My first underwater camera was a Sealife Reefmaster.  I used my first Reefmaster for over 6 years and never had a leak or a floodout.  Recenlty Engadet and Digital Trends reported on Sealife’s newest underwater camera the DC800.  The DC800 works in or out of it’s underwater case.  Inside the SLR like case, divers can take the camera down to 200 feet.  The camera offers and 8 megapixel resolution and a 4x opitcal zoom.  The DC800 also has 5 underwater modes to give you the clearest and sharpest underwater shots.  The cost is about $550.
