Once you have perfected your buoyancy skills underwater, you'll likely want to capture images of beautiful reefs, caves, fish and perhaps even shipwrecks. You'll need a camera that's (obviously) waterproof, as well as shockproof, crush-proof and even delete-proof so you don't accidentally lose photos. Best is a high-definition video camera with powerful wide-angle optical zoom lenses.
