Deeper waterproof camera on the way?
There is very little light at 40 feet, even less at 59. These waterproof cameras have tiny sensors and don't do very well in low light. To shoot at greater depths you will probably need an external flash and/or a larger sensor. I think you would be better off with a large sensor compact in an underwater housing.
