Seahorse makes exceptional waterproof and ruggedized cases that float too! The Seahorse SE710 case is a smaller and briefcase-size case. It features key locks and also holes where I a TSA lock(or two) could be attached for added security. The interior foam is scored for easy plucking to custom-fit various items. This is a great case for carrying cameras and other equipment. It features a pressure release valve. I swim with this Seahorse case and don’t worry about my expensive equipment inside! The bright color makes it easy to see and retrieve, should it become loose in the water.
