Simplicity is the key to great pictures. So we made the new SeaLife Reefmaster RC completely automatic and easy to use: big Sports Finder, automatic winding, large shutter lever, requiring only light pressure, even at 164 feet. No need to focus, the Reefmaster takes pictures from 4 feet to infinity. ReefMaster RC (Item SL515) features: Multi-coated, glass lens, Big sports finder, Automatic winding, Built-in color corrected underwater flash, Triple element, 35 mm wide angle lens.
