Best setup for DC800

[Acadian Diver]

I have a DC800 with no external strobe light, what I want to know is what would be the best setup meaning ISO, shutter speed, etc... I will be diving in St-Lucia next week and by what I read, we will dive to about 65 to 70 feet max and visibility is over 50 feet.

Thanks in advance.

I dove my DC800 (right out of the box with no strobe) in auto. Nothing special and the pictures came out great (must have... one of them is on the sealife site).
Occasionally I played with the camera and shot some vids and used the flash, but at 60' in Aruba there was enough light to get some great shots.
