How R U on basic hand signals?

My wife is a Type 1 Diabetic and we didn't know this L symbol was for low blood sugar. I guess we'll use it now. Got the rest correct though.

Not so sure I would adopt that signal just yet. So far, both CaveDiver.net and this board are all saying that is a bogus hand signal. Just because DAN says it is so, don't take it as gospel.

After all, she may totally P*** off some stranger!

Does anyone know where the cave divers use "hold" clenched fist as an "okay"?

As for the fist on the chest - NAUI and PADI say it's low on air.

So does SSI I believe.

No idea, but it was used as an example in the hand signals article: What’s That You Say?, Alert Diver Magazine, Summer 2011, page 40, second paragraph. Actually he wrote:

I learned from a discussion afterward that he was a cave and technical diver. He preferred to use the closed fist as an OK signal rather than the more traditional open hand with the thumb and forefinger coming together in a circle. I’ve never forgotten that moment from more than a decade ago…

Since nobody seems to know this one and it is a bit out in left field, I hope the Web site caption isn’t an Internet typo that gets perpetuated from here until eternity.

I only screwed up on the "Loser" signal. I knew I was going to get hammered for it but dang it. I KNEW it meant loser. That low blood sugar sign best be saved for the partner of a diabetic as it surely is only usefull with someone familiar with the medical condition

I received an answer from DAN, which I will post in its entirety if I get permission. In the meantime:

According to the proceedings of the 2005 Diabetes and Recreational Diving Workshop, jointly sponsored by the UHMS and DAN, “Use of an “L” signal with the thumb and index finger of either hand is recommended as a signal for suspected hypoglycemia.”

(UHMS =Undersea and Hyperbaric Medical Society)

It means "lobster with one antenna". If he had used both hands then everybody would have got it right.

I agree that sign sucks but why should someone with slightly low blood sugar abort the dive? They could just as easily have a snack and continue diving. As long as they're cognizant enough to keep that level of awareness there's no reason to believe it would become a problem.
.

Being a diabetic, I have never seen nor heard of that one before. As for the low blood sugar, they need to abort right away. A snack at depth is not going to work quick enough, depth plays havoc on blood sugars and a diabetic should never dive when there sugr levels are BELOW 180. When they notice levels are low, it is not long before they could appear narced and their condition be misinterpretted. All they need to do is surface, have a pepsi and a candy bar and get ready for the next dive!

That case, shouldn't the proper sign for "I am feeling the effects of low blood sugar" be a raised thumb, to be interpreted by all other divers as "this dive is over"?
