My kids and I went out once with him not knowing it was a feeding, my kids refer to it as his stupid pet tricks. Interesting to watch, mostly yellowtails feeding but the barracuda, green morays, grouper and a few sharks, mostly nurse sharks show up.
A few years later my daughter and I were down there during an El Nino, the 4’ waves were too much for the locals so it was just us, a newly minted OW, Slate and a French magazine photographer. I was first in and the great barracuda came over to see if I was the bald guy with the food. Slate and the photog disappeared into a baitball of Yellowtail with Slates long spearo fins sticking out the bottom. The barracuda would zoom through the ball and you would see the strobes fire. I don’t know if the photog got anything other than pictures of Yellowtail snapper but I can see how Slate has lost a few mask and 2nd stage hoses!
