Overhead environments and open water scuba divers

[PfcAJ]

there are hundreds of "overhead" dives that are perfectly safe.

Don't confuse 'safe' and 'without incident'. They are not the same. Plenty of people drive without seatbelts and don't get hurt. That doesn't make it safe.

Come on Bob, you seem like the loquatious type. Don't just do a drive by slamming all my posts, pull over and enlighten me.
And I assume you mean a Green Beret who has accidently blown his head off with his own M-4?

In order to be enlightened, you'd have to know a little more about what happened, and why, than you apparently do. There's several good books out there on the subject.

Comparing Exley's to that of vacation divers who wander into caves is ridiculous ... and a waste of my time to even attempt to explain why.

Well, his knowledge, or lack thereof apparently killed him. Or as they like to say on SB, he dove beyond his training.

I fancy doing some 900 foot deep cave dives. Don't want to go beyond my training though. What course(s) do I need to do?

You are correct, the average vacation diver on a follow me dive is a lot safer than Exley was on any of his dives of notoriety. Apparently he was an incredible guy who did unprecidented things and to no surprise wound up dead. No explaination needed.

For you sir I reccommend nothing less than PADI AOW, an AL80 with backup 2CF Spare air. You will need to descend quickly.

 

[PfcAJ]

youve really got it figured out. you must be basing all this on your vast amount of deep cave experience.

Had Sheck lived thru his deep air endeavors, his contibutions would be unsurpassed.

I don't understand this. He was breathing trimix when he died.

I don't recall mentioning anything about caves.

A number of commercial divers go to these depths. Can't say I've ever enquired, but I would certainly reach out to their schools and experienced divers as a starting point. Also making sure your life insurance covers this would be wise.
