I've been seeing a lot of ads for a "DiCAPac" underwater housing. It's\nbasically a robust waterproof plastic bag with a window for the lens\nto look through. It also has a few places for your fingers to reach into\nthe bag to work the controls.\n\nJust search for it on Google or eBay and you'll find dozens of them.\n\nDoes anybody have any experience with this item? How does it compare\nto a full ($$) underwater housing? I realize that this bag can't\ngo as deep as the fancier housings.
