Dry BoxDry boxes are used to keep material dry. One kind of dry box is used by divers and, typically, is good to 30 meters of depth. 1 Such dry boxes contain assorted gear dry such as photographic equipment and supplies. Other dry boxes are used for scientific specimens and can be "nitrogen-purged" with the aid of "bubblers". 2 External links - 1 http://www.cheapscubagear.com/2233-Otterbox-3000-Drybox.html
