I have a son, and a family to support. That's why I am very concern about any risky activities that I do, including driving.
I think I am a very conservative diver. I am planning to spray paint my hood orange to increase visibility. I am the nerdy guy with a sausage on my BC, snorkel on my hood, and a diver noise signal device.
It is interesting to read in these columns, as proportionately, divemasters and dive instructors lead the category in incidence of death, vs. the recreational folks. With a ratio of probably 2000 certified divers per instructor, you see instructors dying with much larger frequency.
I think that underline the risk in the sport. Perhaps when one get overconfident, dive deeper, dive alone, dive without a buddy, or dive with old equipments - we are more likely to experience a life threatening situation. I am not saying that experience equals increase risk.. These folks are doing at least 300 dives a year, and certainly their risk is increased accordingly.. But I sense that their risk might be equal or greater than an average joe diver like you and me, because they take more risk - when it is not risking their customer's life.
I see videographers as a group of diving professional who usually do not have a dive buddy, they usually are swimming way behind the main group, to get photos of interesting fish, etc... That is why this diver was ignored by his buddy and the main group.
It is very boring and tedious to be a buddy to a videographer. That's probably why the guy dove alone.
