The Trip of a Lifetime

IN 2018 AND 2019, MY HUSBAND AND I traveled to 50 locations in 35 countries over 14 continuous months, spending more than 250 hours underwater to research a dive travel guidebook for National Geographic.

Broken Leg in Bonaire

While walking from the truck to a dive site entrance on Bonaire, my wife, Deborah, caught her foot under a root and hyperextended her leg when freeing herself. Falling to the ground, she exclaimed that she had broken her knee.

An Unconscious Ascent

WHILE DESCENDING ON OUR SECOND DIVE, I was at around 60 feet when I unexpectedly started ascending rapidly to the surface.

I Didn’t See That Coming

MY HUSBAND, BARRY, AND I got our dive certifications in Cozumel, Mexico, in 1994, and since then it has been one of our favorite destinations. We spent three weeks diving there in the summer of 2001, following our routine of running, exercising, and diving twice a day.

Healing Without Worry

AFTER I SPENT ALMOST 20 HOURS in a hyperbaric chamber over five days, life there had grown tedious. The last 15 minutes, however, were not only exciting but highly instructive. I learned that if you don’t know what you’re doing, don’t touch anything or do anything without first asking permission.

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.

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.
