PASS
I barely swim in the Ocean now, since Jaws;)
One of my friends compared to ringing the dinner bell since so many things are attracted to your flashlight at night.
The worst part is being able to find the boat when you come back up. One time the boats light broke while we were down. It was a little tricky finding the boat in 4 foot waves in pitch black.
Its actually a fantastic experience seeing all the life that comes out at night.
I made a pact with the sharks. They stay in the ocean and I stay on land. Been working well for many years.
