The Ewa-Marine U-AX Housing is an economical solution for using any autofocus SLR camera with shoe-mounted flash near or just under the water's surface, manufactured from double laminated PVC and with an optical glass port.  It is rated for dives of up to 66 feet (20 m) depth; perfect for snorkeling, shallow diving, or generally sandy, dusty, and humidity weather conditions.  The U-AX gives your camera and flash the best possible protection while being fully operable.  When not in use, it is relatively light and takes up little space.
