About this Case:

The Seahorse SE-300 Waterproof Case is the perfect choice for keeping cameras and small electronics safe from both the elements and accidental impacts. If your gear gets knocked off the fishing boat, caught in a sandstorm on an archaeological dig, or dropped from a rooftop while photographing the sunset, you'll be able to laugh it off if it's inside the Seahorse SE-300 Case.

Like all Seahorse cases, the SE-300 employs a single-wall injection-molded construction that makes it exceptionally crack-proof, crush-proof, and shatter-proof. The impact-resistant SE-300 is also outfitted with a sturdy Neoprene O-ring that runs the perimeter of the case between the lid and the body, keeping it watertight at depths of up to 30 feet! This protective seal also serves to seal out dust, dirt and debris, no matter where you choose to take it.

The Waterproof Seahorse SE-300 Case excels at keeping things from getting broken -- including your budget!
