the computer doesn't "know" it's safe to do a 3rd dive, why would the computer indicate an NDL>0 for a 3rd dive? On further reflection I'm wondering if it's an unclear warning about the "periods of one or more weeks" part rather than the two dives per day. There...

That's a wonderful theory that probably applies perfectly well to balloons and similar single chamber objects with no internal obstructions, which therefore have uniform pressure and density throughout their volume. Unlike balloons, your lungs have hundreds of millions of alveoli, all of...

Your lungs aren't like balloons. Or bags of water, as the case may be. They're more like sponges with lots of tiny little pores. 1 cubic centimeter of lung has about 170,000 alveoli, so each one is small. Really small. If they were little cubes they'd be less than 1/50th of a centimeter on each...

If you go diving without even filling out a medical form will your dive insurance cover you?

Would you have preferred to deliberately swim against the current if that's what you had to do to start at the deep end of the reef? All dives start by progressively getting deeper, and they all end by ascending back to the surface. There's no reason any part of that has to happen quickly...

It's not even that complicated. A patient is somebody who's receiving medical treatment. It doesn't matter who's providing the treatment, how serious their medical issue is, or even if you've made a correct diagnosis. As far as supplying a 2nd tank of O2, I'd probably have told him that I can...

Just what info are you hoping for? I suppose that there's potential utility for locating stuff where the viz is limited, such as finding a wreck or some other site once you've descended. Overall I'm not seeing a lot of use for such a device.

None of us knows what we don't know. One of the things you seem to not know, and you're far from alone, is that you don't have a clue about grandpa's competence or knowledge. The only thing anybody knows about his diving ability from reading this thread is that he has very little recent...

From what I gather, the caves in Florida and the Yucatan tend to have fairly uniform depths even if that depth may be enough that even a short dive would incur a deco obligation. Of course most caves aren't full of water because most caves aren't entirely below the water table. Most caves are in...

That seems to be a common belief. As far as I know there is nothing in Caymanian law prohibiting solo diving, and the supposed prohibition is based on the Water Sports Operations Guidelines promulgated by the Cayman Islands Tourism Association. AFAIK, membership, and therefore compliance, is...

Yes, and they're all terrible at foreplay.

There's the important part. There may be exceptions, but life insurance policies generally have a contestability period, much as they have a period during which they won't pay out for suicide. If you take out a policy and tell them you're an OW certified diver who does a few dozen dives year and...

Foaming at the mouth is completely normal in drownings. If water gets into the airway it mixes with the surfactant, and forms foam.

It's not wasted time or unproductive if you can finish before retreating. Getting demerol after breaking my leg in a motorcycle accident was the day I understood how people become junkies. As I lay on a gurney waiting to get into the OR I realized that if the place caught fire I'd have been...

There's a cliche that says it's practice that makes you good, not lessons. I'm pretty sure that nobody here would tell you to take 40 one hour piano lessons next week and then spend the next 39 weeks practicing. Diving is, of course, different, but that doesn't mean there's not some overlap in...

There's the important part. Does "a short time" mean the time it took to do a roll call once they thought the last diver was on board, time for a roll call plus a quick search of the boat to confirm that he wasn't aboard, or did it take longer? "A short time" is vague and subjective. If they...
