Sharkbanz Shark Deterrent
I'm not even sure I trust mosquito-repellent wristbands, so I'm doubly unsure about ones that claim to deter sharks. What I am sure about is that I'd much rather be the test subject for an itchy bloodsucker Invisaband than a flesh-ripping killer fish Sharkbanz.
But if you're a surfer, swimmer, snorkeler, kayaker, or other ocean-goer planning to go the ocean regardless of your (admittedly minute) susceptibility to a shark attack, wearing a Sharkbanz could save the skin on your hide for no skin off your teeth.
Sharkbanz use magnetic technology in their efforts to deter sharks from attacking humans. Since sharks are more likely to use their ultra-sensitive electro-receptors than their eyes to sense their surroundings, the magnetic waves emanating from Sharkbanz help disrupt these receptors, and tell the shark there is nothing of interest for it around--or inside--you.
According to Sharkbanz consultant and marine biologist Dr. Eric Stroud, when a shark encounters the wristband's waves the experience is "like a person suddenly shining a very bright light in your eyes in a dark room, and it's not pleasant." And with so many delicious seals and other non-Sharkbanz-wearing kiddos to eat instead, the shark is more likely that not to do a 180 and seek out one of them.
Sharkbanz fit ankles wrists measuring between 5" and 14" in diameter. They come in Slate, Sea Foam, and Azure colors.
