Digital-camera makers have boosted resolutions, shrunk sizes, and squeezed a bevy of features into their products. But they still haven’t figured out a way to make their cameras waterproof. Digital circuitry, it seems, does not respond well when introduced to water. Until it does, there’s always the PT-002 protective case from Olympus ($130; 800/645-8130,
). Just 14.5 ounces of transparent polycarbonate, the casing keeps your Olympus digital camera high and dry when you take it onto the ski slopes, out to the beach, or into the briny deep. The PT-002 casing is compatible with four Olympus models–the D-220L, D-320L, D-340L&R, and D-360L–and is waterproof to a depth of three meters. A $30 maintenance kit gives you some silica gel packets and extra O-rings to keep the PT-002 watertight. When you bring your $400 digital camera on a snorkeling excursion, the last thing you want it to be is all wet.
