If you need a waterproof camera for seawater/freshwater, this is what you need. Takes great pictures in & out of the water. I do recommend getting a few extra lithium batteries for the camera but they are under $10 a piece. Be gentle with the camera because it still has breakable parts on it, it is not indestructible.
