DCS in Papua New Guinea

I was diving with my wife, Kristy Hiltz, in remote Kimbe Bay, Papua New Guinea. We had taken all the necessary precautions and dived according to our computers. On what turned out to be our last dive, we sat on a rock ledge at 70 feet for 15 to 20 minutes and then made a slow ascent, completing a full safety stop. As I climbed onto the boat I knew something was wrong, but I thought I needed to drink water and wait for it to pass.

For Want of a Nail, the Battle Was Lost

It was 2004, the dawn of digital photography, and I was conflicted about whether to shoot film or digital. I had brought housings for both cameras with me to Thailand. Carrying two housings on a dive was ponderous, but I could manage it if I didn’t take two sets of strobes. My solution was to rig both housings with wet connectors called EO pigtails, which went into the regular sync socket, allowing me to connect and disconnect my strobes underwater.
