Did several boat dives last week in Grand Cayman. On the last dive, my buddy and I swam past the DM at about 50', who was showing some other divers some critters he had found. We weren't interested, so we swam on by. Back on the boat later, he asked us, "Didn't you guys hear the loud noise right after you swam past me?" We hadn't, and he told us that his inflater hose had "burst" suddenly, venting all the air from his tank. He and his buddy did a shared-air ascent, and all was well.
As I got off the boat at the end of the excursion, I noticed his reg hanging there, so I took a look at the "burst" hose. The edges were very clean - in fact, they looked more "cut" than "burst." As it happened, there was a videographer on the dive, and when we watched the video later, we noticed that our DM had been wearing his dive knife on his BC on his upper left chest RIGHT NEXT to his inflator hose. My buddy said she noticed that he had his knife out a lot during our dives throughout the day...
