PCMag: Do you use or have you seen any cool waterproof technology?
NC: H2O Audio makes underwater housings for the iPod, iPhone, and iPod touch, which are pretty cool. You'd be surprised how clear the audio quality is underwater! Also, I love using my underwater housing for my PowerShot G7. I've taken that on many training trips and free dives in the ocean.

PCMag: Are there any apps you use specifically to train? What other apps do you use, like, or love?
NC: Since I have full-time coaches, I don't use any apps to train. For cooking, I use Mario Cooks and How to Cook. Mario Cooks is filled with regional Italian recipes, extensive information about Italian wines, the history of Italian food, and HD cooking videos. How to Cook is the digital version of the highly popular How to Cook Everything cookbook. When traveling, I use GateGuru to find places to eat at the airport.

PCMag: What is the one piece of technology you could not be without?
NC: My iPhone 4S. It's completely changed my life! I couldn't imagine not having videos, Internet, apps, photos, and music at my fingertips.

PCMag: What are your favorite things to shoot?
NC: I love shooting everything from still life to underwater life to landscapes to people. I was the official photographer at a friend's wedding last year. Even though the photos turned out beautifully, I was a stress-case and don't think I can handle another wedding!

PCMag: What gadgets are on your tech wish list?
NC: A Canon EF 16-35mm f/2.8L II USM lens and a Canon EF 24mm f/1.4L II USM lens.
