Shooting underwater video of stuff that can kill you, ain't for everyone..
So, don't try this at home..

 

Shooting video of Great White Sharks, even in a cage, is an exhilarating experience! Especially in the freezing waters off Guadalupe Island, Mexico. Thre is nothing like an 18 foot Great White slaming into your cage with enough force to knock you off your feet.

Shooting video in the open ocean, literally eye to eye with sharks isn't for the feint of heart.

Cave diving is probably my favorite activity on Earth. Amazingly, I can relax more easily on a cave dive than anywhere else. So quiet, so peaceful, so deadly. Before every cave dive, we get a death count for that cave since the last time we dove the cave. Its SO easy not to die on a cave dive, yet some people will always find a way.
