My dive buddy (and real-life buddy) Will and I used up about 1500psi worth of air just hanging out on the bottom and messing around with the watch and the Sofirn SD02B light, while James Roh, who shot this piece, eked out some great shots in really low light. Three fellows in their 30s, all having way more fun than they should be messing around with glowing watches and other gadgets at the link bottom of a spring.
