The SeaLife ReefMaster DC300 is a high quality 3-megapixel digital camera for use on land or under the water. It's rated waterproof to 200 feet when mounted in the included housing and can be set to one of three different automatic exposure modes: Land, Sea or Sea w/external flash. The "Sea" modes set the camera for optimal color reproduction in the deep blue. The DC300 is the 3-megapixel point-n-shoot model with minimal control buttons on its housing. The Reefmaster DC310 is the 3-megapixel deluxe model with a complete set of control buttons and can be changed from still to movie mode while underwater, the DC300 (and DC250) housing lacks a mode dial control.

The Reefmaster cameras feature a bright yellow, rubber armored outer housing and large non-slip grip areas to make them durable and easy to use when wet. They also feature an Instant Delete function -- after taking a picture it is displayed on the color LCD along with a "Delete Current?" prompt for 4 seconds. If you like the shot - just wait a few seconds. If you don't like it, simply hit the shutter again and it's deleted. This makes it easier and faster to keep only the shots that you want!

The 1.5-inch color LCD makes it easy to review images and access the menus. Get long battery life using lithium CR-V3 or high-capacity AA rechargeable NiMH batteries. The DC300 can also be enhanced with SeaLife accessories like macro and wide angle lenses, and external flash units. The perfect gift for the warm-water tropical vacationer or diver in your family! They also make great cameras for those engaging in water-based sports or extreme weather conditions.

And don't forget that the camera comes out of the housing and can be used liked any other digital camera when you're not diving or snorkeling. The DC300 is an easy to use camera that can create photo-quality 8 x 10-inch prints and is small enough to fit in your pants pocket.
