The D10 was great!! It was a true waterproof diving P&S, whereas most advertise 3.3 meters as the max depth before the pressure fills the camera with water. It wasn't a $1000 rig for deep diving, but for fun shallow dives, it was one of very few cameras that went below 10ft.
This new D20 isn't the most attractive specimen, but it should do the trick!
Any specs on this guy -- resolution? Video resolution? FPS? Aperture?
The D10 specs were:
33ft depth 4 feet shock
Awesome clip to attach to your SCUBA gear
