It's always a good idea to take a back-up camera. I've had 3 cameras go down in Jamaica. One just malfunctioned and I had to buy a cheap one at a gift shop on the beach. I drowned two of them. Supposed to be waterproof but they leaked anyway.Nikon repaired the last one so I got lucky. We'll see how it works this year. I'll take another one just in case. I still have a film camera I use for scuba diving that is good to 200 ft. I'm not going that far down but it always works. Just have to get converted to digital images when I get home. Sand, Sea and just bumping around can really take a toll on a camera.
Here's one of the last underwater pics I got last year with the Nikon AW100
