This Underwater Housing from Ikelite is a waterproof case enabling you to shoot beneath the surface with your Sony Cyber-shot DSC-RX100 II digital camera. It has a depth rating of 200'. The housing provides access to all important camera functions via mechanical controls. The camera's built-in, pop-up flash is usable. The case is constructed in the USA from durable, corrosion-resistant polycarbonate, which is clear to enable you to monitor the o-ring seal and maintain a full view of the camera. Housing buoyancy is nearly neutral in fresh water.
