Any product that repels sharks while you're in the water is a good thing, right? Thanks to Sharkbanz, surfers, swimmers, divers and other watersport enthusiasts can head to the beach without a care in the world. It took three years of design, development, testing (and more testing) before the first version of Sharkbanz was released. Over the years, as technology has evolved, so has Sharkbanz, which is seen in the latest version - the Sharkbanz 2. There's a lot of science that goes into an accessory like this, all you need to do is review the results. And they're all positive.
