The Science Over 450 million years of evolution have created one awesome apex predator. You may have heard that sharks can smell blood from miles away, which is true, but did you also know that they can sense the most minute electrical impulses? Using an array called the ampullae of Lorenzini (elasmobranchs like sharks and rays have them), they can pick up ridiculously tiny electric signals. 5/1,000,000,000ths of a volt in fact (yes, that’s billionths). This sense is so fine that sharks can detect the heartbeat of another fish. Scientists suspect the ampullae of Lorenzini may be used for hunting – finding other fish in distress, or in murky waters, or even hiding under sand. ​ Shark OFF turns those very senses against the shark. While a super low voltage field (like the rapidly beating heart of an injured fish) may attract sharks, a higher voltage field repels them. Our patented active element gives off enough voltage to make the shark jerk away from it but it is imperceptible to us. The proprietary alloy that makes up the active element emits an electric field in the ocean of about 1.5 volts – billions of times stronger (literally) than what the shark’s ampullae of Lorenzini can feel. The effect on the sharks is absolutely blinding – but you don’t feel a thing.

BCB shark repellent contains a chemical and a thick black dye that repels and disorientates sharks. When tested by the US Navy BCB’s shark repellent was the only product out of 24 to achieve any success in repelling sharks. Since then BCB’s shark repellent has been used by Navies worldwide as their approved shark repellent. When this foil packed sachet is squeezed in water, the crystalline acetate produces a dense black cloud. The inner bag has an attachment cord so it can be kept close to your body.
