Diving has become somewhat of an obsession. As the number of dives increases so does my curiosity of going deeper and staying down longer. Naturally the progression involves going from a single tank setup to twins with additional stage bottles if needed. While that's the norm I've also noticed that there are a few who skip the twins all together and jump straight into a rebreather.

Show up with one and you'll realize that dive buddies no longer want to dive with you. The following link is an interesting article that discusses current rebreather trends in the industry. Keep in mind that Nitrox was once taboo.
