We went to the Caribbean for vacation every year, and every year we had to replace our waterproof camera due to leaks. We replaced 3 of Panasonic Lumix DMC TS20 and the newer version TS30. The pictures and videos come out great but none of them last long at the beach, under shallow salt water. We’re very careful and followed the instructions of using and maintaining the camera, but it didn’t help. Now, we use action cameras, GoPro knock-off but work beautifully.
