Depth Gauge,
"I was wondering what you would do, not what you think we should do."
While we are never sure what we will do in a given situation until we've faced it, I believe they are the same.
"Yeah, I've heard that GeekDiver, but whether it's sound advice or not, and it might be, isn't the point."
What is the point? I seemed have missed it as well.
frogxman,
"I am curious - is this a real advice? Aren't you joking? Have you tried that before?"
If a Great White wants to eat you and you are in the water, you are very likely dinner. I am not joking. All the evidence I've seen leads me to believe this is the correct approach to lessen my chances of becoming dinner. This is my plan in such an event. It may get me eaten, but I believe it to be my best chance for survival. I have never tried it with Whites, but I have tried various methods with other sharks. This method has kept other species at the greatest distance. Swimming away, they sometimes follow. Remaining motionless, they often approach quite (within arm's length) closely. Swimming towards them they've always (so far) turned and swam away. Others have tried this method with Whites. It has worked for them.
I certainly wouldn't knowingly put myself in such a situation.
