Solo Dive. Fun, but I accidently cruised into a U shaped reef in the surf zone and got stuck in a "white out". I was in 18' of water with strong surge. I was lucky to have a rock with a small ledge to wedge my leg under so I didn't get sucked out. After about a minute of being in this whiteout, I decided to make a break for the surface. I made it to the surface and had to swim through the waves and swell back out to the ocean. FUN!
