This Underwater Housing from Polaroid is a waterproof case enabling you to shoot beneath the water's surface with your Canon PowerShot G11 or G12 digital camera. It has a depth rating of 130'. The housing provides access to all camera functions via mechanical controls, including knobs and push-buttons. It is constructed from durable polycarbonate, which is clear to enable you to monitor the O-ring seal, and has a built-in flat glass lens port. As the housing does not permit the camera's built-in flash to fire and has no strobe connector, a constant light is required in order to have sufficient illumination for clear photo and video capture (light not included). The case features a 1/4"-20 tripod mount and a hole for attaching the included hand or neck strap.
