As a surfer, I have a healthy respect for all things ocean and that includes sharks. They own the deep blue right up to ankle deep and you shouldn’t forget it. That doesn’t mean we have to go down easy though. Sharkbanz helps in the effort to not be chum by using magnets to disrupt the electro-emitters sharks use to “see” even more than their eyes. That’s right, they have special super powers to find you flapping around on the surface that can even pick up your heart beat. Your heart beat. It knows you’re scared and probably hones in on you by knowing that the faster your terrified little heart beats, the closer he is. What are we even doing out there without some kind of protection? The magnets create magnetic waves that are the equivalent of shining an ultra bright light in someone’s face – someone who has never seen a flashlight before. I haven’t tested these out, but I don’t need to. $65 is well worth the piece of mind that they would be even a little help.
