You know how it goes: buy expensive waterproof camera. Bring on boat. Drop overboard. Repeat as necessary until you figure out that waterproof doesn't equal positive buoyancy.
Olympus to the rescue with a simple and inexpensive solution to a potentially very expensive problem. The Camera Flotation Strap replaces your normal camera strap with a foam-filled orange number that not only keeps your compact camera from the clutches of Poseidon, it also makes it easier to spot in case you're in the currents.
It weighs nothing, costs little and is actually quite comfortable on the wrist. It's a life jacket for your camera, and it makes perfect sense.
