Rebreathers are especially attractive for photographers because, most of the time, they don't produce bubbles. However, they require far more attention than OC. You have to watch them all the time: on pain of death. For that reason, bear in mind that for the first 50-100 hours you would be advised not to take a camera with you.

The median cost of a unit is probably around $10k, but you'd probably spend $1.5k getting trained. Just like with getting married, you feel financially drained after getting hitched, then there's a honeymooon period, then the real costs start to hit you. You never finish paying.

Don't let that put you off, but make sure you know what you're getting yourself into before you get yourself hitched!
