My wife and I are headed to Australia in a few months and we will be snorkeling on the Great Barrier Reef. My D10 was purchased in 2009 and still works well, although I rarely use it as I now use my phone for those shots when I don't have an SLR with me. I was wondering if the waterproof seals are still good or should I look at getting a new underwater camera? I don't have a good place to test the camera to any reasonable depth, but I doubt we will take it very deep as we will only be snorkeling. I really don't want to spend $300 to get a D30 as this trip is the only occasion in the near future that I can think of where we would use the underwater feature. Does anyone have any experience with an older waterproof camera and how well the seals hold up?
