I have two new diving heroes- buddies - friends

I 100% agree ...Yes Brett and Jill are a piece of work -- One of a kind -

I first met Brett some time after he became a NAUI instructor about 30 or so years ago . The late John Wozny brought him to one of my parties which was loaded with local and national divers. He walks in , his eyes lit up and he immediately began working the room introducing himself and inquiring about the diving genealogy of every person he met.

This attorney/diver from Maine was like a kid in a candy store ..Now he has 10 jillion dives and sooo many adventures, soo many stories

Jill was unknown to me-- She contacted me how iI don't rrecall either a telephone or mail. She had hears via grape vine that I had all the Skin Diver Magazines and the majority of all the diving catalogs . She asked if I would check on a series of US Diver advertisements which sated "Its a mans world " and sent her copies ? I checked n then there were six -- I had them copies sent to her then new dive shop.

No Thank you, no acknowledgement what so ever...Since then I have been in her company many times -- no acknowledgment-- still no thank you

Yep! they are one of a kind ...and they dive among us

John Wozny

He was one of the nicest people I met through NAUI.

Now he has 10 jillion dives

The last time I saw, he is up to 20,000 dives now. Considering his age, he had to be making around 300 dives a year since the day he was born. What a Guy!!
 
The limiting factor of a cesa is a combination of your ability to empty rapidly expanding air from your lungs and being in control enough to not panic and override your mdr.

A calm controlled diver could easily cesa from 100+ meters with no issues. A panicked diver probably can't successfully cesa from more than 60 feet.
 
Your father's incident validates the case for primary donate and a necklaced alternate. IMO, the CESA is not the problem, it's the buddy and then subsequent difficulty of finding his alternate with a panicked buddy pulling him to the surface. A tough situation to be in.

You know I had previously thought the necklaced octo was a good idea, but not absolutely necessary for a rec diver.

I figured that even if my octo got loose somehow, I could always sweep and recover -- I mean I can do so easily in drills.

I want to thank the OP for this story, it really does highlight an additional factor - add stress & panic to the occasion. Now would you want you air floating around behind you or right by your mouth?

This has been a good thread.

Seems to stay on track.

Good opinions and options, and lots of food for thought.

I hope this thread continues on a positive note so that new divers, new viewers, can
benefit and learn.

A real OOA incident with a panicked OOA diver is a huge issue.

How to deal with such a event is definitely worth discussing.
 
Now I feel I need to practice this skill.

Practice is important-of course.

If divers adopt practicing skills, such as we are discussing, it will help keep divers safe.

Sometimes we have good informative threads that do not get sidetracked or derailed.

This seems to be one that continues to educate and inform.
 
OK, in keeping with the theme of the thread--is a CESA a skill we should really frequently practice at the depths we would likely be using it?

A CESA from 20 ft? OK. A CESA from 90 ft? Ehhhh... my gut is telling me that's not a great idea to be recommending to people. Having to emergency ascend is the diver equivalent of a car crash, and I really don't practice crashing my car into things. I'm all for training for real-life problems, but this feels like one where the risk outweighs the potential benefits. Thoughts?

I do not think that training in a calm and steady manner is any way near a car crash type scenario.

Controlled ascent, regulator in hand, head tilted back with an open airway, blowing bubbles, and heading
for the surface.

It is reassuring, at least for me, knowing that you can do it if ever a real OOA event occurs.
