ABSTRACT:
A method and apparatus for protecting a camera or other apparatus from a water environment with a flexible, pressure compensated bag-like housing which is maintained at a slight positive pressure. The housing is larger than its contents to permit the contents to be moved relative to at least one wall to activate controls by frictional engagement between the wall and control during the relative movement. The housing may be configured as a merchandising container for the contents.
