John,

The drysuit was not flooded. The vent *may* have been open which *may* have caused it to vent unintentionally during an ascent. It has also not been established that she tried to make an ascent. That idea may have come from a theory I suggested early on in the thread.

When the rescuers cut open the drysuit to apply the AED the undergarment and her chest were dry.

R..

I didn't think it was, in this case.

I have on more then one occasion I have started a decent with my vent open all the way. painful until I realize Wth the issue is....

as was said before, I think this may be the longest accident thread without mud slinging...

I assume you meant "ascent" instead of "descent"? I always do my descents with the valve open -- it's hard to initiate them any other way :)

Of course, I do my ASCENTS with the valve open, too. If you do them in a horizontal position, it's not an issue.

No, descents... if the valve is open when I reach depth, anything below a few feet really, the boys tend to get grumpy from the squeeze, so I added air on descent to keep them happy... With the vent open the added air vents as it goes in... thus the trouble with squeeze on my part.

I usually do the open neck seal squat and push the air out of my suit before the dive. it works most times to allow me to descend a bit before needing too add air. (first few feet I usually pull down the line if I am a tad bouyant....
 
My valve is never closed. As Lynne says if you dive in a horizontal position and ascend and descend that way adding air should not vent out. At the most I may turn it a 1/4 - 1/2 turn closed. Full closure takes at least 2 full turns. I want that valve open should I have to vent air. Never more than enough to take the squeeze off.

I normally dive with mine open too. People who don't normally dive in drysuits should be made aware that this is a very common practice and that Quero mentioning that she had the valve on "automatic" was in no way inherently dangerous or even unusual.

Yeah . . . I do my descents either horizontal or head down, so I don't need to close the valve. If you do them feet down, though, I can see a very uncomfortable squeeze ensuing!
 
Lynne, could you cut these into a new thread, in basic/advanced maybe?

I dont wanna be THE cause of a sidetrack...

Thanks.
 
I agree with latest posts, I dive with my DS valve "open-automatic" during the descent, ascent and swimming around. I try to be horizontal as much as possible. The only time I close it off is when I intend to float at the surface for a bit, especially if I doff my gear to get back into a small boat.
 
I never close mine,either. I also descend either horizontal or head first.
I have a wrist valve and I'm considering getting mine moved to the shoulder or adding a second. I'm assuming this isn't difficult and might even be something I could do myself?
 
I have been taught both methods, with valve opened partially for the entire dive, and the second method of opening and closing the valve fully as needed. I found the partially open valve worked best for me, but I am not a terribly experienced dry suit diver, and still learning.
