It's important for the best waterproof cameras to be tightly sealed against the elements. The last thing you want is to use your camera underwater, only to discover that it wasn't properly built and that it leaks.
With the Fujifilm FinePix XP170, you won't have that problem. Fujifilm has created a very well-built camera with the XP170, ensuring through a double-locking mechanism that this camera will not have problems with leakage.
