That’s right, with the Fantasea Line FS-51 Housing for the new Nikon Coolpix S52 and S52c cameras, you could toss it in the ocean without any worries. 
Even if it happened to leak it’s still protected by its one year flood Insurance policy (your photos are probably hosed though).
Another great thing about this is that while it’s in the case you still have access to all the camera controls and features. The price tag for this is $245, so for $500 (camera is ~$250) you could have yourself a nice underwater point and shoot experience. It’s better than that ziploc bag you’ve been using, anyway.
