No underwater shooting would be possible without a suitable casing. This protection sealed by an O-ring is equipped with buttons and levers that allow operating all the camera controls. Adapted to each model or range of device, the boxes are either in polycarbonate for dives 131 to 196 ft (40 to 60 m) deep or in aluminum to reach 328 ft (100 m). A plate supplied with one or two handles intended to fix the external flash and maintain the camera for the shots completes the box.
